A sea otter at Moss Landing, California, eating what appear to be Mya arenaria. As well as being eaten by humans, the soft-shelled clam is relished by sea otters in the eastern Pacific Ocean, [citation needed] where the clam is an invasive species. In New England the soft-shell clam is preyed heavily upon by northern moon snails and invasive ...
Tivela stultorum, also known as the Pismo clam, 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 eastern Pacific Ocean. As the name implies, the Pismo clam lives in Pismo Beach, California. It has been found at least as far south as 300 miles (480 km ...
Edible molluscs are harvested from saltwater, freshwater, and the land, and include numerous members of the classes Gastropoda (snails), Bivalvia (clams, scallops, oysters etc.), Cephalopoda (octopus and squid), and Polyplacophora (chitons).
Harvesters locate the clam by looking for a "show," which can present as either a hole or depression in the sand. [8] Some clams expose their siphons as the surf is receding making them far easier to spot; this behavior is called "necking". [9] Razor clams are commonly battered and fried in butter. They can also be used to make clam chowder.
The geoduck is native to the coastal waters of the eastern North Pacific Ocean from Alaska to Baja California. [2] The shell of the clam ranges from 15 centimetres (6 in) to over 20 centimetres (8 in) in length, but the extremely long siphons make the clam itself much longer than this: the "shaft" or siphons alone can be 1 metre (3 ft 3 in) in ...
This clam is a filter feeder and consumes microscopic algae such as dinoflagellates, diatoms, and cyanobacteria. [2] [6] Some dinoflagellates produce neurotoxins, such as saxitoxin and its derivates, that bioaccumulate in the clams and other bivalve mollusks and can cause paralytic shellfish poisoning (PSP) when the clams are eaten.
The two species commonly known as horse clams inhabit the Pacific coast intertidal zones: the pacific gaper, T. nuttallii, more abundant south to California; and the fat gaper, T. capax, more abundant north to Alaska. Both have oval and chalky-white or yellow shells with patches of brown periostracum (leather-like skin) on the shell.
Clams in the culinary sense do not live attached to a substrate (whereas oysters and mussels do) and do not live near the bottom (whereas scallops do). In culinary usage, clams are commonly eaten marine bivalves, as in clam digging and the resulting soup, clam chowder. Many edible clams such as palourde clams are ovoid or triangular; [3 ...
