The green crab is native to the Atlantic Ocean off of the coast of Europe. Around the early eighteen hundreds the green crab was first seen on the Atlantic coast of North America. The crab can now be found from ranging from as far north as Nova Scotia and to the southern state of Virginia. In the late eighties, the crab mysteriously showed up in the San Francisco Bay area, and has since been spotted as far north as Oregon. This crab has also been found in such areas as far reaching as the continent of Australia.(Deegan, et al 1999, Holden 1997)
