Natural History

Crevalle jacks are similar to other jacks, with deep elongated bodies and triangular pectoral, dorsal, and anal fins. They have a unique golden colour and a black tail, which are characteristic of this species.


These fish are powerful predators at every stage of life. Even as juveniles they attack and eat other fish. They do, however, hold a widely variable diet; their food sources will change by season and year.

Least Concern

Conservation Status

Despite local declines due to human exploitation, the global population size remains steady. Without major threats to its population, it is assessed to be of “Least Concern” by the International Union for Conservation of Nature (IUCN).

Interesting Facts

  • Young crevalle jacks, pushed north by currents tend to migrate to tropical waters before winter sets. If they don’t, mass mortalities will occur if it gets too cold for them.
  • The largest fish of this species was reported to be 124 cm (48.8 in) long at 32 kg (70.5 lbs).
