Napoleon Wrasse (Ikan Napoleon)
Cheilinus undulatus
A massive, charismatic reef fish recognized by thick lips and an adult forehead “hump.” It patrols reef slopes and channels and is a highlight on deeper snorkel/dive sites. Slow-growing and heavily targeted in parts of its range.
HabitatOuter reef slopes, channels, lagoons
DietHard-shelled invertebrates, fish, reef fauna
SizeUp to 2 meters
BehaviorUsually solitary; curious; slow, powerful swimmer
Where you might see it
Best chance on healthy coral reefs and drop-offs, especially around more exposed island reefs (including Una Una’s volcanic reef systems).
How to spot it
Look for a very large silhouette with thick lips and a blunt head. Adults often cruise along reef edges; juveniles stay shallower near sheltered reef areas.
Responsible Encounter Guidelines
- •Keep distance; don’t crowd for photos.
- •Never feed wildlife (changes behavior).
- •Avoid rapid descents/noise that startle it.
- •Maintain buoyancy; protect reef habitat.
- •Choose operators that discourage taking “trophy” shots.
