The Grapsoidea are a superfamily of crustaceans from the suborder of the crabs (Brachyura) in the order of the decapods (Decapoda). They live semi-aquatic (half on land, half in water) in both fresh water and the sea. They occur mainly in the tropics, only a few species also live in temperate latitudes.

Systematics

According to the Integrated Taxonomic Information System (ITIS), the superfamily of the Grapsoidea consists of six families. Within this classification, however, only the families Grapsidae, Sesarmidae and Varunidae are monophyletic. Within the Sesarmidae, the genera Chiromantes and Parasesarma are probably not monophyletic.
