Porcelain Crab Petrolisthes lamarckii
The flat, rounded body of the porcelain crab allows it to slip easily into small rock crevices to hide. However, if it becomes trapped by a predator or stuck beneath a rock, it can shed one of its claws in order to escape, and a new one will grow over time. This crab’s abdomen is folded under its body, but it can be unfolded and moved like a paddle when swimming.
