Tanner 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.

The life history of Dungeness crab is also well-known. There are several studies of growth rate (e. g., Botsford, ; Wainwright and Armstrong, ). In northern California, male crabs enter the fishery primarily at ages 3, 4, and 5 years. Life History and Population Dynamics of two species of Tanner crab, Chionoecetes bairdi and C.

Tanner Crab (Chionoecetes spp.) Tanner crabs are found throughout the Bering Sea region. Two species are relatively large and therefore are of commercial importance. The Tanner crab C. bairdi is the larger of the two species and is usually encountered in the same habitat as red king crab.

Tanner crab definition is - any of several spider crabs (genus Chionoecetes); especially: snow crab. The scarlet tanager (Piranga olivacea) is a medium-sized American recently, it was placed in the tanager family (Thraupidae), but other members of its genus and it are now classified as belonging to the cardinal family (Cardinalidae).

The species' plumage and vocalizations are similar to other members of the cardinal family, although the Piranga species lacks the thick conical.
