Cuthona kuiteri - update of images

September 20, 2005
From: Bill Rudman

I am posting today an interesting message from Linda Ianiello concerning Austraeolis catina, an aeolid which seems to be associated with a sponge.  I compare it with Cuthona kuiteri, which is also associated with a sponge, but rather than using the sponge for food, it feeds on a hydroid which has a symbiotic or commensal relationship with the sponge. I took the opportunity to upgrade the images I had on the Fact Sheet for that species.
