Should do better on the ID but am rather lost on this one.

Strange ciliated. Good video

Thanks Francisco, it looks a bit like a free swimming Stentor, but the only reference I could find to Marine Stentors was Stentor multiformis ...

Interesting fellow, thanks for sharing.

Thanks ImperatorRex

Just checking my notes again, don't know if it will help with the ID but width is 210µm rather than the 170µm posted on the video.

Nice! It does look like a free-swimming Stentor...or some kind of heterotrich, anyway. As you say, Stentor is typically a freshwater genus, but species do turn up in surveys of estuarine and coastal waters, and three species are included in Philip G. Carey's monograph on Marine Interstitial Ciliates.

On occasion I have found "Stentor" ciliates in Mediterranean waters. I thought, perhaps wrongly, of Maristentor

Thanks Fransisco. Found some info on Maristentor, though not sure it is a candidate.

Thanks Bruce, glad to know it does look a bit like a Stentor :)

Nice catch!
