King Crab

 

(Paralithodes camtschatica), an invertebrate of the family Lithodidae of the order Decapoda. Outwardly it resembles the crab, but actually it is closer to the hermit crab (family Paguridae). The cephalothoracic shell is heart-shaped and equipped with spikes. The abdomen is folded up under the céphalothorax (as in true crabs) and is covered with numerous plates placed in rows lengthwise; the females have asymmetrically placed plates. The width of the céphalothorax in large males reaches 25 cm, the legs extend to 1.5 m, and the weight reaches 7 kg. The females are smaller. The king crab lives in the Sea of Japan and the Sea of Okhotsk and in southern parts of the Bering Sea. It makes regular migrations. Particularly large numbers are found on the western shore of Kamchatka, where the most intensive exploitation is also concentrated. Only the muscles of the legs are used for food.

Embryo development in golden king crab examined in this study was similar to that reported in other studies for the red king crab (Nakanishi, 1987), blue king crab (Stevens, 2006), and snow crab (Moriyasu and Lanteigne, 1998).

Of the 10 species of crab caught all over Alaska, (seven with commercial importance--red king, blue king, golden king, Tanner crab (bairdi), snow crab (opilio), hair crab and Dungeness crab; and three minor species--scarlet king, grooved Tanner and Triangle Tanner), the red and blue king crab have the greatest history of commercial value.
But a substantial number of crabbers survived and pioneered new fisheries -- brown and blue king crab, and the two species of tanner (snow crab) called bairdi and opilio.
