Comprehensive Description

Biology/Natural History: The siphon of this clam is not long (even though it has a well-developed pallial notch) and the clam buries only to 10 cm depth. This clam is introduced from Asia. It was first accidentally introduced into British Columbia in 1936 along with Pacific Oyster spat. It has now become well established and is one of the main species of clam harvested along the coast of Washington and British Columbia. Moon snails Polinices lewisii don't often attack this species because the species lives so high in the intertidal. Breeds in the summer. May contain pea crab symbionts Pinnixia faba or P. littoralis. Tolarates salinity as low as 1/3 seawater. May live 14 years. May contain red tide toxins.
