[MARINE_BIOLOGY_INTERNATIONAL] Re: Identification help?

 

Cindy:

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. :)
