Epicaridea

Epicaridea is a former suborder of isopods, now treated as part of the suborder Cymothoida. They are ectoparasites that inhabit other crustaceans, namely ostracods, copepods, barnacles and malacostracans. The suborder is found globally. About 704 species have been recorded. Epicaridea are generally less well researched than other isopods.
