The Dungeness crab is a delicious crab available in the United States. Dungeness is a port in Washington States, but the range of this crab extends down the west coast of the United States and Canada, stretching from Alaska to California. Typically these crabs grow to 20 cm (7.9 in). This crab is not considered to be at risk in any way, but concerns arise from the fact that they have been found in the Atlantic Ocean, far from their natural range.
