Yellowtail Snapper

Physical Characteristics

Features a prominent, solid horizontal yellow stripe running from the snout to the tail fluke. The body is typically olive to bluish on the back with reddish spots, fading to a silvery-white underside. It has a deeply forked, bright yellow caudal fin. The body is more elongated and streamlined compared to most other snapper species.

Habitat & Distribution

Inhabits tropical and subtropical waters of the Western Atlantic, ranging from Massachusetts to southeastern Brazil. It is most commonly found near coral reefs, shipwrecks, and ledges at depths of 10 to 70 meters, though juveniles often frequent seagrass beds and mangroves.

Size & Weight

Typically reaches lengths of 30 to 40 cm (12-16 inches) but can grow up to 86 cm (34 inches). Average weight is around 0.5 to 2.3 kg (1-5 lbs), with a maximum recorded weight of approximately 5 kg (11 lbs).

Similar Looking Species

The Lane Snapper (Lutjanus synagris) is similar but has a black spot on the side and multiple faint yellow stripes rather than one distinct thick stripe. The Mutton Snapper (Lutjanus analis) is larger with a different tail shape and coloration.

Ecological Role

Functions as a mesopredator, feeding primarily on benthic organisms such as small fish, crustaceans, and cephalopods at night. It is an important prey species for larger groupers and sharks. This species is currently categorized as 'Least Concern' by the IUCN, though local populations are monitored for sustainability.
