Lybia is a genus of small crabs in the family Xanthidae. Their common names include boxer crabs boxing crabs and pom-pom crabs. They are notable for their mutualism with sea anemones which they hold in their claws for defense. In return the anemones get carried around which may enable them to capture more food particles with their tentacles. Boxer crabs use at least three different species of anemones including Bundeopsis spp. and Triactis producta.
