Decorator crabs are a group of crabs known for their ability to camouflage by attaching materials from their environment to their bodies. They belong to the superfamily Majoidea, which includes spider crabs and other related species. This disguise helps them blend in with their surroundings and evade predators like fish and octopuses. Found in shallow coastal waters, coral reefs, and sandy seabeds.
