Hey Romunov, can you ID this?

I think it is a cuke but not sure... The arms are constantly filtering the water and curling in to the mouth...

I have it in the expert forums but no one is biting....

I have quite a few of these. They are hitchhikers on live rock. It is indeed a type of cucumber that lives in a cavity in the rock. They thrive in systems where detritus is blown off the rocks by the powerhead or turkey baster once or twice a week. I think they're neat.

Imagine my surprise when I read the topic. :D
I was away as well. Field day, been collecting Insects and identifying them. Fun fun. :bigeyes:
