Calappa is a genus of crabs known commonly as box crabs or shame-faced crabs. The name box crab comes from their distinctly bulky carapace, and the name shame-faced is from anthropomorphising the way the crab's chelae (claws) fold up and cover its face, as if it were hiding its face in shame.[2]

There are 43 extant species in the genus:[3]


Extinct species

A further 18 species are known only from fossils.[4][5]
