That, my friend, looks like some sort of tunicate/sea squirt.

Good stuff...will help filter the water!!

A sea squirt, eh? Hmmmm, okay, thanks for the ID. It seems I have another of this type on another rock, though, it just looks like a translucent tube. I was looking at it wondering what IT was when al of a sudden the mouth of it closed. I was like, holy heck, it moves too!?

Does anyone know how they breed?

[Dell2go]

don't know. hopefully it's good and not bad.

If it is indeed a sea squirt, the breed similar to sponges and some corals. They just release sperm and eggs into the water and the little larvae will attach to rocks and hopefully develop.

The translucent tube could be a tunicate.
