carina — A raised ridge on the surface of the exoskeleton [Ingle, 1980]. A ridge or keel of the exoskeleton (Fig. 1, 2). (Pl. carinae) [Perez Farfante and Kensley, 1997]. Any keel like structure, as on dorsum of pleon on some amphipods; in cirripeds,… … Crustacea glossary
carapace carina — Narrow ridge on surface of carapace (cf. decapod carapace and stomatopod integumental ornamentation) [McLaughlin, 1980]. Narrow ridge variously located on surface of decapoda carapace named types: a) antennal. Narrow ridge extending backward from … Crustacea glossary
