Green Crab - Carcinus maenas Shell somewhat broader than long with 5 marginal and 3 frontal teeth. The last pair of legs are flattened, but not paddle-shaped. The carapace grows up to 90 mm wide. <br />

 I saw lots of small (40-50 mm) green crabs in the high and low intertidal zones. They were all dead though. They appeared physically intact, so I don&#039;t think they were predated upon. Usually when I find dead crabs, all that is left is the empty carapaces. Not sure why they were dead, unless they were molts. This crab had a red, round, hole/mark on its left, front claw - maybe that played a role in its demise?<br />
