''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''. The bonding with the anemone is not required for survival, however, and boxer crabs have frequently been known to live without them, sometimes substituting other organisms such as sponges and corals for the sea anemones. The genus ''Lybia'' contains the following species: *''Lybia australiensis'' (Ward, 1933) *''Lybia caestifera'' (Alcock, 1898) *''Lybia denticulata'' Nobili, 1905 *''Lybia edmondsoni'' Takeda & Miyake, 1970 *''Lybia hatagumoana'' Sakai, 1961 *''Lybia leptochelis'' (Zehntner, 1894) *''Lybia plumosa'' Barnard, 1947 *''Lybia pugil'' (Alcock, 1898) *''Lybia tessellata'' (Latreille ''in'' Milbert, 1812) *''Lybia tutelina'' C.
