Two very different specimens I need help with

#1 Post by D0c » Mon Mar 29, 2021 3:45 pm

I have no idea where to start here.

After searching through all the websites I have on my laptop My first thought was epistylis procumbens but I don't think it's that. You can see what looks like loricas with something inside them, there seems to be a flagellum emerging from the loricas in video 1. It seems to be branched or stalked and be able to feed and swim changing direction when it needs to. They were small hence the video quality I estimate 80µm.

This is different very large ball surrounded by lots of cilia. Once again no idea.

First one is Dinobryon.

Second is a colonial flagellate algae, maybe Uroglena. (Not my bailiwick. ;))

Excellent I would never have found that. Been reading about Dinobryon, very interesting to read that they reproduce by binary fission as well.

Thanks.

Yup, binary fission (same as all single-celled critters). :)

I think Uroglena is pretty likely for that big colony.
