Comments: Eats various marine invertebrates (crustaceans, mollusks, sponges, cnidaria, echinoderms, etc.), few plants; also fish (carrion or slow-moving species). Horseshoe crabs are preferred prey in Chesapeake Bay. Spider crabs and rock crabs were important prey at Long Island, New York (Copeia 1993:1176-1180). Adults forage primarily on the bottom (e.g., see Preen 1996, J. Herpetol. 30:94-96), also take jellyfish from surface. Young feed on prey (e.g., gastropods, fragments of crustaceans and sargassum) concentrated at the surface.
