This sea slug superficially resembles a nudibranch, yet it does not belong to that suborder of gastropods. Instead it is a member of the closely-related suborder Sacoglossa. The suborder Sacoglossa are known as the 'sap-sucking Opisthobranchias'. Many members of this group use chloroplasts from the algae they eat; a phenomenon known as kleptoplasty. Elysia chlorotica is one of the "solar-powered sea slugs," utilizing solar energy via chloroplasts from its algal food. It lives in a subcellular endosymbiotic relationship with chloroplasts of the marine heterokont alga Vaucheria litorea. Elysia chlorotica can be found along the east coast of the United States, including the states of Massachusetts, Connecticut, New York, New Jersey, Maryland, Florida (east Florida and west Florida) and Texas. They can also be found as far north as Nova Scotia, Canada. Elysia chlorotica are most commonly found in salt marshes, tidal marshes, pools and shallow creeks, at depths of 0 m to 0.5 m. Adult Elysia chlorotica are usually bright green in colour, due to the presence of Vaucheria litorea chloroplasts in the cells of the slugs digestive diverticula. However, they can occasionally appear reddish or greyish in colour, thought to depend on the amount of chloroph...More: http: //booksllc.net/?id=844026
