  • It has the largest leg span of any arthropod, which are animals with no backbone or external skeleton
  • Males are larger than females and have larger legs that hold their claws, though females have wider abdomens to hold their eggs

Did you know?

  • The Japanese spider crab is not only the biggest crab, but its long lifespan may also make it the longest-lived
  • Their ling legs look impressive but are known to be weak and poorly attached at the joints. Studies have found that a large percentage of crabs caught were missing one or more limbs - which regrow when the crab molts
