'''Cymothoida''' is a suborder of isopod crustaceans with a mostly carnivorous or parasitic lifestyle. It contains more than 2,700 described species in four superfamilies. Members of the suborder are characterised by their specialised mouthparts which include a mandible with a tooth-like process which is adapted for cutting or slicing.<ref>{{cite web |url=http://bioteaching.com/tongue-biters-and-deep-sea-giants-the-cymothoida-crustacea-isopoda/ |title=Tongue Biters and Deep Sea Giants: The Cymothoida (Crustacea: Isopoda) |author=Srour, Marc |date=2012-07-13 |work=Teaching Biology |accessdate=2014-06-03 |archive-url=https://web.archive.org/web/20140606205614/http://bioteaching.com/tongue-biters-and-deep-sea-giants-the-cymothoida-crustacea-isopoda/ |archive-date=2014-06-06 |url-status=dead }}</ref>
