ID please Rotifer?

Post by Olympusman »

I think it might be a rotifer because of the "foot" between the rear two spikes.

Hello Michael,
I take it this wasn't alive? Because it's missing a lot of parts for a whole rotifer, but does look a lot like just the foot of Trichotria. Those have two spines at the base, two long toes, and also a shorter spine at the end in kinds like T. pocillum, very much as you see here.

No, it was not alive. I spotted the unusual shape on a 4X scan of the slide and had not seen anything like it before.
Thanks.

Very difficult to know if it is a rotifer
I believe that not
