Worm Watch Lab Talk
The existing #clutch apparently wasn't big enough for her! Good luck counting the new ones. 😃
Suddenly, eggs! One #egg followed by a #clutch of three
They're little bubbles in the agar.
If the timing shows up in the right panel as 'Egg at: XX:XXs', then the mark counts when you finish by hitting 'next worm.'
click on the video to get it playing again. 😃 Also, these three eggs were laid at ~2 seconds, not 9!
You can always restart the video, or go back to a specific time by dragging the blue progress bar to the right time. If you can't make marks
Sadly there are some really unpleasant times ahead for wormies that can't lay their eggs... they hatch while still inside!
Not going to get tricked into losing the worm today!
Little #dumpy with a big #egg at 1s
messy #impacted And X marks the spot!
The little one up top is a baby worm, from one of the eggs laid earlier by the adult here. They're so tiny!
Correct, we don't mark the ones already there as eggs laid. But it is neat to see so many of them!
It's the edge of the petri dish, the camera has lost track of the worm.
I have seen the constant playback on Chimp&see talk a few times. Maybe a rare glitch with the html5 player? I can't reproduce it reliably 😦
Cool 😃 Well, not cool, because they're a problem, but neat to see something else alive other than c elegans in these videos.
A better view than the one I found! The way it moves makes me think it may be an insect on the underside of the plate? A very small bug.
Very odd! It looks almost like an 'empty' egg, but I am not sure if they can lay such things.
The magical invisible eggs, didn't you hear about them? (You're right, nothing here.)
Yes, all these eggs were laid before, and shouldn't be marked. She's just playing with her unborn kids. 😃
They're baby worms just poking out from under mom. Looks like they don't want to move much either!
Nice one! I think the record is still nine eggs, I keep hoping to find the record breaker. 😃
Quite the #impacted / #pvul on this little lady, I think I've seen her on Talk before...
#hat_trick! Seems she does a lot of them, two old clutches and one new one at 16.
Found the worm again! Good little camera.
Nighmare clip! I counted 5, saw @WEBs counted 3... Now I think there might only be 4. Definitely 1 at the very start, though.
Single #egg at 25, and then a #clutch of ..four? at 29.
#egg #clutch of three at 7 seconds.
Busy lady! I'm still hoping to find the video that beast the record of nine eggs. One day...
Yup! Hiding under mom before wandering out into the great wide open petri dish. 😃
UFO! There's a dark spot passing across the top left corner at 24-26s. Something moving behind the plate, or someone casting a shadow on it?
I just got this magician to classify! I'd recognize those crazy dance moves anywhere. 😃
Little #dumpy with a very large #egg for her size at 23! @JJBehr got this one before me, hello! 😃
She's so #tiny! I've seen shorter worms, but none skinnier than this one! Those eggs are almost her whole body width!
Alright, who turned the worms to 'tiny #egg' mode? Three in a row with very unobtrusive laying events. At least she's not sitting on them!
Another stealthy #egg layer! #double at 12
Tricky one, small eggs hiding in shadows! I marked an #egg at 24 and a double at 28.
She is a cute little dumpy! One of the smaller ones I've seen, I'm starting to recognize her. Maybe you'll catch her next egg before me!
Busy girl, sitting still since AWS0001gng laying eggs, out of focus or she's just churned the food up too much, they're blurring together.
Funny 😃 Actually everyone's on a diet! They're raised on a much thicker bed of food, but it's hard to see them clearly amid such luxury.
I've noticed on some 'impacted' worms, the bump goes in and out with their movements. Not sure of the significance, sorry.
No new eggs laid, but the worm's got an #impacted #protruding mess stuck to her.
Don't blink and don't play through too fast! #egg laid into an existing clutch at 10-11, doing its best to blend in to the pile.
Stealthy double #egg at 23.
A close relation of dumpy, not quite as short or as fat. She's an #ELD, and she's #fast, look at her zoom!
😐 You're not seeing lots of repeats, are you? I know it's hard to tell with most of the videos...
I wonder if she realizes she just ran straight over her #baby! Good thing they don't mind.
More messes! I marked 6 eggs here, 2, 1, 3. Not sure about the double on the first one, I thought it looked too big to be just one #egg.
Weird! Her vulva must be further back than usual.
The food is thickest at the edge, so maybe she is where she wants to be now! She is moving, even if it's incredibly inefficient.
The worm came back in the mean time to deposit two eggs! How kind of her to stop by the stationary camera to do it.
A good stick impersonation for you, WEBs!
No idea! Though I don't think anything so elaborate is going on, just that not all the mutation data was input along with the videos.
#dumpy with an #egg laid at 10s. Hi @ElisabethB!
#clutch #egg 3 laid all at once, one frame nothing, and then suddenly all three eggs! Most times they squeeze out one after the other.
Little #dumpy laid an #egg at 4s. This one's not an ELD, unspecified type.
This worm lays in twos! Three old pairs, two new ones at 26 and 34. #egg
It's a #double double egg laying! At 1 and 9.
I count three new eggs at 1s, added to the massive pile already laid before.
Long and slender, the polar opposite of the cute little dumpy worms.
@stonepenny was here first! Nice 1 + 2 #egg laying.
Looking back a few videos, this baby's been around for a while. They do hatch relatively quickly, neat timelapse: http://y2u.be/xzgJlsqZpJQ
It's a big bubble. Big enough that the camera prefers it to the worm, unfortunately!
Just resting 😃 See her move around a little later: AWS0000wqh
http://dev.biologists.org/content/129/1/221/F1.expansion.html Pretty pictures!
small bulge visible. No egg laying activity between then and now, and the bulge has gotten much larger! Eggs stuck in a protruding vulva?
I'm really not sure anymore, the bulges vary in size over time on an individual worm. AWS00017df Same worm laying an egg earlier, with a
I think you're right! Remember to mark each egg that you see being laid, even when they're laid all together.
Wow! That's a lot of action at 22. #live-birth #baby in that mess? It looks like the baby goes back under the pile of eggs/mom.
Examining her offspring. 😉 (They don't have 'eyes')
Changed your mind WEBs? 😉 I took a look around, no baby sign before this, 2 videos after there's a baby underneath that escapes. AWS0001973
Lots of old eggs here next to the worm, but I don't see any new ones.
