Geoduck is a commercial name, and its species name is Pacific mud clam (scientific name: Panopea abrupta). It is a high-end seafood that is highly valued by people in the Far East, including the Chinese and Japanese. Originating in the North Pacific coast of the United States and Canada. It is known as the "geoduck" because of its large and fleshy siphon. The locals don't eat geoducks, so the geoducks are growing well. But since Asian immigrants began to prey on North American geoducks, the local geoducks became endangered. In 1996, artificial breeding began in the Chinese market.
