sea squirt?

[redchick2]

This picture isn't the best, as it sits in a crevice, but I'm thinking this might be a sea squirt. It is growing fairly quickly and is translucent pink. I ca only see one tube coming out of it, but it is in a gap and very well could have the second tube. My first thought was a sponge, but as it gets bigger, I'm leaning toward a sea squirt. Any thoughts pro or con?

I can't tell from the pics if it is a squirt or not. There really are no cons to having one. Pros would be just that they are really neat.

to clarify the pic, the part of this creature I can see really resembles a smurf head. It seems to be almost a sphere on the bottom with a tube coming out of the top. Occassionally I can catch the the tube closing and opening really fast. The whole thing is translucent pink with a slight darcker color inside it where the tube joins the body. It is growing fairly fast, so I'll try to get a better pic in the next couple of weeks.

It could be a squirt or tunicate, I look forward to updates.
