Big Fish
Napoleon (Humphead) Wrasse
Cheilinus undulatus · Bony fish, family Labridae
Every great Indo-Pacific reef has its Napoleon, and divers learn them by name. The fish is unmistakable: a wardrobe-sized wrasse in chalkboard green scribbled with maze lines, thick lips set in permanent diplomacy, the adult's forehead hump rising like a bicorne hat. It ambles rather than swims, pausing to crunch an urchin or turn a heavy eye on the dive group. Old individuals at Blue Corner or Shark Reef treat humans as familiar furniture. The species pays for that trusting bulk: prized as a luxury live-reef food fish, it has been stripped from much of Southeast Asia, and the big tame residents of protected reefs are now among its safest populations.
Onde e quando ver um
"Residente" significa que a maioria dos mergulhos naquele destino os encontra; "sazonal" significa presença confiável nos meses listados; qualquer outra coisa é um bônus, não um plano.

Melhor mês, em resumo
Entendendo-os
Habitat: Outer reef slopes, channels, and lagoon passes; sleeps in caves and returns to favored ranges for decades
Distribuição: Indo-Pacific coral reefs from the Red Sea and East Africa through Southeast Asia and Micronesia to the central Pacific
Comportamento: A slow-cruising reef monarch, usually solitary, patrolling with pectoral-fin rowing strokes and an air of proprietorship. Naturally wary where fished; at protected sites like Ras Mohammed and Palau's channels, individuals become famously tame, inspecting divers eye to eye. Born mostly female, with dominant animals changing sex to male.
Dieta: Mollusks, crustaceans, urchins, and toxic prey few others touch, crown-of-thorns starfish and boxfish included
Tamanho: normalmente cerca de 1.2 m; documentado até 2.0 m (total length; the largest wrasse, with old males approaching 200 kg).
Como se comportar perto de um
No feeding (it distorted behavior badly at several famous sites), no touching, and let a curious fish make the approach. Report obviously missing 'resident' Napoleons to operators; they are individually known.
Conservação
Endangered and CITES-listed; the live reef-fish trade drove collapses across Southeast Asia, and enforcement plus site protection now underpin the strongholds divers visit.
