Oceania - List of fishes

This fish lives camouflaged among the gorgonians. it watches its prey from a promontory and swims quickly toward them to catch them before returning to it observation post. During the breeding season, the male performs a courtship display to attract the attention of a female.

The juveniles of this species have very long fins. They often let themselves drift with the currents in all positions, so they look like dead leaves. Adults sometimes gather in huge schools.

By day, these fish form a small group and remain free from branched corals. At night, the group dislocates and specimens go down near the bottom for food. During the incubation period, the eggs are kept in the mouth of the male. The latter fasts until they hatch.

The scalloped hammerhead shark, a semi-oceanic hammerhead, is found in tropical and temperate waters worldwide. This species is easily recognizable by its curved flat head and black tips on the pectoral fins. These sharks feed on fish, cephalopods, and crustaceans, taking advantage of their flat head to make tight turns while hunting. Although potentially dangerous and aggressive towards intruders, attacks on humans are rare. Conversely, despite its wide distribution, this species is threatened with extinction.

The sailfin snapper frequents sandy bottoms in the immediate vicinity of coral reefs. This usually solitary fish preys on other fish, crustaceans, and various mollusk species. It is a tropical fish occasionally targeted by fishermen.
