Napoleon Wrasse (Ikan Napoleon)
Cheilinus undulatus
Napoleon wrasse are impossible to miss — massive reef fish that can reach two meters, with pronounced lips and a distinctive forehead hump in adults. They move slowly and deliberately through reef channels, often approaching divers out of curiosity.
Where you might see it
Most reliably spotted along outer reef slopes and drop-offs where coral cover is dense. They patrol reef edges in deeper water, typically 15-30 meters, though occasionally venture into shallower channels.
How to spot it
Watch for a large, slow-moving silhouette patrolling the reef edge. The thick lips, bulbous forehead, and blue-green coloring with darker vertical markings make adults unmistakable. They often investigate divers, swimming close with calm curiosity.
Responsible Encounter Guidelines
- •Let it approach on its own terms — don't chase or crowd for photos.
- •Never feed them, even if they seem curious or accustomed to divers.
- •Move slowly and avoid sudden descents that might spook them.
- •Stay stable in the water — don't sink onto coral or seagrass
