Japanese Spider Crab

The Japanese spider crab (Macrocheira kaempferi) is the largest living arthropod and has ten very long legs. The eldest specimens, which can be up to a century old, can measure up to 4 m across! Although ours is very large, it was not as old as this.
Like many other crab species, it mainly feeds on dead animals, although it has been known to kill and eat other crustaceans.
