Napoleon wrasse are among the largest bony fish on Indo-Pacific reefs, reaching two metres and 190 kg. Their thick fleshy lips and steep forehead hump make them unmistakable; they feed on hard-shelled prey including sea urchins and crown-of-thorns starfish, providing a regulatory service on reef ecosystems. The species is Endangered globally due to targeted fishing for the live reef food fish trade.
