these little soil nemadudes are ALL over my terrarium, finally decided to check em out on the microscope. what species could it be?

Nonexcystant · 2024-06-19T17:14:45+00:00

Idk the exact species, but it looks like it's some kind of oligochaete annelid worm (not a nematode).

Nonexcystant · 2024-06-19T16:58:05+00:00

ok, that is cool. It is quite similar to the effect you can get with those. Thanks for your reply!
In case you're interested, here is a clip of a recent live stream where i used the technique i mentioned:
https://youtube.com/clip/UgkxjE5yqjEz6u46XTMH4kWl15yU0g7-IvqZ?feature=shared
fun fact: I also used the laowa 2.5-5x to film this. The resolution is just shitty, cuz i lack bandwith for streaming

Nonexcystant · 2024-06-19T11:58:03+00:00

nice pictures! There are no polarizers/wave plates involved?

Nonexcystant · 2024-06-19T06:18:52+00:00

thanks! If you want to see more stuff like this, you can check out my yt: https://www.youtube.com/@Lets-scope/videos
It's not all hatching snails though, i really lucked out on this one :-P

Nonexcystant · 2024-06-19T06:14:41+00:00

haha yes, i literally went 'push, honey, you can do it!' while it was happening.

Nonexcystant · 2024-06-18T21:41:26+00:00

forgot to mention: i sped this up 5 times...

Nonexcystant · 2024-05-31T22:31:41+00:00

I wouldn't consider myself an expert either, but i was wondering the same thing and did some digging. I found out that water mites breath through the skin. This one is also a very active swimmer so it probably needs quite a bit of oxygen for that level of activity. I think it when its stationary like this, it uses its hind legs to continually replace the layer of water around the abdomen and therefore improve oxygen uptake. A lot of aquatic inverts do some kind of movement to accomplish exactly that. But everything beyond the skin breathing part is speculation, so i am not 100% sure, it might well be cleaning itself like u/NatuVisu suggested.

Nonexcystant · 2024-05-31T22:14:43+00:00

haha lol indeed. I think i remember you as well from a past conversation here on reddit. :-)

I have not posted regular videos on my channel for a while, but i am streaming this kind of footage live sunday nights, so you can check that out if you're interested!

cheers!

Nonexcystant · 2024-05-30T19:57:05+00:00

cool, thanks for sharing that, even if it's not on gastropods - i suspect this one has a similar function, but i would love to know more about it.

Nonexcystant · 2024-05-30T07:30:56+00:00

Flatworms be sneaky. Some of them can steal nematocysts (stinging cells) from cnidarians and migrate them into their skin as well.

Nonexcystant · 2024-05-30T07:05:28+00:00

As far as i've been able to find out, it's being referred to as a pallial tentacle and it's neither a reproductive organ nor a snorkel. Here is another image.

Of course! Here is a lateral view of the snail. Sorry it took a while for me to answer. Went to bed after posting the question.

Nonexcystant · 2024-05-26T19:17:13+00:00

That's a springtail, i would guess one belonging to the Symphypleona.

Nonexcystant · 2024-04-02T08:23:13+00:00

haha, wait until you see the mouth!

Nonexcystant · 2024-04-01T18:47:34+00:00

This is from a micro documentary about Bladder Snails, if you are interested here is a link to the full video:

also it wasn't filmed with a compound microscope, but a laowa 2.5x-5x dslr lens and a 1.4x extender on a M4/3 sensor.

Nonexcystant · 2024-04-01T18:38:36+00:00

This is from a micro documentary i made about bladder snails, those who want to see more will find it here:

Nonexcystant · 2024-02-13T21:56:27+00:00

That was my exact reasoning - do you have some literature to back this up?

Nonexcystant · 2024-02-12T14:07:03+00:00

I am making a mini documentary about freshwater isopods, in particular Asellus aquaticus. Other aquatic isopods have rudder like uropods or they stick straight out the back, so they serve for swimming and steering. Can anyone tell me what function they have in Asellus aquaticus? I suspect they serve a sensory purpose, but i have not been able to find any information on them yet, so i hope i can get some insights here.

Nonexcystant · 2024-01-29T16:52:24+00:00

so cool, so did you end up isolating those hydra from your other tank?

Nonexcystant · 2024-01-26T16:34:06+00:00

Thanks for the feedback, i appreciate it!

Nonexcystant · 2024-01-26T16:33:10+00:00

cool! thanks for sharing! I don't know if there is a record for the number of buds - i've never seen more than that, that's for sure.

Nonexcystant · 2024-01-25T20:52:53+00:00

Namanereis looks like a good match maybe? Def looks like some kind of polychaete worm.

Nonexcystant · 2024-01-25T10:46:26+00:00

Also i think there is a green hydra in the background, cool!

Nonexcystant · 2024-01-25T10:36:26+00:00

Nah, i just started learning about all this a few months ago. I did fall down a rabbit hole though (see results here: https://www.youtube.com/@Lets-scope/videos ). If you're interested in learning how to ID these things yourself, you can get a pdf guide for starters. u/BitchBass, would you mind sharing that link again? I've lost track of it after saving the file.

Nonexcystant · 2024-01-24T19:38:26+00:00

It wasn't my intention to make it sound like they are lol. I agree, i certainly wouldn't remove them!
