Washed up shore crab shell

Quite often shells from shore crabs are washed up onto the beach. Occasionally these shells can contain the remains of dead crabs, but they are mostly the result of sloughing. Shells that are a result of sloughing are easily recognized, they are lighter and the carapace is so loose that it is possible to peer inside. To the right is a carapace seen from above, while on the left, seen from below. The example shown originates from a male.
