Fieldtrip to 15th St. Public Dock, Newport Harbor, and Reef Point, Crystal Cove S.P., Orange Co., CA, March 29, 2013

sponges and tunicates	Native oysters, Ostrea lurida, were common on this dock.	-
There were lots of both solitary and compound tunicates.	-	encrusting bryozoan

A California sea lion did not seem to be bothered by people. He looked rather thin.	shell of Norris' top snail (Norrisia norrisi)	-

-	I normally only see this bryozoan encrusting shells that already have hermit crabs in them. On those, the bryozoan layers get much thicker. This snail is definitely already infected. I don't know which bryozoan this is and I would like to know.	-
This is what subtidal hermit crab shells of Pterapurpura spp. often look like, thanks to the growth of whatever this bryozoan might be on their acquired shell.	-	The bottom side of a pholad, a bivalve that bores into sedimentary rocks.

-	The tiny Keep's chiton (Cyanoplax keepiana) is always difficult to get in sharp focus. I didn't do very well.	aggregating anemones surrounding a limpet grazing patch
