Calappa (crab)
''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 anthropomorphism, anthropomorphising the way the crab's chela (organ), chelae (claws) fold up and cover its face, as if it were hiding its face in shame. Species There are 43 extant species in the genus: *''Calappa acutispina'' Lai, Chan & Ng, 2006 *''Calappa africana'' Lai & Ng, 2006 *''Calappa bicornis'' Miers, 1884 *''Calappa bilineata'' Ng, Lai & Aungtonya, 2002 *''Calappa calappa'' (Linnaeus, 1758) *''Calappa capellonis'' Laurie, 1906 *''Calappa cinerea'' Holthuis, 1958 *''Calappa clypeata'' Borradaile, 1903 *''Calappa conifera'' Galil, 1997 *''Calappa convexa'' Saussure, 1853 *''Calappa dumortieri'' Guinot, 1962 *''Calappa exanthematosa'' Alcock & Anderson, 1894 *''Calappa flammea'' (Herbst, 1794) *''Calappa galloides'' Stimpson, 1859 *''Calappa gallus'' (Herbst, 1803) *''Calappa granulata'' ...

Calappa Hepatica
''Calappa hepatica'', the reef box crab, is a common benthic species of Calappa (crab), box crab of Tropics, tropical and subtropical parts of the Indian Ocean, Indian and Pacific Oceans and the Red Sea. Description ''Calappa hepatica'' grows to a carapace width of about ; the length is always less than two thirds of its width. The posterior portion of the shell has broad extensions with several blunt teeth on the margin, and these largely conceal the walking legs. The carapace and the exposed parts of the Chela (organ), chelae (pincers) are a mottled greyish-brown colour, and are covered with small raised tubercles of various sizes, making the crabs well-camouflaged when semi-submerged in the sand. The chelae are large and powerful, and specially adapted to the crab's feeding behaviour, the crushing and eating of Mollusca, molluscs. Distribution and habitat ''Calappa hepatica'' is found in the tropical and subtropical Indo-Pacific region, its range extending from the Red Sea to ...
