Some interesting finds

While opalescent and shaggy mouse nudibranchs are fairly common at Haystack Rock, every once in awhile the staff and volunteers find some more obscure ones. One example, which was seen last week, is the alabaster nudibranch. As reported by Steve Grace, a volunteer, "This morning, after several months of searching, I finally spotted the alabaster nudibranch (Dirona albolineata). Its white lines glowed against a dark kelp background, its oral veil undulated in the current, and its translucent body seemed to be lit from within."

Steve also found a Christmas anemone (aka mottled anemone or painted anemone) Urticina crassicornis. While they've been seen at Ecola Point, this was the first one seen at Haystack Rock.

The intertidal area at Haystack Rock is ever changing. Sand comes in, sand goes out. Sometimes we have to look really closely to find some interesting things. How many different types of things can you find in this photo?
