Also known as the lined shore crab, this handsome purple and green crab ranges from Vancouver Island down to Baja California in Mexico. They can also be found in the Western Pacific in both Korea and Japan. I photographed this one in the town of Moss Landing in California at Elkhorn Slough. Elkhorn Slough is also a great place for sea otters, sea lions and harbor seals.
