Other common names include black rockfish, bonaeci arara, and marbled rockfish.〔Ferreira, B. P., et al. 2008. (''Mycteroperca bonaci''. ) In: IUCN 2012. IUCN Red List of Threatened Species. Version 2012.2.

==Description==
The black grouper is a large marine fish, growing up to 150 cm in length and 100 kg in weight. It has an olive or gray body, with black blotches and brassy spots. The preoperculum is gently rounded.
The black grouper is a solitary fish. The fish spawns between May and August. It is a protogynous hermaphrodite, i.e. the young are predominantly female, but transform into males as they grow larger.
Adults feed mainly on other fish and squid, though the younger fish feed on crustaceans, especially shrimp.
