ID please (cold water)

[ruddybop]

please help me ID this cold water coral/sponge/algae thing. I found them in 18" of water at low tide in full sun.

The first thing I thought is that it looked like a brain.... Check this link out Green...I am far not a salt water expert with my zero salt water tanks that I own...LOL ... Kinda looks like this to me..
