Stephen, I did a google search on colonial tunicates and found "Encrusted social tunicates" found a pic of what looks very similar to what I've got. Thanks, very cool.
http://www.photoquest.com/traveling_.../travel4.shtml about halfway down the page on the right side appears to be very similar to what I've got. I also found
http://www.habitas.org.uk/marinelife...a/botsch_p.htm which appears very similar as well.
Thanks Doug
