Description The crevalle jack, Caranx hippos (also known as the common jack, black-tailed trevally, couvalli jack, black cavalli and yellow cavalli) is a common species of large marine fish classified within the jack family, Carangidae. The crevalle jack is distributed across the tropical and temperate waters of the Atlantic Ocean, ranging from Nova Scotia, Canada to Uruguay in the west Atlantic and Portugal to Angola in the east Atlantic, including the Mediterranean Sea. The crevalle jack is distinguishable from similar species by its deep body, fin colouration and a host of more detailed anatomical features including fin ray and lateral line scale counts. It is one of the largest fish in the genus Caranx, growing to a maximum known length of 124 cm and a weight of 32 kg, although is rare at lengths greater than 60 cm. The crevalle jack inhabits both inshore and offshore waters to depths of around 350 m, predominantly over reefs, bays, lagoons and occasionally estuaries. Young fish dispersed north by currents in the eastern Atlantic are known to migrate back to more tropical waters before the onset of winter; however if the fish fail to migrate, mass mortalities occur as the temperature falls below the species tolerance limits.


Habitat Estuaries, tidal flats & salt marshes, Ocean or bay shallows, Open ocean, Rivers & streams, Tidepools.


Range New England, Mid-Atlantic, Southeast, Florida, Texas, California, Eastern Canada.
