Thank you very much, Dr. Mann. This is what makes Marine Biology so much fun!
I've been meaning to say for a long time that I very much enjoyed your article on the History of Marine Biology. For anyone who hasn't read it, it's in the group's files section. And in case anyone is interested and missed it (one of our members posted this at some point, and it's so much fun to just browse through the engravings) you can read the Voyage of the Beagle at Project Gutenberg online:
I'm so happy to be part of the group!
Have taken the liberty of forwarding your photo + request to an associate of mine in British Colombia. He's rather good at this type of identification and will let you know any results!

I thought it was a bryozoan of some sort, or possibly a sponge, but haven't found anything that resembles the texture/pores/markings/? on this. Ironically I'm giving a short presentation on the unique difficulties posed by convergent structures in identifying rocky intertidal organisms. (to begin with, just figuring out if it is the proverbial animal or vegetable! *laugh*) So I went to the coast to take some pictures for demonstration.

You can see there is encrusting algae and purple encrusting sponge Haliclona ecbasis, in addition to some other encrusting animals including tube worms. Unfortunately this is the only picture I have. I've tried searching photos of encrusting bryozoans, hydroids, sponges, tunicates. I am not an expert, just a volunteer naturalist who's starting to lose it a bit. :)
