Japanese Spider Crab Macrocheira kaempferi

Not only is the giant Japanese spider crab the largest of all crabs, with a leg-span of up to 13 ft (4 m) and weighing 35–44 lb (16–20 kg), it may also be the longest living, surviving for up to 100 years. Living in the deep, cold waters around Japan, this crab moves slowly across the ocean floor on its spiderlike legs, scavenging for food.
