Bairdi crabs are two of the four species of the genus Chionoecetes occurring in the eastern North Pacific Ocean and Bering Sea. They form the basis of a thriving domestic fishery from southeastern Alaska north through the Bering Sea. These crabs are also marketed under their trade names: snow crab (C. opilio) and Bairdi crab (C. bairdi).
Migration patterns are not well understood; however, it is known that the sexes are separated during much of the year and move into the same areas during the reproductive season.
Bairdi crabs feed on a wide assortment of marine life including worms, clams, mussels, snails, crabs, other crustaceans, and fish parts. They are fed upon by bottomfish, pelagic fish, and humans.
