Size: Up to 8 feet and 800 pounds; largest grouper species in western Atlantic waters

Habitat

Coastal and nearshore waters over structure or muddy bottoms. Young often occur in estuaries, especially around oyster bars. More abundant in southern Florida than in northern waters.

Behavior

Spawn during summer months and have a lifespan of 30 to 50 years.

Opportunistic predators and feed mostly on slow-moving, bottom-associated species. Calico crabs make up the majority of their diet, with other invertebrate species and fish filling in the rest. Will occasionally feed on fish that are struggling on a fishing line, but they have not been shown to actively hunt down fast, free swimming fish such as snappers and groupers. Prey is ambushed, caught by a rapid expansion and opening of the mouth that allows prey to be sucked in and swallowed whole.

Additional Information

Prohibited from harvest.

State Record: 680 lb, caught near Fernandina Beach (1961)
