Western Tropical Pacific Ocean - List of fishes

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.

This dartfish is easily recognizable by its two-tone blue and black body. Like its counterparts, adults live in pairs in burrows they dig in the substrate.

The dark-banded fusilier is recognizable by its vibrant colors, with a pale pink to red underside and a green-blue upper part. This diurnal fish forms large schools in the coral reefs of the Indo-Pacific Ocean. Its primary diet consists mainly of plankton.

The large pectoral fins of this fish serve as a fish net to capture prey. Its color (alternating dark and light bands) indicate to predators that it is poisonous: there are poison glands in the skin covering its spines. It can cause serious or fatal accidents.

The whale shark, the largest living shark in the world, frequents tropical and subtropical waters, excluding the Mediterranean Sea. Despite its massive size, it is harmless to humans. Its population has declined due to fishing, and its conservation remains a challenge. These sharks move slowly and feed on plankton, small fish, crustaceans, and squid. They undertake seasonal migrations, and some populations are relatively isolated. Concerns have been raised about the impacts of tourism on their behavior.

This moray is narrower than most other species. Over time, the male becomes a female (protandrous hermaphroditism). This sex change is accompanied by a color change. This moray adapts easily to life in the aquarium.

This squirrelfish is recognizable by its fine horizontal white stripes with silvery highlights on a predominantly red body. Like its counterparts, it is a nocturnal, exclusively carnivorous fish. It particularly preys on mollusks and small crustaceans living among the rocks.
