Although most people don't think about crabs as bone crushing, kitten-eating, mastadons of the tropics, most people have never met this terrestrial hermit crab. About the size of a small dog, the coconut crab - otherwise known as the robber crab or palm thief - is the biggest arthropod in the world, often weighing up to nine pounds. These nightmare crabs look more like an alien from outer space than a species of Earth, and their look isn't the only crazy thing about them.
There are plenty of creepy coconut crab facts. These guys can use their four-foot long legs to scuttle quickly from place to place; burrow into dark holes in the ground; and even climb soaring coconut trees. Sometimes known to take down a small mammal, the coconut crab is a true marvel of nature and one that continues to frighten and titillate anyone nearby. But while some believe they are harmless beach combers, others have suspected them of much greater crimes. Some speculate they may even have a connection to Amelia Earhart. If you love crabs that are scary, look no further than the coconut crab.
