Unlike many other sea Sparidae (sea bream, bream ...), it lives near the surface. It is sometimes found in ports where it feeds on waste. In some countries, it is highly prized by fishermen although its flesh is rather soft.

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.

It lives at shallow depth. It is voracious and does not hesitate to strip fishermen’s hooks. Reproduction takes place from March to May. The male delimits a territory with a natural crevice. Several females deposit sticky eggs. The male will watch the eggs until they hatch.

The palette surgeonfish sports a pair of venomous, erectable scalpel spines at the base of its tail, used for self-defense against predators. It primarily dwells in small groups within coastal reefs. Its electric blue color inspired the character of Dory in "Finding Nemo" and "Finding Dory".

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.

Industrial fishing has endangered spawning stocks of the species. Its flesh is sometimes used to make "coley" sticks (Fish sticks). It has been attempted to use the fish for pisciculture. But because of the low profitability, farming the fish was abandoned.

This predator lives in rocky areas, generally at depths of up to 600 meters. Endangered, this species is vulnerable to overfishing due to its slow growth and late maturation, with declining populations observed in areas such as Brazil, Bermuda, and the Azores. Conservation efforts are crucial to protect this species, particularly through fisheries regulation and the protection of essential marine habitats for their survival.

It is accommodated to life in freshwater. It is ovoviviparous: the eggs hatch in it body, and it gives birth to fully formed juveniles. It acclimate easily in aquariums, but beware of the stings from its tail that can inflict very painful wounds.

This fish lives near diadem-urchins. At the slightest danger, it takes refuge between the long spines of sea urchins. The male guards the eggs in the mouth until they hatch. It is threatened in the wild because of fishing for the aquarium trade. This species breeds in captivity.

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.

During the day, it lives in schools and often "grazes" Posidonia leaves (underwater flowering plant). It also eats small animals that live hanging on the leaves. Juveniles live in very shallow waters. It flesh, soft and bland, is not appreciated.
