Hexapus is a genus of crabs in the family Hexapodidae. It contains only three extant species found in the Indo-West Pacific. They inhabit the intertidal and subtidal areas of shorelines. ==Description== Like other members of the family, these crabs are easily recognizable due to the complete absence of the last pair of walking legs (pereiopods). They thus only have six walking legs (excluding the claws), unlike the usual eight. Their carapace is subquadrate, wider than it is long, with a rounded anterior. ==Species== The following are the species classified under Hexapus.
