Dungeness Crab

The Dungeness crab is a species of crab that inhabits eelgrass beds and water bottoms on the west coast of North America. It is named after Dungeness, Washington which is located approximately 8 km north of Sequim and 24 km east of Port Angeles. Usual range of these crabs extends from Alaska’s Aleutian Islands to Point Conception, near Santa Barbara, California. It is occasionally also found as far south as Magdalena Bay, Baja California Sur, Mexico.

This crabs have recently been found in the Atlantic Ocean, far from their known range, raising concern about their possible effects on the local wildlife. Some Dungeness crabs can also be found as far east as Florida, North and South Carolina and Alabama. Read some more information about this crab species below.
