I've never seen these animals. How do I collect them in the middle lane? They write that they live everywhere, but for some reason they didn't catch my eye, I probably don't look like that. It is interesting to observe the living and make some preparations.

Try shoveling a few kilograms of wet moss. wink.gif

At the same time, you know how big they are, don't you? =)

And more. And why did this question arise in a forum dedicated to the life of insects?

Why not? I think this is the right place smile.gif.
Well of courseyes.gif. They are quite large.


Well, probably because tardigrades are not related to insects. It's even a different type of animal.

And" big enough " for what? Here you wrote that you had never seen them, and they never caught your eye. So they can't be seen with any eyes without strong optics. Many infusoria or amoebae are larger in size.

I dare to speak up for Troglodit: I have seen a lot of infusocryas, amoebas, flagellates, rotifers, bacteria and other microscopic animals (of course, my eyes were somewhat superstructured with optics), but never tardigrades. But I confess-I didn't shovel kilograms of meat. And as for the choice of forum, the entomological section is clearly closer than any other, especially in light of the fact that in addition to insects, centipedes and spiders are constantly discussed here, and sometimes worms and mollusks are also discussed here.

This is not important, although it is true. The books are always the same, and which shelf to put them on is a matter of ten. Related groups, methods too. They are large enough to be seen with binoculars. I see hypopuses of oribatids normally, they can hardly be called large.

Has anyone seen any tardigrades?

What meat, Oleg! tfu.. Esox! )))
I found a bunch of tardigrades on my windows, or related animals after I brought steppe moss for the terrarium

How do I know, I could have confused them with someone, ticks can be similar, I won't say exactly what they are tardigrades, but they don't look like" dust mites " either, so they come out in the moss, meat is a dead end)))

Then, probably, the demodexes fell out of you. In general, the speed and depth of degradation of your biological knowledge is amazing. And the most interesting thing is to quote your old words (which you probably forgot long ago, like 99% of everything you knew before): "non-linearity is very large."

I found them, tardigrade jump.gif
At least I think it's them smile.gif
And, tellingly, they recommend exploring moss, but no matter how many different mosses I looked at, there were none. But they were found in the forest floor.
Such small whitish, translucent creatures, like a small thick caterpillar, but the size is 0.3 mm!
Photo alas, it will not be difficult yet.

aren't these some sort of collemballs?.. =)

24.01.2018 11:21, KM2200

Well, no, collemballs are not like that at all (although there were a lot of collemballs there, it's true). They have a well-defined head with whiskers and eyes, they are completely opaque, and they do not move at all.
Tardigrades might be confused with rotifers, but tardigrades have legs.
Also, if you fill everything with water, insects, including collemboles, float up, and tardigrades continue to crawl calmly under water!

But identifying them is a lost cause, even under binoculars. It is necessary to consider claws weep.gif

Why use binoculars? To study such animals, a simple transmission microscope is used, for example, "Biolam".

26.01.2018 10:34, KM2200

Why, why... Because I don't have anything else.

Cool! Take a photo please - you can even try to take a picture on your phone through binoculars, sometimes something can be seen coming out.

I already tried everything, but it didn't work out. I'll try again on the weekend, they still live with me.
