The crab and the shrimp are summarized as the Decapoda. When distinction of a crab and a shrimp is called something, it is a crab that the abdomen is folded up at the belly side, and it is a shrimp that the abdomen (the so-called portion of a tail) is well developed.
If a scissors leg is extended, the male of a spider crab will exceed 3m and will reach the weight of 20kg. Although a female's leg is short small compared with a male, it still becomes about 30cm of shell length. By endemic species of Japan, it is proud of the size in Arthropods of all the maximum. It inhabites with a depth of water [ 50-200m ] seabed, and carries out seasonal movement. Ashore, he cannot support prudence on thin foot and cannot walk.
