Japanese spider crab — size comparison — facts and sources

The Japanese spider crab lives off Japan on deep shelf bottoms and continental slopes. Its relatively small carapace accompanies extraordinarily long legs. Leg span rather than body width gives it a record among living arthropods.

It moves slowly over sediment and rock, collecting available food. It eats organic material and bottom-dwelling animals, also using carrion. Long legs cover a large area, while claws grasp food and transfer it to the mouth.
