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.
Wo und wann man eines sieht
„Resident" bedeutet, dass die meisten Tauchgänge am jeweiligen Tauchziel eine Begegnung erwarten lassen; „saisonal" bedeutet, dass die Art in den genannten Monaten zuverlässig anzutreffen ist; alles andere ist ein Bonus, keine Planungsgrundlage.

Sie verstehen
Lebensraum: Outer reef slopes, channels, and lagoon passes; sleeps in caves and returns to favored ranges for decades
Verbreitung: Indo-Pacific coral reefs from the Red Sea and East Africa through Southeast Asia and Micronesia to the central Pacific
Verhalten: 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.
Ernährung: Mollusks, crustaceans, urchins, and toxic prey few others touch — crown-of-thorns starfish and boxfish included
Größe: typischerweise rund 1.2 m; dokumentiert bis zu 2.0 m (total length; the largest wrasse, with old males approaching 200 kg).
Wie man sich in ihrer Nähe verhält
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.
Naturschutz
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.
