It grows to 90-150 centimetres (35-59 inches) in length. 

It is found in the Mediterranean Sea and the coast of north Africa. It prefers rocky reefs and areas with seagrass. 

It feeds on molluscs (snails), crustaceans (crabs and shrimp), fish, and octopus. 

The Dusky Grouper is solitary and territorial, chasing other fish away from its territory. 

It is a protogynous hermaphrodite, meaning that all fish begin life as a female. As they age, they develop into males. 

The female lays eggs and the male defends the eggs until they hatch.
