This old platform has been closed down recently, I think at the end of April. The new platform is under review (after going through beta testing). Hopefully, it'll be ready to be used soon (fingers crossed). Can't wait for that! 😃
It is a Copepod
Hmm, not sure but maybe a blurred Radiolarian colony?
Yeah, it is! Well recognized.
Yeah, that's a #protist we don't classify for this project.
Hmm, not really sure! That opaque center reminds me of a protist , but those blobs around are odd. I wonder whether you may be right 😄 @jo.irisson what do you think?
At first I was going to say confidently it is a Pteropod but after looking at the image in full resolution I realized it rather looks like a Goblet medusa viewed from above with its tentacles to the sides. Not really sure now 😕
It may seem difficult at the first sight but you can get used to what individual creatures appear like in these images pretty soon.
The opaque organism (3 o'clock) is a small #shrimp. There's a tiny #rocket-ship just above it. Then a #solmaris (top mid), a #larvacean (left mid) and two #copepod (right bottom corner and top left c.). Those tiny lines all around are algae or other noise ('marine snow'), nothing to be classified.
It is a very blurred #radiolarian#colony. Notice that halo around the opaque line, typical for rad. colonies.
@suzeroo Hah, I've just classified it, two years later, and decided these are #pacifier#protist grouping together so I didn't mark them :]
@Nayuta_Ito Nope, it is a very big #radiolarian#colony, to be found under the 'Ribbon/Elongated' categories. It's a bit blurred but you can see individual radiolarians joined together, surrounded by that opaque 'halo'.
Radiolarians live in CAL as well but the researchers are interested only in their colonies for the CAL project unlike in MED where they want them to be marked. Hope it makes sense (Not sure what protist is displayed here though).
Hah! It is my favourite "top" view of a #Larvacean and its #house - the white-opaque walnut-like structure are the house filters, the larvacean is convoluted and we can see mostly its hammer-like head. Helpful? 😃
Well spotted! 😃
It appears opaque (white) on our pictures. Unlike he swimming bells that are usually more transparent.
Can you see that "nose-like" structure - pointy front on the right? That is a pneumatophore, a gas-filled float, typical for Corncob type of Siphos. If you see it, it is a Corncob!
I love switching the data sets frequently as each data sets provides a different experience and both are quite satisfying 😄 I can't tell which one I love more!
In general, there are images of much better quality in CAL data set but there seem to be less individuals in MED images so they may be easier
I can't remember who came up with that nickname, possibly @JoyKidd ?
Looks like a Medusa (4tentacles) to me
😃 Great side view!
I'd go with a waved Larvacean (heading to the right by its opaque head)
Tomorrow is Friday!! :]
@AvastMH don't take me wrong, it may be a fish! I just can't tell since the shape is unusual. But there seem to be fins.
Yep, a very very cool one!
It is a #Solmaris, very nice catch! And a really big guy for California!
Oh wow!!! #FFF#Copepod for sure. Amazing stuff to see on the Talk today! 😃
It seems to be hit by ISIIS (the imaging system). #Solmaris
😃 It is a perfect image of a house! Nice to see it again!
There is a #morethan4tentacles#medusa in the top right corner, then a bent #Larvacean starting a new #house around itself (top left), and that's it. We don't mark Protists (the left bottom) and marine snow (organic matter elsewhere).
At spawning, the gonad of the female bursts via rupture of the gonadal wall at the specialized spawning anlagen on the dorsal side of the gonad. In contrast, sperm come out of a small hole in the sperm duct on the dorsal side, and spawning lasts several minutes. Animals of both sexes die a few hours after spawning.
I may have misunderstood the process somehow, but this is the image created in my head after reading something about that a few years ago.
They care eggs inside their heads actually, and then, once, their heads explode and they release their babies.... or something like that 😛
😃 good to know!
To me it looks like a blurry Larvacean in a very small house. (Perhaps just a cabin? 😄)
Ah, hope my reply makes sense. Sorry, I'm quite exhausted today.
@WEBs_in_space It's a good question. Unfortunately, even our experts cannot decide what it is 😦 More probable suggestions have been mentioned but we still can't tell. Personally, I think why not but that could be just a coincidental similarity to them.
Hey! Yeah, these Rocket-ships are very tricky! When finding the first one, we were even thinking whether it couldn't be a Squid! 😄 Don't worry. You'll know the next time .)
It is a deformed image. It happens when a plankter moves in a specific direction in comparison to the move of ISIIS (the camera). I guess it could be a Cydippid but may be wrong.
To unclear image to tell with certainty. I can't see any Cydippid-like features there. I would maybe guess a bent Larvacean, but it could even be a piece of a Sipho or a R-S in a tailless life stage, or something completely different.
I guess it is an arrowworm's tail twisted and shown from a side with its head in another frame (if captured at all).
Yes, it is a Rocket-Ship Sipho (we were making differences between round and pointy ones and calling them Thimbles and Triangles, but no need to tell them apart any more 😃)
The tentacles are quite blurry in comparison to the copepods. That means they are in another plane - not close enough to the tentacles. Just an illusion 😃
(And please, don't worry if you make a mistake. Every single frame is classified by multiple volunteers and even wrong classifications are helpful)
Hello @2sakakibara It is just a very blurry Rocket-ship. When you can't tell but you're sure it is something, then just try your best guess - what it reminds you of the most from the available categories 😃 Thanks for your help, happy to see you here!
I can see it better now and I'd keep with my previous answer 😄
It is actually just a tricky Copepod (or similar crustacean) in an escape posture. They've got fish-like tails (on the right), the body is bent (on the left) - we cannot see the head.
Don't know. I wouldn't mark it.