Exactly what it looks like, a big blurry smudge. 😉 Something below the petri dish, maybe, that's out of focus.
An odd #egg laid at 28, quite far back from the normal vulva position.
once they get close to hatching. It's a bit of a pain, but regs are regs... 😄 😄
Obviously if the worm doesn't sign the privacy disclosure, we're not allowed to photograph her children, so any eggs have to be blurred out-
A very accurate name, though not a very kindly one! Poor dumpy darlings. They do seem healthier than a lot of the variants we see, though!
https://www.youtube.com/watch?v=xzgJlsqZpJQ
Maybe, the video isn't high enough resolution to really see what's going on with the eggs. You may like this... probably want to mute it!
A tricky one, she's built up a big file of food and it's distorting our view. I think it's a clutch of eggs, blurred into a wide blob.
even more #stubby
More #stubby!
#stubby
X starts. Z for eggs... Large fingers? 😉
Just because there's a lot of eggs laid already doesn't mean she's done!
The camera is trying to get away from the edge, but it's just too interesting! #glitch
#egg at 29, sneaking in just before the video ends.
Check out figures 4 and 6! http://jcs.biologists.org/content/115/4/857.figures-only
There are at least two groups of mutations that cause morphological defects, Protruding VuLva (Pvl) and abnormal Eversion of the vuLva (Evl)
Luckily the camera isn't fooled by such shenanigans! If they want to lose the camera they have to find something bigger/higher contrast!
It does look like there's an egg laid early on that stays stuck for a while! I confused it with the impacted egg coming in and out of view..
too large to be a single egg stuck. On my list of things to look up now!
I'm starting to doubt if all of these are impacted eggs.. sometimes it seems like it may be a deformity of some kind around the vulva,
The man in the agar. Forever trapped, forever watching worms lay their eggs...
They do 'rest' sometimes. She does start moving after a few more clips, though not very energetically.
They can 'smell' the food area to get back, no lost worms. The cameras are another story!
I love the stubby ones! Direct counter to the long and slender elegant worms, they're just cute 😃
Hit the goal again! A bit after British Science Week came to a close. 😃
PS we are now 62% done.
I knew I recognized this one!
Looks like more than one to me. The pile of eggs already there makes it hard to count the new eggs.
If you have further concerns with the legitimacy of the science coming out of the platform, I suggest you contact the creators directly!
https://www.zooniverse.org/publications
project papers for any project that has published work. They've all dealt with these kinds of questions, successfully.
Now there's a question I can answer definitively. There is a lot of literature. Check out the 'Meta' section at the bottom. Or any of the
First person to see this video, but definitely not the first one to see this worm with her little #baby hiding underneath.
Shedding a chunk of... lets call it #egg-debris? between 19-23. Might be one egg in the mess? Not laid then, but finally getting unstuck.
They must have found the invisible worm with the invisible eggs. Gotta get out your x-ray glasses? They'll work on recorded video, right?
The camera doesn't even budge! That bubble is just too exciting.
C. elegans is actually used in studies relating to longevity. 😉
The worms are manually inspected when put on the plate, to determine which side the vulva is on, sometimes they get it wrong. Not often!
Busy worm! This is a nice example of what egg laying looks like compared to food clumping up, too, since she's in a thick area of food.
That's neat, it does look like the same egg is remains stuck. I wonder the impacted egg will get jostled free after a few more eggs laid?
subjectivity in the classification, there is or there is not an egg laid. Any improvement of each person through 'biased' learning is good!
You don't seem to understand, the entire purpose of this forum is for people to get assistance in learning how to ID the videos. There's no
When eggs like this are laid it looks like a normal egg laying, but then it moves with the worm. If you see that, mark it!
It is an egg, and it is stuck! I can see the little bump of the egg at the start of the video, so I wouldn't mark this as a new egg.
You've found one of the frantic button mashers on talk! Unfortunately they seem to only communicate in hashtags and.. Finnish, I think?
3 #egg layings and quite the clutch of eggs laid earlier at the top! They don't always sit still forever on big clutches!
This bubble is becoming a common sight! I wonder how many videos there are, staring intently at it.
-data analysis. I'm simply a volunteer helping out, so all my 'evidence' will be anecdotal from my own experiences.
I understand it quite well. I can't answer your question about controlling for possible classification biases, as I am not involved in the -
Earning her title as an egg laying defective! Double #clutch laying, 3 eggs each... I think.
And I don't think you've done that many yet! (You're getting there, I know. Maybe in a month? 😃 )
Not the repeats! Very weird, the only cause of repeats I know is when a user has seen all the 'active' subjects. There are 20000 active--
Kinking, twitching, coiling, this worm has it all. Still managing to move around quite a bit with all her issues, though!
It was not, but interpret how you will... It was an offhand compliment to @WEBs, who spotted the same egg I did, in this very messy video.
It would be interesting to hear what @aexbrown has to say about it. As a user, it really doesn't effect my classifications.
A 4 #egg #clutch at 7. Messy but countable!
Multiple #egg layings into an already massive clutch of eggs.
My 200th egg laying video! Well, more like ~210th, as I didn't save the first dozen or so when I started. A nice personal milestone. 😃
The tracking software has taken a little vacation here to wander all the way from the worm on the food spot to the edge of the plate.
0 eggs. Only mark when you see the eggs being laid.
A much larger source bias would be from 'super users.' I don't have the numbers but I guess ~20% of the classifications come from ~10 users
know that there is going to be an egg laying event in the video. I watch videos without any previous markings just as carefully, though!
Hmm, a small bias? There are perhaps 4-6 people I recognize while classifying, and I don't classify those videos any differently, I just -
Leaning on their keyboard? We don't know why users mark 100+ eggs, but they are easy to filter out of the data, so don't worry about them.
They are definitely eggs, not a food pileup. See AWS0000wpl for when they were laid, this worm sits on this pile of eggs for a long time.
#egg 19 One of those times previous marks are nice. When it's someone you know is a zealous egg finder it's worth it to pay close attention!
3 #egg laying events, starting at 17. Curiously small eggs, not nearly as obvious as most.
Another stealthy worm, laying small eggs that blend in very well! I count five #egg laying events, 2 clutches of 2 and 3 eggs each.
