Help identifing please

I think this is is Metacineta.It is difficult to identify because we see it from different angles.

Hard to make out from a 160px x 200px image. A little larger might help. (As well as some subject size information).

You might also want to consider Hedriocystis brachypous.

It is anyway a suctorian, but a larger micrograph might indeed be more helpful.

Thanks for the reply Charles and Ferry. I'm new here and I don't quite know how to upload a photo as large as the ones I see. Can I get some pointers? I'll try again with this upload.

Given the general "polygonal" appearance, and the fact that the tentacles appear to be protruding through the enclosed top of the lorica, I can see why you are thinking of Metacineta. We only have one view of the cell, here, and no sight of either the stalk or the radial slits in the lorica that are supposed to be characteristic of the family. It is hard to get a sense of the real structure of the creature. I've never seen this suctorian, and am in no position to "fill in the gaps," interpolating structures we don't see. Maybe someone else will recognize it as an old friend.

In any case, there is an excellent, remarkably thorough revision of the genus by Jürg Rieder...87 pages, w/ many illustrations. Perhaps it will help: http://www.sciencedirect.com/science/ar ... 6585800646

The stalk may be hidden behind the body?? That is partly what I meant about seeing it at different angles. Thanks for the reply Bruce.
