"A fully grown Japanese spider crab can reach a leg span of almost 13 feet, a body size of up to 15 inches and a weight of up to 44 pounds. The crab's natural habitat is on the bottom of the Pacific Ocean around Japan, where it feeds on dead animals and shellfish. It is believed to have a life expectancy of up to 100 years. Because it is a particularly old species of crab, it is often referred to as a living fossil. The crab has an orange body and white spots on its legs. Its compound eyes are situated on the front, and two thorns stick out between them. The Japanese spider crab is also used for research and ornamental purposes. In spite of its ferocious appearance, it has a gentle disposition." (from www.aquarium.org) Taken at the Oregon Coast Aquarium in Newport, Oregon. No color manipulation by me; the blueness is due to the lighting in the tank.
