Plagusiidae
The Plagusiidae are a family of crabs, formerly treated as a subfamily of the family Grapsidae, but have since been considered sufficiently distinct to be a family in their own right. The family Plagusiidae used to include a subfamily Plagusiinae, comprising the genera Percnon and Plagusia, which constitute a widespread group of litophilic, intertidal and subtidal crabs that are notorious for their speed and their agility.
Six genera are currently included in the family:
