I'm curious why some parts have color, while others don't. They look like something seen when you split a rock.

I think the creature is essentially colourless, except for the red eyespot, but that there may be coloured ingested material, maybe also coloured metabolites from digested or part digested food.

Hi
if this rotifer has a red eyespot , it can't be C.forficata; but unfortunatly it is impossible to give the right name for this genus if you don't look at the trophus.To many genus look like this one.

Unfortunately, far too late to isolate the trophus. Anyway, would be happy with just genus.