Oh, yeah, they have about the same life stages. Triangles and Thimbles are both just nicknames based on an appearance of various species of Siphos having similar shape. Both nicknames are used for animals of various species. Just to make it easier for us 😃
Hello @tzephariron It is a #Cydippid with its both tentacles retracted. You can find it as one of the Head with tail categories.
It looks like Cydippid tentacles - richly branching creating these fans...
Yeah, these mostly appear quite blurry. This one is extremely crisp and clear! Perfect image 😃
It is an upside-down Solmaris. Oh, and there seems to be a small Copepod just next to it (although probably in a different plane).
Yes, it is a small shrimp for sure 😃
I'd go with a #larvacean. Round head, no fin basement visible, the typical shape, proportions and colouration...
I wonder whether the #arrowworm is feeding on a copepod or just an illusion! It is quite blurry to tell but tagging #behaviour anyway.
I'm not wearing my glasses now but it does look like a Sipho, just not sure whether a R-S or a Corncob.
No idea what it is. I'm afraid it is too blurry and small to be sure 😦
Yes, anytime you can link your suggestions to the main Zooniverse Talk, directly in the Dailyzoo Suggestion discussion thread. And if you even add some caption then there is a big chance to see it on DZ blog soon 😉
Larvacean sounds like a good guess. Not sure it is correct though.
Yes, it looks like a tail part of a Sipho Twocups. Don't be afraid of guessing. It is helpful even when incorrect. Just if there is a big chance the animal will be seen in a neighbouring frame and you see too little to ID, it is OK not to mark it.
I would guess a shrimp too. But not very clear.
Oh, I haven't seen any like that for ages! Beautiful creatures.
Yeah, tell me about that! My skills are not what they used to be too. I should spend more time by classifying again. Lets make it a challenge! 😉
I would rather go with a small R-S (heading to the bottom left). Not an easy one!
It is a bottom view of a #Larvacean#house (with the occupant inside). Can you see the two trails? It is the back of the house.
Cydippids are partially opaque and have got two branching tentacles unlike Rocket-ships.
And there is a tiny Cydippid just below, overlapping the doliolid's tail with one of its own tentacles. Can you see it? 😃
Yep, there is a Doliolid with tail. The tail is actually a stem with budding little doliolids (they could be of various sizes). Sometimes only the stem is visible with no buds. Then we classify them as no tail (as seen in the Field Guide)
Hope that helps 😃 If not, keep asking.
Easily said, one swimming bell with a single branching tentacle (although the branches may not have to be visible like in the one above) is most usually a R-S.
They are closely related to Twocups and in some life stages they can be easily confused. I made a montage of Thimble R-Ss and Twocups from various angles to compare. Check them out here: DPK0000bkd
One type has round swimming bell, like the one above. They remind of a thimble, which was actually their project nickname. Swimming bell of the other type is pointy, so we were calling them Triangle.
It is a damaged Radiolarian colony. It has lost its shape but you can still see the pattern of individual bodies and the halo going around them.
Yep. See my other comment.
Yep, it is a small Rocket-ship. There are more types of them. At the beginning of the project we had two categories for R-Ss but then we decided to merge them in one.
Not sure here either. I would go with an overlapping of a Protist with something 😉
All three are Rocket-ship Sipho. As for the top guy, it is in a life stage with multiple swimming bells. Check out the life cycle below:
I wouldn't mark these either. They may be either a protist or a medusa/solmaris, but both look more protist-like to me too.
I'd go with solmaris here or with a morethan4 medusa.
Yep, no doubt it is a copepod - its antennae.
Yep, when it is an unclear margin object which can be possibly recognized from the neighbouring frame, it is better not to mark it.
I would mark the top two and the bottom one for sure. The one between is unclear and possibly a fourth Doliolid. We can't be sure though.
I can see a Larvacean overlapping a spiky protist there.
Looks a bit like a bent Larvacean
The shape doesn't remind me of anything we classify and it is unusually opaque. I wouldn't mark it.
There's a medusa morethan4, arrowworm and radiolarian colony. There may be a tiny transparent L. house next to the colony and a larvacean. Not sure though.
Well, there's a larvacean house with a larvacean in (the right margin), the top guy may be a copepod from a weird angle (just guessing here)
Not sure. The central object reminds of a pacifier protist but what is that mucous matter around/behind it?
Sorry to hear you were spending time by something which is not needed. Feel free to tag whatever you think should be searchable. Just saying it is not needed for PP to use tags. It may be different for other projects though.
So anyone who will search arrowworms could get this picture as an example. It would be helpful if you removed the # symbol from your post 😃
The search is rather a tool for the volunteers who want to see how arrowworms look like from various angles. Now you used a tag for Arrowworm as an example although there is none present in the picture.
It won't show them all. It will show only the tagged ones. And there is a limit for the Search results so even if you tagged every single one, there would be too many results to show them all.
No idea. I wouldn't probably mark it.
Yeah, they can be very tricky!
There's a Radiolarian colony and a blurry object which reminds me of a small Corncob. But I'm not sure I would classify that.
No need to hashtag. In PP the researchers don't need any hashtags for the results, they don't work with our comments. I'm sure someone else will mark it in the classification 😃
It has no key features of the plankters we classify. I think it could be a decaying organic matter. Nothing to be classified for this project.
I wonder whether it might be a Copepod in a jump posture from a weird angle. Just thinking aloud.
This is a head part of a #Shrimp. You can see the antennae (at the top) and some legs (on the left). You'll become able to ID them even from such small parts after seeing more pictures 😃
We only mark the margin ones when we are sure what they are even from the small visible part.
It may be anything. We can't say what it is from such a small part. Don't worry about such small parts of plankters who may be classified from a neighbouring frame. (These frames are actually parts of a much bigger picture.)
It is a Rocker-ship in a life stage with two swimming bells. Check out the life stage cycle:
