Notable features include a prominent black spot on the operculum (gill cover), a black spot at the base of the pectoral fin, and a forked tail. The lateral line is strongly arched anteriorly and has prominent boney scutes near the tail.

Habitat & Distribution

Inhabits subtropical and tropical waters of the Atlantic Ocean. Found in both coastal and offshore environments, including bays, estuaries, lagoons, and reefs. They are euryhaline, meaning they can tolerate various salinity levels and are often found in brackish water.

Size & Weight

Commonly ranges from 12 to 30 inches (30–75 cm) and 5 to 15 lbs. They can reach a maximum length of about 48 inches (124 cm) and a maximum weight of 70 lbs (32 kg).

Horse-eye Jack (Caranx latus), which has larger eyes and no dark spot on the operculum; Pacific Crevalle Jack (Caranx caninus), which is found in the Pacific Ocean and has more gill rakers.

Ecological Role

A highly active, diurnal apex predator. They feed primarily on smaller fish, shrimp, and other invertebrates. They often hunt in schools to corner prey. Currently listed as Least Concern by the IUCN, though they are important components of their marine ecosystems.
