I'm gonna go with tunicate.


Try looking here under tunicate or sponge maybe:

kinda blurry try shooting from a few inches further back. Does it move or is it anchored?

get a cheap magnifing glass from drug store makes taking pics way easyer

I think it is probably a tunicate too, but hard to tell from the pic. Possible it could be a sponge.... Looks pretty, nice :D
