The coconut crab is the world’s largest terrestial arthropod in the world and is known for its ability to crack coconuts with its pincers. They can weigh up to 4kg (Some reports claim up to 17kg) and leg span of 1m. It is eaten by the Pacific islanders and is considered a delicacy with a taste similar to lobster and crabmeat. A coconut crab will attack if it is threatened.
