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

latus — Any of lepadomorph capitular plates except paired scuta and terga and unpaired rostrum, carina, subrostrum, and subcarina. Smaller plates in basal whorls below paired latera referred to as lower latera; sometimes all or some absent. Types of… … Crustacea glossary
rostrum — (1) Anteriorly projecting, unpaired, usually rigid median extension of carapace between eyes or ocular peduncles; (2) anterior beaklike projection of valve margins overhanging incisure or notch (Ostracoda); (3) unpaired anteroventral plate of… … Crustacea glossary
carinolateral — Compartment plate of cirripeds located on either side of carina, with radii on cardinal side and alae on rostral side. (Syn. latus (cardinal)) [Moore and McCormick, 1969]. (Subclass Cirripedia): ( ) [Anderson, 1980]. Balanus trigonus: apical… … Crustacea glossary
scutum — Paired plate or valve of thoracic Cirripedia; in lepadomorphs, 1 on each side of occludent margin of capitulum. In verrucomorphs, of two types: fixed scutum, 1 of 4 compartmental plates; movable scutum, 1 of 2 opercular plates [McLaughlin, 1980] … Crustacea glossary
tergum — Arched dorsal part of abdominal somites [Poore, 2004]. Arched dorsal part of each of the anterior five abdominal somites (Fig. 1). (Pl. terga) [Perez Farfante and Kensley, 1997]. Dorsal part of exoskeleton comprising tergites of all body somites… … Crustacea glossary
