''Elysia serca'', the seagrass elysia or Caribbean seagrass elysia, is a species of sea slug, a marine gastropod mollusc in the family Plakobranchidae. Although this sea slug resembles a nudibranch, it is not a nudibranch; it belongs to the clade, Sacoglossa, the "sap-sucking" sea slugs. It was first described by Marcus in 1955 from specimens found in Brazil. ==Taxonomy== ''Elysia clena'' is a species first described from Curaçao by Marcus in 1970. Jensen (1982) determined that it was a junior synonym of ''Elysia serca'', first described by Marcus from Brazil in 1955. This was on the basis of the morphology of the radular teeth, the dorsal venation and biological observations. ''Elysia serca'' also bears great similarities to ''Elysia catulus'' (Gould, 1870), a species with a more northerly distribution, and Jensen (1983) considers that ''E. serca'' may be a subspecies or ecotype of ''E. catulus''. Features in common between the two include the anatomy of the mouth, the shape of the radular teeth and the paths taken by the dorsal veins.
