Boxer crabs hold sea anemones in their claws like pom-poms—but they’re not cheering! The two critters have a symbiotic relationship: boxer crabs use anemones’ stinging cells for defense, while anemones feed on particles from the crabs’ meals. If a foe gets near a boxer crab, the crab will wave its anemone-covered claws and try to shoo it away. Scientists also think that the anemones provide the crab with a form of camouflage. Another wild fact: if a boxer crab loses an anemone on one of its claws, it will tear a piece of anemone from its other claw, inducing asexual reproduction and cloning a new piece for its bare claw.
