Coenobita clypeatus is a terrestrial hermit crab native to the western Atlantic and Caribbean region. Adults inhabit coastal environments and can be found considerable distances inland, often burrowing under tree roots. The species exhibits complex social behaviors including shell fighting, vacancy chains for resource acquisition, and size-dependent dominance hierarchies. It relies on scavenged gastropod shells for protection and water retention, with shell availability directly limiting population density and individual growth.
