Napoleon fish (Cheilinus Undulatus)
Characterized by an historical name and a highly distinctive look, the Napoleon fish is one of the largest coral reef fishes (the maximum reported length and weight are 230 cm and 190 kg, respectively).
Its body is deep and sturdy, laterally compressed, the distinguishing feature of its head is a prominent globular hump located on the forehead, that is uneven and develops as the fish ages.
Although you hardly see them, some big molars are situated in the back of its protractile mouth, that is surrounded by thick fleshy lips. These molars enable the fish to break even big shells, to feed on their molluscs. Fish, crustacean, echinoderms and other invertebrates too are part of its nourishment; it is one of the few predators eating poisonous preys, such as sea hares, boxfish and crown-of-thorns sea stars (Acanthaster Planci, which devours considerable coral reef stretches every year).
The Napoleon fish lives at a depth ranging from 2 and 60 metres. It swims using its pectoral fins as if they were bird wings, this makes the fish manoeuvrable. It is by nature solitary, sedentary and only active during daylight. At nightfall it goes to sleep among the corals.
At Nika Island Resort & Spa you may encounter it in three dive sites, that can easily be reached: Kuda Thila, Blue Caves and Gangehi Kandu.
The Napoleon fish is listed as endangered, since its flesh and lips are sought-after dishes.
If you are lucky enough to come up against this fish, you will notice how slow it moves. There’s nothing to be afraid of: it is friendly and it easily approaches humans.
A recommendation: do not ever feed fish – you would seriously harm their liver. Note that bread dilates their stomach and this could also lead to death.
