- List of fishes

It is found between 30 and 200 meters deep. It lives near cavities where it takes refuge in case of danger. The male has large pectoral fins and is surrounded by a harem of a dozen females. If it dies, the dominant female becomes a male (protogynous hermaphroditism).

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.

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 one of the most colorful Mediterranean fish. The female has a black spot on the dorsal fin. The stain will disappear and its color becomes more vivid when it will change sex (hermaphroditism protogynous). It is more abundant in the northern Mediterranean.
