Among the largest bony fish on coral reefs, male Napoleon wrasse can reach 2 metres and are unmistakable with a steep forehead hump, thick fleshy lips, and vivid blue-green patterning. They feed on hard-shelled invertebrates including sea urchins and crown-of-thorns starfish, playing an important regulatory role on reefs. Endangered globally due to targeted fishing for the live reef food fish trade, the individuals at Manado Tua are habituated to divers and often approach within arm's reach.
