SHORT
DESCRIPTION
Elongated body, posterior end of upper jaw relatively broad. In adults, length of dorsal fin lobe equal or slightly longer than pectoral fin, and usually 15-18% of fork length. Soft anal fin base usually 58-66% of second dorsal fin base. Anterior margin of first pterygiophore of anal fin moderately concave. Caudal peduncle grooves present. Lateral line without scutes.
color :
adults dark pink dorsally and laterally, darker on the head, and pale ventrally. Juveniles, smaller than 20 cm fork length, yellow with 5 dark body bars, irregular and broken, that do not extend onto membranes of soft dorsal and anal fins, and an sixth bar, small and dark, at end of caudal peduncle.
size :
in the Mediterranean, on average, 65 cm fork length. In the Atlantic to 55 cm fork length.

DISTINGUISHING CHARACTERISTICS
Seriola dumerili: the number of gill rakers decreases with growth from 18-24 in small individuals to 11-19 in fish larger than 20 cm fork length.
Seriola fasciata: end of upper jaw relatively slender and eye relatively big.
Seriola rivoliana: length of second dorsal fin lobe longer, usually 19-22% of fork length.
BIOLOGY / ECOLOGY
Its biology is little known; diet composed by squids and fishes, and its spawning probably occurs in August-September. The species is shorter at sexual maturity than Seriola dumerili, which the first spawning occurs at 91 cm total length (Marino et al., 1995).
habitat :
juveniles epipelagic in oceanic or offshore neritic waters and adults benthopelagic, generally restricted to coastal waters over the continental shelf, from the surface to at least 200 m depth.
