Saxidomus nuttalli

Saxidomus nuttalli is a species of large, edible saltwater clam, a marine bivalve mollusk in the family Veneridae, the venus clams. This species is native to the Pacific coast of North America, ranging from Alaska to Baja California.

Description

The shell of Saxidomus nuttalli can reach a size of up to 15 cm. It is thick and heavy, with a shape that is roughly equivalve and inequilateral. The exterior of the shell is white to cream in color, often with brown or yellowish patches. The interior is glossy white.

Habitat and Distribution

Saxidomus nuttalli is found in the intertidal and subtidal zones, typically buried in sand or mud. It is most commonly found in estuaries and bays, but can also be found in open coastal areas. The species has a wide distribution along the Pacific coast of North America, from Alaska to Baja California.

Diet

Like many bivalves, Saxidomus nuttalli is a filter feeder. It feeds on plankton and other small particles in the water column, which it filters out of the water using its gills.

Human Use

Saxidomus nuttalli is harvested for food by both commercial fisheries and recreational harvesters. It is also used in research due to its sensitivity to environmental changes, making it a useful indicator species.

Conservation

While Saxidomus nuttalli is not currently listed as threatened or endangered, it is vulnerable to habitat loss and pollution. Overharvesting can also be a concern in some areas.