That's a big egg for such a little worm! #egg at 12
I had to slow down to answer all the questions! There were 3000+ people on the project during British Science Week. Quite the rush!
Need more space, see discussion! @aexbrown it would be great to hear your opinion on what is going on with this poor worm.
Congratulations! You're catching up to me in a hurry, WEBs! 😄
The outlining software's confused by the pile of eggs and can't figure out what end of the worm is the head, it's switching back and forth.
Yup, the edges of the dish confuse the tracking software if the worm wanders too close to it, it ends up stuck staring at the edge.
Yes, the little one is hiding under mom.
It's a baby worm. Sometimes they like to hide out underneath the adults.
There is a baby worm hiding under the adult, the little 'bubbles' are moments where it partially wiggles out from underneath.
A lovely video if I do say so myself. 😉 Looks like you have a good grasp on worm watching already!
Stealthiest egg layer ever! One #egg at 20s, I nearly missed it.
This sounds like an odd issue... Can you please try switching browsers to see if that helps?
Camera lost the worm and we are now staring at a bubble. Bubbles, sadly, do not lay eggs.
Quite the dancer, she's got those pirouettes down to an art! It's nice to see some elegant movements highlighted, thanks for sharing!
Agreed, looks like a neat single egg at 22. Looks rather odd after the worm wiggles it free, maybe just because of all the churned food?
Those are more babies! Two I think by the head, one or two by the tail, and the 'lonely' one that's gotten away from the pileup on mom.
No eggs, we're seeing the food layer clumping up around the worm here. Check out the videos in the Help and Guide if you haven't already!
The movements around the worm are a baby hiding underneath! If you haven't already, check out the Help and Guide for some clear egg laying.
#dailyzoo for a very bizarre worm!
What a worm! 3 eggs laid, first one at 3 is #impacted, then releases at 10, and then she lays two more at 11, the last egg also impacted.
Looks impacted, a big enough lump that it's probably more than one egg stuck.
Yes, there are some overeager classifiers among us. The best thing you can do is to mark accurately!
The worm just isn't moving enough to leave the eggs behind. These are old eggs, and shouldn't be marked.
You're right, this is a baby hiding under mamma worm.
You can read more about the hardware and software used to create the videos here: http://bit.ly/1Btdy69
You're right, it is backwards. I'm not sure what causes the software to get confused about the head/tail, I've seen it switch mid video--
Short version. 😉 If that wasn't clear let me know and I can clarify in longer than 140 char form.
-logged in users, and it was apparently causing enough exasperation and confusion that they stopped displaying them. Before my time here!
The code speaks! 1) Get random person from egg timings. 2) Display timings if not an anon user. Anon users mark even more non-eggs than-
You're right, eggs come out near the red dot in the middle, the vulva. All the eggs here were laid earlier and shouldn't be marked.
Yup, a very stealthy egg, didn't notice it first time until the worm passed it. You can see it a little near the head at the start, though.
@WEBs_in_space I have found the mysterious 'netherworld layer' 😉 She has a mild twitch but otherwise healthy looking.
That's quite the egg laying session! Nice catch 😃
Yup, could use a quick cleaning!
from all the old tracks, but has stayed stationary with her large clutch of eggs, maybe tired from all the egg laying.
The worms are recorded for 15 minutes, making 30, 30 second videos, so you can see the same worm multiple times! Looks like she was active-
Yes, it's caused when an egg gets stuck in the vulva on its way out. Another type of 'egg laying defective' behavior.
PS if I've skipped a question you want answered, just give it a bump. I know I miss a few coming back to 15+ hours of messages.
And probably loving it! Their natural habitat is soil, they are used to navigating through 3 dimensions, not just a flat plate.
So she might be going for an explore, but probably won't lay any eggs while outside the tasty drop of food. 😃
Neat fact: They prefer to lay their eggs in areas of higher food concentration, so that their offspring have a higher chance of survival.
When the worm is in a thicker area of food it can be hard to see what's going on! You're right, no eggs here.
Correct, only mark newly laid eggs.
Neat! So the camera, worm and the agar medium, were all just cooperating perfectly to get a nice clear shot 😃
You are now officially as worm crazy as me. 😃 There are at least 30 videos of each worm, sometimes more I think... so some get familiar!
Correct, we do not mark eggs that were laid before the video starts, only new ones!
Not a baby, it looks like a crack in the food layer.
You're correct, no new eggs here. She's sitting on a pile of previously laid eggs, we don't mark those.
I am having trouble counting how many eggs were laid here! Three big clutches on top of at least one clutch from before. #dailyzoo
You're the correct one! Some people seem to get excited whenever they see an egg...
Just a confused camera that's lost it's worm. The worm on this plate is roaming unwatched, bet she's up to no good. 😉
If you are curious about this behavior, you might like to read this: http://talk.wormwatchlab.org/#/boards/BWS0000003/discussions/DWS00001s0
She seems to want to ask us something. 😄 If only there was an egg to dot it!
She's inaccurately marked, notice the vulva marking is on the wrong side, the head marker is on the wrong end, too. It happens occasionally.
Some small speck of dirt or dust, normally the plates are kept super clean but sometimes a bit of debris makes it in.
Classification tip! Speed up classifying these sluggish worms by clicking and dragging the progress bar to play through the video faster.
A very short worm! They come in all sizes.
it loses the worm entirely because the worm left the food area and went wandering close to the edge of the petri dish.
Yup. I believe the camera focuses on the highest contrast thing in view, and is initially centered on the worm. In AWS0001fqc you can see-
All our worms here are hermaphrodites, so technically 'it,' but there are also pure males, so calling them she seems appropriate. 😃
Yes, these were all laid previously, no need to mark. Coiled worms that sit on their eggs are the hardest to figure out!
The coiling behavior is caused by a few of the genetic mutations these worms have. Curiously, most coiling worms lay eggs just fine.
Most people do get it! The interface shows you if anyone else has marked an egg, even one person. The majority get it and don't mark them.
I'm not sure, maybe some dust. For scale, the worms themselves are only 1mm long.
You can always go back! Clicking the video restarts it, you can also drag the blue progress bar around to any time in the video.
'Outside' is off the spot of food. She can tell there's nothing tasty out there.
Nice and clear egg laying!
