Cluster Duster? & Sponge?

mtfish · 04-18-2006, 06:18 PM

Is this Bispira brunnea? Best picture possible sorry. They are single fans, about the size of a eraser on the end of a pencil. Clear/white in color. Vanish @ any sign of danger. They look like some pictures I have seen, but are not in tight colonies, although I've seen about 10 total on two rocks.

How about this fellow? I'm guessing a type of sponge? Sorry if the picture is dark. It's fine on my home computer but real dark at work. The creature in question is in the darker area in the middle of the picture. It appears to have two tubes into (or out of) it they are pinkish red and about 1/8th of an inch in diameter. The mass the connect into is nothing spectacular, looks like rock.

Your help is appreciated.

Are the worms Bispira brunnea? Nope. Without taking the worm out of the tube and looking at it though it's very difficult to ID it though since there are a lot of feather worms. These will probably never get much bigger than they are right now though.

The second creature is a tunicate.
