Unlike other bream species living in the Mediterranean, it has elongated jaws. It is often found in groups formed by other species of fish (bream, salemas). It is highly sought after by fishermen because its flesh has a very fine taste.

They often live in small groups. It teeth allows it to crush the shells and shells of its prey (sea urchins, crustaceans, bivalves ...). It is prized for its meat, with a very fine taste.

The dusky grouper is a major predator of shallow rocky areas, hunting stealthily for octopuses, invertebrates, and fish. Despite its global distribution, it is threatened by overfishing. This species has been protected on the French Mediterranean coast since 1993. The combined effects of regulations, climate change, and marine protected areas contribute to the successful restoration of grouper populations, which are increasing once again.

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 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.

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.

It is especially active at dusk. During the day, it stays on the bottom. It can close it eyes with a sort of eyelids. Its flesh is edible, but it liver is toxic! Its eggs can be incubated and hatched in an aquarium.

The African penguin, native to the coastal areas of South Africa and Namibia, is recognizable by its black and white plumage. This penguin primarily feeds on fish and squid. Like its relatives, the African penguin breathes air outside of the water and is capable of long dives underwater. Its aquatic outings frequently reach depths of 15 meters, but some individuals have been observed at over 70 meters. During the breeding season, males sing to attract females. Females also vocalize to strengthen the couple's bond.

The black seabream is a prized species in western fisheries. It lives alone or in large groups near seagrass beds and rocky bottoms, seeking small invertebrates such as crustaceans or mollusks.
