ID?

Post by Donw »

This critter is amazingly thin. As swam, it would 'twist' its body around 360 deg. The part of its body that was 'edge on' would almost
disapear.

Flash, Canon 50D, 2.8X Photo tube.

Good day DonW

I think that your unkown is the ciliate Litonotus sp.

Hi,
It seems to be Loxodes sp.
best regards

Good Morning

I think that this is Litonotus rather than Loxodes because the cilia are most developed on the one side while Loxodes has more ciliae covering its entire surface. Loxodes has a concave mouth area, this specimen does not. I do not see any Mullers bodies in this specimen and usually Loxodes is brown in color rather than transparent.

My thought on the subject.

All the best to both

John

Thanks John!
Thanks Olivier!

I think it could be Litonotus. It has the two 'Circles' (Nuclei?) in it that show up in many other photographs. Definately doesn't have the hook in its nose that Loxodes has.

I observed this guy for about 15 minutes all told, and I never saw it extending its 'neck'. All of the other Litonotus examples I've seen seem to stretch out quite often.

I think I will classify it under Litonotus, unless someone comes up with a better ID.