There are two old eggs here, a lonely one in the bottom right, and one still in contact with the worm's tail. No new eggs.
The bump near the tail is just the background food clumping up, note how it's where the worm touches the dark trail in the background.
You are correct, we only mark when new eggs appear.
Please mark these! Egg laying is when the eggs appear near the red dot in the middle, check out the Guide and Help for more examples!
You're correct. 😃 No eggs here, whoever marked it just made a mistake, no worries.
Yup! The crazy high egg markings are actually the easiest to filter out, as there's no chance it's real data.
Correct, no eggs laid here.
It's a bit of the food medium going over top of the worm, it'll work itself free as soon as it moves a bit more. Lots of eggs, none new.
These were all laid before the video started, don't mark. Check out the Help and Guide through the main interface to see some eggs laid!
and also look for any sudden changes that might be a new egg.
These are all old eggs. It is tricky to see when there are so many! With videos like these, I compare the egg piles at the start and end,
You can replay, until you click 'Next Worm.' If the keyboard shortcuts don't work, you can click the 'Egg Laying' button below the video.
It failed to properly lay the egg, so it has an egg stuck half out. The dotted thing is probably dust, the worm didn't like the feel of it!
Little larva! The worms are on the plates long enough for some of the eggs to hatch, and we get to see the babies wandering around too!
Egg laying defective worms sometimes lay eggs in a #clutch like this, try and mark each egg if you can count them.
The egg is #impacted, the worm hasn't properly released it. Mark these only when you see it being laid, same as a normal egg.
These are all 'old' eggs, laid before the video started. New ones come out with quite an obvious 'pop'!
Ouch! Looks like multiple eggs are #impacted here, that can't be pleasant. You're correct not to mark any eggs in this video.
Yup! It looks like it might be #impacted, as it moves with the worm.
Just focus on making your own classifications as accurate as you can!
Don't worry too much about those mistaken classifications, it shows even when only one person has marked an egg, so they do show up a lot!
That doesn't look like an egg stuck to her tail, but I'm sorry to say wormy poos are too small to see. @aexbrown Any ideas what this is?
These are eggs that were laid before this video, the worm has moved since they were laid, and finally leaves them behind in this one! No poo
Baby worms! One on the right, and one that's underneath the parent worm for a while. They go over/under each other, fairly normal behavior.
'User has marked X eggs' shows up even if only one person has marked it, so we see all the mistaken marks. Don't worry too much about them!
Yup! Some worms will lay large clutches of eggs, some are rather lethargic and stay in the same spot. When combined we get a mess of eggs.
No eggs here, just clumped up 'food.' It does look almost like an egg laying, though, good eyes!
Four egg #clutch laid at 23.
-people that get it right, so the occasional overzealous marker doesn't mess up the data!
Welcome! You're off to a good start! Don't worry about the videos where people have marked eggs and there weren't any laid, there are more-
#dailyzoo for weird and wonderful behavior! Worms go 3D!
A few too many links to fit into a little comment! Continued the science discussion!
Check out this video of a worm entering a crack in the food to see one from a different perspective! AWS00013pb
The worms are actually incredibly flat! Their natural habitat is soil, so they're used to more chaotic conditions than a petri dish.
Large clutch of eggs, one laying event at 26, I think 3 eggs but it's hard to tell when there's a big pile already there!
Take a look at the two videos before this one AWS00013pb AWS00013pc There's a crack in the food layer and it crawls in. Very cool!
I think this guy is underneath/in the layer of food instead of on top? At 11 seconds it looks like it pokes its head out onto the surface.
Surprise worm! Nothing in view initially but it shows up at 12 and the camera goes back to tracking.
That's a little baby! Actually not so little, it looks rather large, must have been laid very early.
No egg laying here! Only mark when you actually see a new egg popping out of the side of the worm. What a mess here, though!
Is there is a hole(made by the worm?) in the food here? Looks like it manages to get under the food layer for a little bit.
Four eggs laid, 6 eggs already there, one wiggly larva, and I think one more hiding underneath mamma worm. A very busy worm!
Three eggs in a clutch. Two eggs laid at once looks pretty normal, but more than that and they look like they're vomiting out eggs!
You can see the two eggs clearly at 20s, at 23s the worm has both of them stuck to its side, they vary in visibility after that. Very messy!
I don't see an egg laying 😦 I see four eggs already laid, two clear ones in a pair, and two in the mess the worm is making in the food..
That's a tricky one. I think it might just be the pile of food, would have to see the next video to see if it leaves an egg behind...
Live birth sure looks uncomfortable for these guys... #dailyzoo
Something stuck to the worms tail? Looks a little too long to be an egg.
That's odd. I just got this one, and didn't see any previous timings for it.
Correct! You should only mark eggs when you actually see them being laid.
Lost the worm at the end of the video as it wanders too close to the edge of the plate.
Very funky looking trails from this worm, caused by the slip-sliding sideways motion that erases old and new trails alike.
Taking a slow straight wander #outside
4 individual eggs laid. Hi @2ndgm!
Wandering just #outside the food, reverses at the end and finds the food again.
3 videos with an egg to the bottom right, 4 eggs stuck to the worm, and the worm not moving much. After the 2nd one I went 'wait a minute..'
It's like she's teasing me! 😃
I've seen 3 different videos of this little guy laying there with these eggs, and STILL haven't seen the one where she actually lays them.
Hey Els! Fancy meeting you here! 😃
Five(?) eggs laid, two pairs and one(?) just before the clip ends, can't tell if it's another double or just the one.
What a mess! I don't see any egg laying going on here, all the action happened before this video.
Welcome to worm watching! You're off to a great start.
4+ eggs all laid in a clutch.
stealthy #impacted egg laying, also hi @2ndgm! First time I've seen a name I recognize from talk as a 'previous timing'
I think I caught all the egg laying action here but what a mess with so many eggs already there with a kinking worm in thick food!
I think I see an impacted egg at the start of the video, the baby worm erupts from it, and then the egg slowly deflates over a few seconds?
What a sweet little worm, cuddling the eggs! I know it's just random behavior and getting a little stuck, but still! #dailyzoo
Someone got up on the wrong side of the bed today. #egg laid on the side opposite the red dot.
No eggs here. The gel the worm is moving on is a bit thick here, it confuses the edge-finding when there's clumps of it piled up.
