Some... hmmm... sponge/worm/tunicate/filter feeder/???

[Mihai]

I'm completly stumped by the following creatures. They look like two white solid white tubes (about 1.5" in length) that stand vertically on the rock. By the look of the intakes it seems that one is for pulling water and the other one for expeling it (looks like a sponge output hole). Just like for a sponge no part moves/comes in/goes out... They seem to be filter feeders of some sort.

Also, in the second picture (besides the above described stuff) I think there are some barnacles. They look like small beaks pointing up that open ever so slighly when a 5-6 fingered hand comes out, takes a scoop of water (and probably small food) and gets back in. Are they barnacles?

Thanks,
Mihai

I'm calling tunicate, but can't say for sure (could be sponge showing excurrent 'trumpet').
