The '''Entoniscidae ''' are a family of marine isopod crustaceans in the suborder Cymothoida.<ref name=WoRMS>{{cite web |author1=Chris Boyko |author2=Marilyn Schotte |name-list-style=amp |year=2011 |title=Entoniscidae |editor1=M.

A small chitinised hole develops through the host's exoskeleton through which the isopod can communicate with the environment. The female isopod bears little resemblance to any free-living isopod, but the morphology of the larvae show their taxonomic affiliations.<ref>{{cite web |url=http://www.vims.edu/research/departments/eaah/programs/crustacean/research/parasitic_isopods/index.php |publisher=Virginia Institute of Marine Science |accessdate=August 18, 2011 |title=Epicaridea: the parasitic isopods of Crustacea |author=Jeffrey Shields |archive-date=January 5, 2019 |archive-url=https://web.archive.org/web/20190105043313/http://www.vims.edu/research/departments/eaah/programs/crustacean/research/parasitic_isopods/index.php |url-status=dead }}</ref>
