The pelecypods are a type of mollusk that has two shells, hence the common name of bivalves. The shells are hinged together by a ligament that continually forces the shells open. Only special muscles, called adductor muscles, can close the shells together. Upon death, the shell springs open since the adductor muscle fails to work.
