Diagnosis

Diagnosis_Genus: Seriola Cuvier. Different from the Caranx, because the end of their lateral line is furnished with scales so small that they hardly form a keel. There is one species in the Mediterranean. Caranx dumerili (Risso): Large silvery fish, with purplish back, with bluish fins which approach our coasts only rarely and in isolation.

Diagnosis_Species: Caranx Dumerili Risso 1810. C. Linea laterali laevissima; pinnis luteo, griseo, caeruleoque variis. This species, still unknown to the authors, differs from previous species, not only by the beautiful colors of its scales, and by its enormous size; but also by her behaviour, since she lives isolated and travels alone on uncrowded places of our shores. His body is compressed with a silver gray, shaded violet on the back, and a matte white with a slight golden tint on his belly. The muzzle is rounded; The mouth wide, the jaws equal, lined with small teeth, eyes gilded. The lateral line is curved. The fins are colored with yellow, blue and gray. The first ridge contains seven goaded rays; The second, thirty-two articulated; The anal, twenty; It is preceded by two prickles; The pectorals, which are yellowish, have eighteen rays each; The thoracins, five each; And the forked caudal fin, eighteen. This Caranx inhabits the inaccessible places of our sea and approaches the shores only when it seems to be attracted by hunger; We then take the weight of eight myriagrams; Its flesh is reddish, firm and of exquisite taste.

Ecology

Habitat: Coastal
Habitat: A subtropical species, the greater amberjack is often associated with rocky reefs, floating debris, and wrecks at depths ranging from 60-240 feet. It has also been reported at inshore locations off the coast of Florida. Studies have shown that some greater amberjack populations are full time residents along the gulf and Atlantic coasts of Florida while other populations migrate from the South Atlantic Bight into inshore waters during certain times of the year. Greater amberjack congregate in schools when they are young, however this schooling behavior decreases as the fish grows older. The oldest fish are primarily solitary.
