description Halloween Crab Overview
The Halloween crab (*Gecarcinus quadratus*) is a brightly colored, primarily terrestrial crustacean found in coastal forests and mangroves from Mexico to South America. It is easily recognized by its distinct black carapace and vibrant orange or purple legs and claws, which contribute to its common name. This species digs deep burrows in the forest floor, which help it regulate its internal moisture levels and avoid predators. Although it lives on land as an adult, it must return to the ocean to release its larvae into the tidal ecosystems.
