Fun facts

  • reproducciónIt spends most of its adult life on land, away from the sea, though it has to return to salt water periodically to release its eggs.
  • It grows very slowly: it needs more than sixty moults to reach full size, some three times as many as other crabs, and that is why it lives longer than most land crabs.
  • Six to ten days before moulting it seals the burrow entrance with mud to protect itself while it is soft.
  • The bottom of the burrow holds a pool of water, and the air inside has very high concentrations of carbon dioxide.
  • It feeds mainly on mangrove leaves and fruit, but also on carrion, and is said to turn cannibal.
  • It is an important food in the Caribbean and is overexploited: Puerto Rico has brought in strict rules and Florida has considered doing the same.
