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 their chela (claws) fold in in front of their face, as if hiding it in shame. There are thirty nine generally recognised species in the genus. Taxonomic sources disagree on the number of species, with some sources classifying several species from the genus Cancer as Calappa.
