This species is native to the eastern Pacific Ocean.

It has been found at least as far south as 300 miles (480 km) south of the US–Mexico border in Baja California on the Pacific Ocean side, where strong surf sometimes washes ashore live clams.

The indigenous peoples of California used this species for food.

[1] They are mainly filter feeders, and can attach to rock substrates.

They are a brownish- tan color so they blend in with their environment, like sand and rocks.
