The body of the sea bass is spindle-shaped and elongated. Its basic colour is pale, dark or reddish brown, depending on where it lives. Specimens that live in hollows or other dark places are more red in colour. Animals that spend more time in sunny locations, however, are a brownish colour.
Sea bass are territorial and don't stray from home. They live at depths of between 5 and 500 metres, in rocky reefs or above silty and sandy ocean beds. Their diet includes small fish and crustaceans.
