East Coast soft-shell clam with a thin, brittle shell that doesn't close entirely due to the long, rubbery neck (siphon) extending from the body. Steamers are the smallest of the Atlantic soft-shell variety. They are, as their name indicates, delicious steamed. They're also suitable for batter-dipping and frying. See also clam.
