Red Snapper

The red snapper (Lutjanus campechanus) is a reef-associated fish in the family Lutjanidae, found in the Gulf of Mexico and western Atlantic from North Carolina to the Yucatán Peninsula. It is one of the most recognizable snappers due to its rosy-red coloration and bright red eyes. The species inhabits natural and artificial hard-bottom structure, including rocky ledges, wrecks, and oil platforms, and is an important focus of fisheries management in the region. Red snapper can live several decades and grow slowly, making population recovery a long-term process following periods of heavy fishing pressure.

Key identification features for red snapper:

• Color: overall rosy to brick-red body, generally darker on the back and paler pink-white on the belly.
• Eyes: distinctly bright red iris.
• Teeth: sharp, triangular canine teeth visible at the front of the jaw.
• Body shape: deep-bodied and robust with a somewhat sloped forehead profile and pointed snout.
• Fins: long-based dorsal fin, slightly forked caudal fin.
• Size: adults commonly 40-60 cm, with larger individuals exceeding 90 cm. Red snapper can be told apart from similar-looking snappers by the combination of solid red coloration (no bars or spots) and bright red eyes.

Red snapper are found in the Gulf of Mexico and western Atlantic, from North Carolina south to the Yucatán Peninsula, with the Gulf of Mexico hosting the largest populations. Adults inhabit natural rocky and coral-rock hard-bottom, artificial reefs, shipwrecks, and offshore oil and gas platforms, typically at depths of 10-100 meters. Juveniles settle on softer sand or mud bottom with some structure before moving to more complex hard-bottom habitat as they mature. Water temperatures in its range are warm temperate to subtropical, and adults generally avoid very shallow inshore waters, favoring the outer continental shelf.

Red snapper are structure-oriented fish that form loose aggregations around reefs, wrecks, and platforms, though they are less strictly schooling than many smaller snapper species. They feed opportunistically on fish, shrimp, crabs, and other invertebrates, often near the bottom but also higher in the water column. The species spawns during warmer months, with females releasing eggs that develop as they drift with currents before settling on the seafloor as juveniles. Red snapper are relatively long-lived and slow-growing, with individuals capable of reaching several decades in age, a life history trait that makes populations sensitive to sustained fishing pressure. As both predator and prey, they occupy an important position in Gulf of Mexico and southeastern U.S. reef food webs.
