The horseshoe crab is a living fossil. It has been on Earth some 220 million years, longer than dinosaurs. And it survives today almost identical to its ancient ancestors. Horseshoe crabs get their name because their arc shaped carapace, or exoskeleton, has been compared to the shape of a horse's shoe. Their body is divided into three sections, the first of which contains their mouth, a pair of feeding pincers and five pairs of legs.
