Agree it could well be actinosphaerium

Very difficult to photograph when moving.

Prime candidate for video when they do not keep still!

How large was this? Since it does not seem to have a distinct layer of ectoplasm, just the one bulging water expulsion vesicle, I think this is likely to be Actinosphaerium's little cousin Actinophrys. The latter are mostly 30-100 µm, not counting the axopodia, and the former usually at least twice that.

This one was the largest that I’ve ever seen.
For what that’s worth ;)
