The yellowmouth grouper inhabits rocky reefs and drop-offs across the western Atlantic, typically at depths between 20 and 100 metres. A robust, stocky grouper, it is identifiable by its dusky body and the distinctive yellow-orange colouration inside its mouth — visible when the fish yawns or feeds. Like other groupers, it is a solitary ambush predator, lying in wait among rocks and coral crevices before striking at passing prey with explosive speed.