The existing #clutch apparently wasn't big enough for her! Good luck counting the new ones. 😃
Suddenly, eggs! One #egg followed by a #clutch of three
They're little bubbles in the agar.
If the timing shows up in the right panel as 'Egg at: XX:XXs', then the mark counts when you finish by hitting 'next worm.'
click on the video to get it playing again. 😃 Also, these three eggs were laid at ~2 seconds, not 9!
You can always restart the video, or go back to a specific time by dragging the blue progress bar to the right time. If you can't make marks
Sadly there are some really unpleasant times ahead for wormies that can't lay their eggs... they hatch while still inside!
Not going to get tricked into losing the worm today!
Little #dumpy with a big #egg at 1s
messy #impacted And X marks the spot!
The little one up top is a baby worm, from one of the eggs laid earlier by the adult here. They're so tiny!
Correct, we don't mark the ones already there as eggs laid. But it is neat to see so many of them!
It's the edge of the petri dish, the camera has lost track of the worm.
I have seen the constant playback on Chimp&see talk a few times. Maybe a rare glitch with the html5 player? I can't reproduce it reliably 😦
Cool 😃 Well, not cool, because they're a problem, but neat to see something else alive other than c elegans in these videos.
A better view than the one I found! The way it moves makes me think it may be an insect on the underside of the plate? A very small bug.
Very odd! It looks almost like an 'empty' egg, but I am not sure if they can lay such things.
The magical invisible eggs, didn't you hear about them? (You're right, nothing here.)
Yes, all these eggs were laid before, and shouldn't be marked. She's just playing with her unborn kids. 😃
They're baby worms just poking out from under mom. Looks like they don't want to move much either!
Nice one! I think the record is still nine eggs, I keep hoping to find the record breaker. 😃
Quite the #impacted / #pvul on this little lady, I think I've seen her on Talk before...
#hat_trick! Seems she does a lot of them, two old clutches and one new one at 16.
Found the worm again! Good little camera.
Nighmare clip! I counted 5, saw @WEBs counted 3... Now I think there might only be 4. Definitely 1 at the very start, though.
Single #egg at 25, and then a #clutch of ..four? at 29.
#egg #clutch of three at 7 seconds.
Busy lady! I'm still hoping to find the video that beast the record of nine eggs. One day...
Yup! Hiding under mom before wandering out into the great wide open petri dish. 😃
UFO! There's a dark spot passing across the top left corner at 24-26s. Something moving behind the plate, or someone casting a shadow on it?
I just got this magician to classify! I'd recognize those crazy dance moves anywhere. 😃
Little #dumpy with a very large #egg for her size at 23!
@JJBehr got this one before me, hello! 😃
She's so #tiny! I've seen shorter worms, but none skinnier than this one! Those eggs are almost her whole body width!
Alright, who turned the worms to 'tiny #egg' mode? Three in a row with very unobtrusive laying events. At least she's not sitting on them!
Another stealthy #egg layer! #double at 12
Tricky one, small eggs hiding in shadows! I marked an #egg at 24 and a double at 28.
She is a cute little dumpy! One of the smaller ones I've seen, I'm starting to recognize her. Maybe you'll catch her next egg before me!
Busy girl, sitting still since AWS0001gng laying eggs, out of focus or she's just churned the food up too much, they're blurring together.
Funny 😃 Actually everyone's on a diet! They're raised on a much thicker bed of food, but it's hard to see them clearly amid such luxury.
I've noticed on some 'impacted' worms, the bump goes in and out with their movements. Not sure of the significance, sorry.
No new eggs laid, but the worm's got an #impacted #protruding mess stuck to her.
Don't blink and don't play through too fast! #egg laid into an existing clutch at 10-11, doing its best to blend in to the pile.
Stealthy double #egg at 23.
A close relation of dumpy, not quite as short or as fat. She's an #ELD, and she's #fast, look at her zoom!
😐 You're not seeing lots of repeats, are you? I know it's hard to tell with most of the videos...
I wonder if she realizes she just ran straight over her #baby! Good thing they don't mind.
More messes! I marked 6 eggs here, 2, 1, 3. Not sure about the double on the first one, I thought it looked too big to be just one #egg.
Weird! Her vulva must be further back than usual.
The food is thickest at the edge, so maybe she is where she wants to be now! She is moving, even if it's incredibly inefficient.
The worm came back in the mean time to deposit two eggs! How kind of her to stop by the stationary camera to do it.
A good stick impersonation for you, WEBs!
No idea! Though I don't think anything so elaborate is going on, just that not all the mutation data was input along with the videos.
#dumpy with an #egg laid at 10s.
Hi @ElisabethB!
#clutch #egg 3 laid all at once, one frame nothing, and then suddenly all three eggs! Most times they squeeze out one after the other.
Little #dumpy laid an #egg at 4s. This one's not an ELD, unspecified type.
This worm lays in twos! Three old pairs, two new ones at 26 and 34. #egg
It's a #double double egg laying! At 1 and 9.
I count three new eggs at 1s, added to the massive pile already laid before.
Long and slender, the polar opposite of the cute little dumpy worms.
@stonepenny was here first! Nice 1 + 2 #egg laying.
Looking back a few videos, this baby's been around for a while. They do hatch relatively quickly, neat timelapse: http://y2u.be/xzgJlsqZpJQ
It's a big bubble. Big enough that the camera prefers it to the worm, unfortunately!
Just resting 😃 See her move around a little later: AWS0000wqh
http://dev.biologists.org/content/129/1/221/F1.expansion.html Pretty pictures!
small bulge visible. No egg laying activity between then and now, and the bulge has gotten much larger! Eggs stuck in a protruding vulva?
I'm really not sure anymore, the bulges vary in size over time on an individual worm. AWS00017df Same worm laying an egg earlier, with a
I think you're right! Remember to mark each egg that you see being laid, even when they're laid all together.
Wow! That's a lot of action at 22. #live-birth #baby in that mess? It looks like the baby goes back under the pile of eggs/mom.
Examining her offspring. 😉 (They don't have 'eyes')
Changed your mind WEBs? 😉 I took a look around, no baby sign before this, 2 videos after there's a baby underneath that escapes. AWS0001973
Lots of old eggs here next to the worm, but I don't see any new ones.
