Distribution and Reproduction of Shell-Less Opisthobranchs from South Carolina
Abstract:Twenty-three species of shell-less opisthobranchs, including 2 sacoglossans, 10 dorids, 1 arminid, and 10 eolids, were collected from December 1975 through December 1977 in North Inlet Estuary, South Carolina. Twenty-one of these species were new to South Carolina and three (Anisodoris prea, Ancula evelinae, and Berghia benteva) were described from living specimens for the first time. Six northward and five southward range extensions are given. Thirteen species produced pelagic larvae and one species produced capsular metamorphic offspring. Nine of the pelagic species are believed to be planktotrophic and one lecithotrophic. One other species had both pelagic (planktotrophic?) and capsular metamorphic young. The species were approximately 70% West Atlantic endemic and 30% amphiatlantic.
