SE facing beach. Sun going down. Low tide. This little guy didn't want to come out of his shell for the picture! Crawling around under water in a tide pool before I picked him up for the photo.
Hermit crabs, common in the tidepools.
Pagurus samuelis, the blueband hermit crab, is a species of hermit crab from the west coast of North America, and the most common hermit crab in California. It is a small species, with distinctive blue bands on its legs. It prefers to live in the shell of the black turban snail, and is a nocturnal scavenger of algae and carrion.