Exactly what it looks like, a big blurry smudge. 😉 Something below the petri dish, maybe, that's out of focus.
An odd #egg laid at 28, quite far back from the normal vulva position.
once they get close to hatching. It's a bit of a pain, but regs are regs... 😄 😄
Obviously if the worm doesn't sign the privacy disclosure, we're not allowed to photograph her children, so any eggs have to be blurred out-
A very accurate name, though not a very kindly one! Poor dumpy darlings. They do seem healthier than a lot of the variants we see, though!
https://www.youtube.com/watch?v=xzgJlsqZpJQ
Maybe, the video isn't high enough resolution to really see what's going on with the eggs. You may like this... probably want to mute it!
A tricky one, she's built up a big file of food and it's distorting our view. I think it's a clutch of eggs, blurred into a wide blob.
even more #stubby
More #stubby!
#stubby
X starts. Z for eggs... Large fingers? 😉
Just because there's a lot of eggs laid already doesn't mean she's done!
The camera is trying to get away from the edge, but it's just too interesting! #glitch
#egg at 29, sneaking in just before the video ends.
Check out figures 4 and 6! http://jcs.biologists.org/content/115/4/857.figures-only
There are at least two groups of mutations that cause morphological defects, Protruding VuLva (Pvl) and abnormal Eversion of the vuLva (Evl)
Luckily the camera isn't fooled by such shenanigans! If they want to lose the camera they have to find something bigger/higher contrast!
It does look like there's an egg laid early on that stays stuck for a while! I confused it with the impacted egg coming in and out of view..
too large to be a single egg stuck. On my list of things to look up now!
I'm starting to doubt if all of these are impacted eggs.. sometimes it seems like it may be a deformity of some kind around the vulva,
The man in the agar. Forever trapped, forever watching worms lay their eggs...
They do 'rest' sometimes. She does start moving after a few more clips, though not very energetically.
They can 'smell' the food area to get back, no lost worms. The cameras are another story!
I love the stubby ones! Direct counter to the long and slender elegant worms, they're just cute 😃
Hit the goal again! A bit after British Science Week came to a close. 😃
PS we are now 62% done.
I knew I recognized this one!
Looks like more than one to me. The pile of eggs already there makes it hard to count the new eggs.
If you have further concerns with the legitimacy of the science coming out of the platform, I suggest you contact the creators directly!
https://www.zooniverse.org/publications
project papers for any project that has published work. They've all dealt with these kinds of questions, successfully.
Now there's a question I can answer definitively. There is a lot of literature. Check out the 'Meta' section at the bottom. Or any of the
First person to see this video, but definitely not the first one to see this worm with her little #baby hiding underneath.
Shedding a chunk of... lets call it #egg-debris? between 19-23. Might be one egg in the mess? Not laid then, but finally getting unstuck.
They must have found the invisible worm with the invisible eggs. Gotta get out your x-ray glasses? They'll work on recorded video, right?
The camera doesn't even budge! That bubble is just too exciting.
C. elegans is actually used in studies relating to longevity. 😉
The worms are manually inspected when put on the plate, to determine which side the vulva is on, sometimes they get it wrong. Not often!
Busy worm! This is a nice example of what egg laying looks like compared to food clumping up, too, since she's in a thick area of food.
That's neat, it does look like the same egg is remains stuck. I wonder the impacted egg will get jostled free after a few more eggs laid?
subjectivity in the classification, there is or there is not an egg laid. Any improvement of each person through 'biased' learning is good!
You don't seem to understand, the entire purpose of this forum is for people to get assistance in learning how to ID the videos. There's no
When eggs like this are laid it looks like a normal egg laying, but then it moves with the worm. If you see that, mark it!
It is an egg, and it is stuck! I can see the little bump of the egg at the start of the video, so I wouldn't mark this as a new egg.
You've found one of the frantic button mashers on talk! Unfortunately they seem to only communicate in hashtags and.. Finnish, I think?
3 #egg layings and quite the clutch of eggs laid earlier at the top! They don't always sit still forever on big clutches!
This bubble is becoming a common sight! I wonder how many videos there are, staring intently at it.
-data analysis. I'm simply a volunteer helping out, so all my 'evidence' will be anecdotal from my own experiences.
I understand it quite well. I can't answer your question about controlling for possible classification biases, as I am not involved in the -
Earning her title as an egg laying defective! Double #clutch laying, 3 eggs each... I think.
And I don't think you've done that many yet! (You're getting there, I know. Maybe in a month? 😃 )
Not the repeats! Very weird, the only cause of repeats I know is when a user has seen all the 'active' subjects. There are 20000 active--
Kinking, twitching, coiling, this worm has it all. Still managing to move around quite a bit with all her issues, though!
It was not, but interpret how you will... It was an offhand compliment to @WEBs, who spotted the same egg I did, in this very messy video.
It would be interesting to hear what @aexbrown has to say about it. As a user, it really doesn't effect my classifications.
A 4 #egg #clutch at 7. Messy but countable!
Multiple #egg layings into an already massive clutch of eggs.
My 200th egg laying video! Well, more like ~210th, as I didn't save the first dozen or so when I started. A nice personal milestone. 😃
The tracking software has taken a little vacation here to wander all the way from the worm on the food spot to the edge of the plate.
0 eggs. Only mark when you see the eggs being laid.
A much larger source bias would be from 'super users.' I don't have the numbers but I guess ~20% of the classifications come from ~10 users
know that there is going to be an egg laying event in the video. I watch videos without any previous markings just as carefully, though!
Hmm, a small bias? There are perhaps 4-6 people I recognize while classifying, and I don't classify those videos any differently, I just -
Leaning on their keyboard? We don't know why users mark 100+ eggs, but they are easy to filter out of the data, so don't worry about them.
They are definitely eggs, not a food pileup. See AWS0000wpl for when they were laid, this worm sits on this pile of eggs for a long time.
#egg 19 One of those times previous marks are nice. When it's someone you know is a zealous egg finder it's worth it to pay close attention!
3 #egg laying events, starting at 17. Curiously small eggs, not nearly as obvious as most.
Another stealthy worm, laying small eggs that blend in very well! I count five #egg laying events, 2 clutches of 2 and 3 eggs each.
