Physical characteristics
Relatively slender body with a long, pointed snout. Coloration ranges from grayish-green to dark brown on the back and sides, often with a reddish or bronzy tint. It lacks the dark lateral spot found on several other snappers. A dark stripe often runs from the snout through the eye, particularly in juveniles. Features two prominent canine teeth in the upper jaw.
Habitat & distribution
Inhabits coastal waters, coral reefs, mangroves, and seagrass beds in the Western Atlantic, from Massachusetts to Brazil, including the Gulf of Mexico and the Caribbean. Juveniles are common in estuaries and mangroves, while adults move to offshore reefs up to 180 meters deep.
Ecological role
An opportunistic predator that feeds primarily at night on fish, crustaceans, and gastropods. They play a vital role in transferring energy from mangrove and seagrass nurseries to offshore reef systems. The species is currently listed as 'Least Concern' by the IUCN despite heavy pressure throughout its range.
