Birgus latro
loves eating coconuts, and the juveniles also use the shells for protection.
It is a very skillful climber and can scale coconut trees 18 meters high.
There it uses its heavy, sharp claws to tear off the coconut husk and puncture a hole in the coconut shell.
The coconut meat is extracted with the smaller pincers. This crab, which is considered
the largest land-living arthropod, has gills modified to function as lungs.
It spawns in the ocean where the young pass through the larval stage. After maturing they
leave the ocean permanently and lose the ability to breathe in water.
