This was on red sponge at a depth of about 20m on the back side of Santa Cruz Island. I hate to admit it, but I did not see it when I took the photo. It showed up when reviewing the pictures of a Cadlina limbaughorum photographed right next to it.
I cannot see enough of this small animal to be certain, but it looks like it might be a young specimen of Rostanga pulchra. It was under a small rock near the west end of Anacapa Island, front side.
