Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; oceanodromous (Ref. 51243); depth range 55 - 525 m (Ref. 5222). Tropical; 43°N - 34°S, 98°W - 35°W
Western Atlantic: Massachusetts, USA to the Gulf of Mexico, Cuba, Trinidad, Rio de Janeiro and Sao Paulo (Ref. 47377), Brazil. Rare in the West Indies (Cuba, Haiti, and Trinidad). Reports from the eastern Pacific are apparently misidentifications of Epinephelus exsul.
