The Japanese spider crab, (Macrocheira kaempferi), is a very leggy deep-sea arthropod, and it’s the largest known arthropod. The Japanese spider crab shown—nicknamed Crabzilla—measures “10ft from claw to claw – is still growing, and could live until it is 100.” According to the Daily Mail, Crabzilla will be “display[ed] at the National Sea Life Centre in Birmingham.”
