This site also had several sheep crabs crawling around the laminaria-rich sandy bottom. Laminaria is a common algae found in Catalina, which has long leaf-like blades which create nice coverage camouflaging a wide variety of marine life including the sheep crab. The sheep crab is a large crab (I often see them exceeding two feet in length when accounting for their large legs) and they stand up on their hind legs when threatened. I expect they would not hesitate to attack me with their large claws if I approached too closely. I have probably come a little too close for comfort before, but fortunately, I have a large camera set-up to protect me.