That's a big egg for such a little worm! #egg at 12
I had to slow down to answer all the questions! There were 3000+ people on the project during British Science Week. Quite the rush!
Need more space, see discussion! @aexbrown it would be great to hear your opinion on what is going on with this poor worm.
Congratulations! You're catching up to me in a hurry, WEBs! 😄
The outlining software's confused by the pile of eggs and can't figure out what end of the worm is the head, it's switching back and forth.
Yup, the edges of the dish confuse the tracking software if the worm wanders too close to it, it ends up stuck staring at the edge.
Yes, the little one is hiding under mom.
It's a baby worm. Sometimes they like to hide out underneath the adults.
There is a baby worm hiding under the adult, the little 'bubbles' are moments where it partially wiggles out from underneath.
A lovely video if I do say so myself. 😉 Looks like you have a good grasp on worm watching already!
Stealthiest egg layer ever! One #egg at 20s, I nearly missed it.
This sounds like an odd issue... Can you please try switching browsers to see if that helps?
Camera lost the worm and we are now staring at a bubble. Bubbles, sadly, do not lay eggs.
Quite the dancer, she's got those pirouettes down to an art! It's nice to see some elegant movements highlighted, thanks for sharing!
Agreed, looks like a neat single egg at 22. Looks rather odd after the worm wiggles it free, maybe just because of all the churned food?
Those are more babies! Two I think by the head, one or two by the tail, and the 'lonely' one that's gotten away from the pileup on mom.
No eggs, we're seeing the food layer clumping up around the worm here. Check out the videos in the Help and Guide if you haven't already!
The movements around the worm are a baby hiding underneath! If you haven't already, check out the Help and Guide for some clear egg laying.
#dailyzoo for a very bizarre worm!
What a worm! 3 eggs laid, first one at 3 is #impacted, then releases at 10, and then she lays two more at 11, the last egg also impacted.
Looks impacted, a big enough lump that it's probably more than one egg stuck.
Yes, there are some overeager classifiers among us. The best thing you can do is to mark accurately!
The worm just isn't moving enough to leave the eggs behind. These are old eggs, and shouldn't be marked.
You're right, this is a baby hiding under mamma worm.
You can read more about the hardware and software used to create the videos here: http://bit.ly/1Btdy69
You're right, it is backwards. I'm not sure what causes the software to get confused about the head/tail, I've seen it switch mid video--
Short version. 😉 If that wasn't clear let me know and I can clarify in longer than 140 char form.
-logged in users, and it was apparently causing enough exasperation and confusion that they stopped displaying them. Before my time here!
The code speaks! 1) Get random person from egg timings. 2) Display timings if not an anon user. Anon users mark even more non-eggs than-
You're right, eggs come out near the red dot in the middle, the vulva. All the eggs here were laid earlier and shouldn't be marked.
Yup, a very stealthy egg, didn't notice it first time until the worm passed it. You can see it a little near the head at the start, though.
@WEBs_in_space I have found the mysterious 'netherworld layer' 😉 She has a mild twitch but otherwise healthy looking.
That's quite the egg laying session! Nice catch 😃
Yup, could use a quick cleaning!
from all the old tracks, but has stayed stationary with her large clutch of eggs, maybe tired from all the egg laying.
The worms are recorded for 15 minutes, making 30, 30 second videos, so you can see the same worm multiple times! Looks like she was active-
Yes, it's caused when an egg gets stuck in the vulva on its way out. Another type of 'egg laying defective' behavior.
PS if I've skipped a question you want answered, just give it a bump. I know I miss a few coming back to 15+ hours of messages.
And probably loving it! Their natural habitat is soil, they are used to navigating through 3 dimensions, not just a flat plate.
So she might be going for an explore, but probably won't lay any eggs while outside the tasty drop of food. 😃
Neat fact: They prefer to lay their eggs in areas of higher food concentration, so that their offspring have a higher chance of survival.
When the worm is in a thicker area of food it can be hard to see what's going on! You're right, no eggs here.
Correct, only mark newly laid eggs.
Neat! So the camera, worm and the agar medium, were all just cooperating perfectly to get a nice clear shot 😃
You are now officially as worm crazy as me. 😃 There are at least 30 videos of each worm, sometimes more I think... so some get familiar!
Correct, we do not mark eggs that were laid before the video starts, only new ones!
Not a baby, it looks like a crack in the food layer.
You're correct, no new eggs here. She's sitting on a pile of previously laid eggs, we don't mark those.
I am having trouble counting how many eggs were laid here! Three big clutches on top of at least one clutch from before. #dailyzoo
You're the correct one! Some people seem to get excited whenever they see an egg...
Just a confused camera that's lost it's worm. The worm on this plate is roaming unwatched, bet she's up to no good. 😉
If you are curious about this behavior, you might like to read this: http://talk.wormwatchlab.org/#/boards/BWS0000003/discussions/DWS00001s0
She seems to want to ask us something. 😄 If only there was an egg to dot it!
She's inaccurately marked, notice the vulva marking is on the wrong side, the head marker is on the wrong end, too. It happens occasionally.
Some small speck of dirt or dust, normally the plates are kept super clean but sometimes a bit of debris makes it in.
Classification tip! Speed up classifying these sluggish worms by clicking and dragging the progress bar to play through the video faster.
A very short worm! They come in all sizes.
it loses the worm entirely because the worm left the food area and went wandering close to the edge of the petri dish.
Yup. I believe the camera focuses on the highest contrast thing in view, and is initially centered on the worm. In AWS0001fqc you can see-
All our worms here are hermaphrodites, so technically 'it,' but there are also pure males, so calling them she seems appropriate. 😃
Yes, these were all laid previously, no need to mark. Coiled worms that sit on their eggs are the hardest to figure out!
The coiling behavior is caused by a few of the genetic mutations these worms have. Curiously, most coiling worms lay eggs just fine.
Most people do get it! The interface shows you if anyone else has marked an egg, even one person. The majority get it and don't mark them.
I'm not sure, maybe some dust. For scale, the worms themselves are only 1mm long.
You can always go back! Clicking the video restarts it, you can also drag the blue progress bar around to any time in the video.
'Outside' is off the spot of food. She can tell there's nothing tasty out there.
Nice and clear egg laying!
There are two old eggs here, a lonely one in the bottom right, and one still in contact with the worm's tail. No new eggs.
