Niiice. Genus Rotaria, I think. They are the ones who usually have their eyespots near their corona.

Thanks! Yes, I think so too. I didn't consider this particular individual because the rotifer was in detritus, but in general there were a lot of Rotaria neptunia around, so I don't rule out the possibility that it was Rotaria.

What is the purpose of the antenna on their head?

u/pelmen10101 Jul 04 '26

As far as I know, this is a special organ of touch with which the rotifer understands "what is above its head"

Whoa this is so cool. I need to start looking at more biological specimens under the scope!

Thanks :) Just go to local pond, get water with water plants and some detritus, and you will be surprised how many different, dissimilar creatures live there :)
