'''Epicaridea''' is a [[suborder]] of [[isopod]]s. They are [[ectoparasite]]s that inhabit other [[crustacean]]s, namely [[ostracod]]s, [[copepods]], [[cirripede]]s, and [[malacostraca]]ns. The suborder is found globally. About 704 species have been recorded. Epicaridea are generally less well researched than other isopods <ref>{{cite book | author =Brian Morton | date = Sep 2003 | title = Perspectives on Marine Environmental Change in Hong Kong and Southern China, 1977-2001 | publisher = [[Hong Kong University Press]] | id = ISBN 9-622-09641-7 | pages = 152}}</ref>.
There is a high degree of [[sexual dimorphism]] within the order. The female is commonly very asymmetrical, often losing segmentation. Two pairs of rudimentary [[antenna (biology)|antennae]] are carried on the head. [[Arthropod mouthparts|Mouthpart]]s show little development, with only [[mandibles]] and maxilliepeds present, sometimes with a second pair of rudimentary [[maxilla]]e. Males are of smaller size than females and of different appearance. Development is through regressive [[metamorphosis]], undergoing two or three larval stages <ref>{{cite book | author = Harriet Richardson | date = 1905 | title = A Monograph on the Isopods of North America | publisher = [[United States Government Printing Office|Government Printing Office]] | pages = 497 pp}}</ref>.
