Lutjanus cyanopterus, commonly known as the cubera snapper, is a large marine fish found in the western Atlantic Ocean. It inhabits coral reefs and rocky bottoms, often at depths of up to 55 meters. This species is notable for its robust body, powerful jaws, and reddish-brown coloration with pale underside. Adult cubera snappers can reach impressive lengths of up to 160 cm (63 inches) and are known for their solitary and territorial behavior.

Lutjanus cyanopterus, commonly known as the Cubera Snapper, is native to the Western Atlantic Ocean. Its geographical distribution ranges from the eastern coast of the United States, particularly North Carolina, down through the Gulf of Mexico, the Caribbean Sea, and along the eastern coast of Central and South America to Brazil.

Cubera Snappers typically inhabit coral reefs, rocky areas, and mangroves. They prefer depths ranging from 25 to 50 meters but can be found in waters as shallow as 10 meters or as deep as 100 meters. The species thrives in warm tropical and subtropical waters with temperatures generally between 22°C and 28°C.

As a top predator in its habitat, the Cubera Snapper plays a crucial role in maintaining the balance of reef ecosystems. It feeds on a variety of prey, including fish, crustaceans, and cephalopods, which helps control the population of these organisms. The species is also known for its ability to adapt to different reef structures and depths, allowing it to occupy various ecological niches within its range.
