Christmas Island: Coconut Crabs
While the red crabs are everywhere, the king of the jungle is the robber aka coconut crab. They are massive, around 20 pounds, and the size bigger than a basketball. They look and move like an armored vehicle. They can crack open a coconut or even sever a human limb. They live up to 80 years and completely adapted to living and breathing on land. They can’t even swim. Critically endangered.
