Giant enemy crabs are a rare species of crab found along the Japanese coast, and are thought to be related to the more popular Japanese spider crab. Although they were once fairly commonly distributed along the Japanese archipelago, extensive hunting and planned attacks on their weak points for massive damage have caused the number of giant enemy crabs to severely dwindle, especially during the early 20th century. Giant enemy crabs are the largest species of crab in the world; unfortunately, they are also the most hostile, most laggy and the worst tasting type of crab as well.