The bump near the tail is just the background food clumping up, note how it's where the worm touches the dark trail in the background.
You are correct, we only mark when new eggs appear.
Please mark these! Egg laying is when the eggs appear near the red dot in the middle, check out the Guide and Help for more examples!
You're correct. 😃 No eggs here, whoever marked it just made a mistake, no worries.
Yup! The crazy high egg markings are actually the easiest to filter out, as there's no chance it's real data.
Correct, no eggs laid here.
It's a bit of the food medium going over top of the worm, it'll work itself free as soon as it moves a bit more. Lots of eggs, none new.
These were all laid before the video started, don't mark. Check out the Help and Guide through the main interface to see some eggs laid!
and also look for any sudden changes that might be a new egg.
These are all old eggs. It is tricky to see when there are so many! With videos like these, I compare the egg piles at the start and end,
You can replay, until you click 'Next Worm.' If the keyboard shortcuts don't work, you can click the 'Egg Laying' button below the video.
It failed to properly lay the egg, so it has an egg stuck half out. The dotted thing is probably dust, the worm didn't like the feel of it!
Little larva! The worms are on the plates long enough for some of the eggs to hatch, and we get to see the babies wandering around too!
Egg laying defective worms sometimes lay eggs in a #clutch like this, try and mark each egg if you can count them.
The egg is #impacted, the worm hasn't properly released it. Mark these only when you see it being laid, same as a normal egg.
These are all 'old' eggs, laid before the video started. New ones come out with quite an obvious 'pop'!
Ouch! Looks like multiple eggs are #impacted here, that can't be pleasant. You're correct not to mark any eggs in this video.
Yup! It looks like it might be #impacted, as it moves with the worm.
Just focus on making your own classifications as accurate as you can!
Don't worry too much about those mistaken classifications, it shows even when only one person has marked an egg, so they do show up a lot!
That doesn't look like an egg stuck to her tail, but I'm sorry to say wormy poos are too small to see. @aexbrown Any ideas what this is?
These are eggs that were laid before this video, the worm has moved since they were laid, and finally leaves them behind in this one! No poo
Baby worms! One on the right, and one that's underneath the parent worm for a while. They go over/under each other, fairly normal behavior.
'User has marked X eggs' shows up even if only one person has marked it, so we see all the mistaken marks. Don't worry too much about them!
Yup! Some worms will lay large clutches of eggs, some are rather lethargic and stay in the same spot. When combined we get a mess of eggs.
No eggs here, just clumped up 'food.' It does look almost like an egg laying, though, good eyes!
Four egg #clutch laid at 23.
-people that get it right, so the occasional overzealous marker doesn't mess up the data!
Welcome! You're off to a good start! Don't worry about the videos where people have marked eggs and there weren't any laid, there are more-
#dailyzoo for weird and wonderful behavior! Worms go 3D!
A few too many links to fit into a little comment! Continued the science discussion!
Check out this video of a worm entering a crack in the food to see one from a different perspective! AWS00013pb
The worms are actually incredibly flat! Their natural habitat is soil, so they're used to more chaotic conditions than a petri dish.
Large clutch of eggs, one laying event at 26, I think 3 eggs but it's hard to tell when there's a big pile already there!
Take a look at the two videos before this one AWS00013pb AWS00013pc There's a crack in the food layer and it crawls in. Very cool!
I think this guy is underneath/in the layer of food instead of on top? At 11 seconds it looks like it pokes its head out onto the surface.
Surprise worm! Nothing in view initially but it shows up at 12 and the camera goes back to tracking.
That's a little baby! Actually not so little, it looks rather large, must have been laid very early.
No egg laying here! Only mark when you actually see a new egg popping out of the side of the worm. What a mess here, though!
Is there is a hole(made by the worm?) in the food here? Looks like it manages to get under the food layer for a little bit.
Four eggs laid, 6 eggs already there, one wiggly larva, and I think one more hiding underneath mamma worm. A very busy worm!
Three eggs in a clutch. Two eggs laid at once looks pretty normal, but more than that and they look like they're vomiting out eggs!
You can see the two eggs clearly at 20s, at 23s the worm has both of them stuck to its side, they vary in visibility after that. Very messy!
I don't see an egg laying 😦 I see four eggs already laid, two clear ones in a pair, and two in the mess the worm is making in the food..
That's a tricky one. I think it might just be the pile of food, would have to see the next video to see if it leaves an egg behind...
Live birth sure looks uncomfortable for these guys... #dailyzoo
Something stuck to the worms tail? Looks a little too long to be an egg.
That's odd. I just got this one, and didn't see any previous timings for it.
Correct! You should only mark eggs when you actually see them being laid.
Lost the worm at the end of the video as it wanders too close to the edge of the plate.
Very funky looking trails from this worm, caused by the slip-sliding sideways motion that erases old and new trails alike.
Taking a slow straight wander #outside
4 individual eggs laid. Hi @2ndgm!
Wandering just #outside the food, reverses at the end and finds the food again.
3 videos with an egg to the bottom right, 4 eggs stuck to the worm, and the worm not moving much. After the 2nd one I went 'wait a minute..'
It's like she's teasing me! 😃
I've seen 3 different videos of this little guy laying there with these eggs, and STILL haven't seen the one where she actually lays them.
Hey Els! Fancy meeting you here! 😃
Five(?) eggs laid, two pairs and one(?) just before the clip ends, can't tell if it's another double or just the one.
What a mess! I don't see any egg laying going on here, all the action happened before this video.
Welcome to worm watching! You're off to a great start.
4+ eggs all laid in a clutch.
stealthy #impacted egg laying, also hi @2ndgm! First time I've seen a name I recognize from talk as a 'previous timing'
I think I caught all the egg laying action here but what a mess with so many eggs already there with a kinking worm in thick food!
I think I see an impacted egg at the start of the video, the baby worm erupts from it, and then the egg slowly deflates over a few seconds?
What a sweet little worm, cuddling the eggs! I know it's just random behavior and getting a little stuck, but still! #dailyzoo
Someone got up on the wrong side of the bed today. #egg laid on the side opposite the red dot.
No eggs here. The gel the worm is moving on is a bit thick here, it confuses the edge-finding when there's clumps of it piled up.
