The coconut crab is the only species of the genus Birgus, and is related to the terrestrial hermit crabs of the genus Coenobita.It shows a number of adaptations to life on land.he coconut crab can take a coconut from the ground and cut it to a husk nut, take it with its claw, climb up a tree 10 m (33 ft) high and drop the husk nut, to access the coconut meat inside. They often descend from the trees by falling, and can survive a fall of at least 4.5 metres (15 ft) unhurt.
Birgus. The coconut crab (Birgus latro) is a type of land hermit crab with a spectacular appearance and intriguing biology. Able to grow to relatively gigantic proportions, the coconut crab is probably the largest terrestrial arthropod in the world. The coconut crabâs claws are powerful enough to crack open coconuts, and can be used to lift weights of up to 28 kg. 2  If coconuts are not readily available on the ground, the coconut crab can climb trees and cut them down.
