Common Box Crab

Calappa lophos

Common Box Crab

It pulls its broad flattened claws up over its face like a mask, which is how box crabs hide and defend themselves on sandy and muddy bottoms. The right claw is a built in nutcracker for crushing shells while the left works as a cutter, letting it prey on snails and hermit crabs down to about 100 metres.
