The coconut crab (Birgus latro) is one of its most famous species.
Except as larvae, coconut crabs cannot swim, and they will drown if left in water for more than an hour.
The coconut crab has a well developed sense of smell, which it uses to locate its food.
At the time of hatching, the female coconut crab releases the eggs into the ocean.
The coconut crab reaches sexual maturity around five years after hatching.
Once the pores are visible, the coconut crab will bang its pincers on one of them until they break.
Should a coconut crab pinch a person, it will cause pain and be unlikely to release its grip.
There is a bag limit of 5 coconut crabs on any given day, and 15 across the whole season.
Historically, the island has been cited as the home for a large population of edible coconut crabs.
There may be as many as one million coconut crabs on Christmas Island.
