Call him a coconut crab, robber crab, or a palm thief, but don't call him late for dinner. This huge and super strong land crab is related to the hermit crab. While they are not the biggest crabs in the world, they are right there up there with biggest. They are, however, the biggest land-dwelling arthropod.
The coconut crab is super strong. They can easily crack open coconuts for a tasty afternoon snack. Despite being called a coconut crab, however, they actually enjoy eating a variety of other stuff. They will eat fruit, nuts, seeds, rats, and seabirds.
