The Dungeness crab is a type of crab that inhabits eel-grass beds and water bottoms from the Aleutian Islands in Alaska to Santa Cruz, California. They are named after Dungeness, Washington, a town now known as Old Town, Washington or Old Town Dungeness, Washington, which is located approximately five miles north of Sequim.
They measure 10 inches (25.4 cm) in some areas off the coast of Washington, but typically are under 8 inches (20.3 cm). They are a popular delicacy, and are the most commercially important crab in Washington's territorial waters.
