Family: Psammobiidae (Sunset Clams)

Psammobiid clams are generally considered an invasive species in Pacific Northwest waters, generally believed to have been carried in ship ballast water from the Korean peninsula and Japan. All are burrowing suspension feeders, with well-developed siphons. They are now widely distributed in the Northwest and even found in the upper intertidal zone where significant fresh water input is present. The clam is considered commercially to be a "soft-shelled" clam, with an easily breakable shell. Sea birds have been observed to feed by dropping the clams from height, and they are a valuable commercial food product.
