Clinocardium nuttallii

Clinocardium nuttallii

Clinocardium nuttallii, commonly known as the heart cockle, is a species of bivalve mollusk found along the Pacific coast of North America. It belongs to the family Cardiidae and is known for its distinctive heart-shaped shell.

Description

The shell of Clinocardium nuttallii is typically heart-shaped, with a smooth and glossy surface. It can reach a length of up to 7 centimeters and is usually reddish-brown or yellowish-brown in color. The interior of the shell is pearly white, with a prominent hinge and muscular foot.

Distribution and Habitat

Clinocardium nuttallii is native to the Pacific coast of North America, ranging from Alaska to Baja California. It can be found in sandy or muddy substrates, often in intertidal zones or shallow waters. This species is well adapted to withstand the changing tides and can burrow itself in the sediment for protection.

Ecology and Behavior

The heart cockle is a filter feeder, using its gills to extract plankton and organic particles from the water. It is also known to ingest sediment, extracting any nutrients present before expelling the remaining waste. This behavior contributes to the overall health of the ecosystem by recycling organic matter.

Importance to Humans

Clinocardium nuttallii is not commonly harvested for human consumption, but it is occasionally collected for its attractive shell. Some people also enjoy beachcombing for these shells as a recreational activity. However, it is important to note that excessive harvesting can disrupt the natural balance of the ecosystem.

Conservation Status

The heart cockle is not currently listed as a threatened or endangered species. However, like many marine organisms, it is susceptible to habitat degradation and pollution. It is important to protect the coastal habitats where Clinocardium nuttallii resides to ensure its long-term survival.
