South East Asian Seas - List of fishes

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.

At night, the yellowbanded sweetlips hunt benthic invertebrates in sandbanks and seagrass beds. During the day, they rest in the crevices and recesses of the reefs. This tropical species, which can grow over 70 cm, is targeted by fishermen in many Pacific Ocean islands.

The Emperor Angelfish is found from the Red Sea to the Great Barrier Reef. Juveniles hide under reef overhangs or in holes in outer lagoons, while adults prefer caves in coral-rich areas. These fish feed on sponges and form pairs for reproduction.

The blue shark, also known as the "blue skin shark," is a pelagic predator found in temperate and tropical marine waters, with occasional sightings near the coast. Its wide distribution, however, is threatened by overfishing. Recognizable by its blue back and white belly, this sleek-bodied shark mainly feeds on small fish, mollusks, cephalopods, and sometimes birds.

The peach fairy basslet is found from the Red Sea to the Great Barrier Reef. Juveniles hide under reef overhangs or in holes in outer lagoons, while adults prefer caves in coral-rich areas. These fish feed on sponges and form pairs for reproduction.

Pseudobalistes flavimarginatus, better known as the "yellowmargin triggerfish" due to the coloration of its body, is a fish belonging to the balistidae family. It is found in tropical waters of the Indo-Pacific. It can be encountered on reefs and estuaries, but can also be observed on slopes and in lagoons.
