Summary

This "grasping pair" of male and female red king crab, Paralithodes camtschaticus, were collected in the shallow waters of Womens Bay, Kodiak Island. They migrate to shallow water to mate or "grasp." The juveniles stay in shallow waters aggregating into huge balls of crab; in Womens Bay these congregations often cling to pilings under a pier. The pods disperse at night, reforming at dawn. Adults are large, males 227 mm by 283 mm, reddish brown to purple, covered with spines. They range from Barrow and the Chukchi Sea (MacGinitie, 1955), the Bering Sea to the Queen Charlotte Islands, and along the Aleutian Islands to Japan. They have been recently introduced to the Atlantic coast of Russia and Norway (Kuzmin et al., 1996). Adults prefer sand or mud bottoms, ranging from 3 to 366 m. Their diet consists of sea stars, urchins, clams, barnacles, and other benthic invertebrates. The largest crab in U.S. waters, the king crab are very important commercially; in U.S waters, they are presently taken primarily in the Bering Sea and in Southeast Alaska.

Scientific name: Greek para (beside, near, parallel) andlithodes (rock like); and Latin camtshaticus (belonging to Kamchatka).
