Orcutt Naked Clam (Chlamydoconcha orcutti)
…a species of clam native to the west coast of North America, ranging from northern California to Baja California. The orcutt naked clam is not truly naked, its shell is greatly reduced and are hidden inside the bivalves enlarged mantle. For defense C.orcutti has white papillae covering its mantle, these papillae secrete a chemical defense to thwart predators. It also has a very large and muscular foot allowing it to crawl around and be more active than other clams. Like other bivalves it is a filter feeder, and filters the water around it for food particles.
