SHORT DESCRIPTION Body elongate and moderately deep. Two dorsal fins, the first much smaller than the second. The first dorsal and anal rays distinctively longer than all others (19-22% of fork length). Caudal fin deeply forked. Upper jaw broad with wide supramaxilla, extending back to center of eye. First gill arch with 22-24 gill rakers in adult specimens. color : adults with silvery violet to olive or blueish-green back which gradually changes to silvery on the ventral surface. Often with yellow elongated areas on the sides. Young (up to 20 cm Total Length) have a dark bar from the eye to dorsal fin origin and 6-7 bars on the body. size : 50-80 cm (max. 120 cm). DISTINGUISHING CHARACTERISTICS Seriola spp.: length of second dorsal fin lobe 11-18% of fork length. BIOLOGY / ECOLOGY Feeds on pelagic fishes and invertebrates. Eggs and larvae planktonic. habitat : pelagic, probably more oceanic than its congenerics. Juveniles found offshore under floating objects.

1st MEDITERRANEAN RECORD 2000, Lampedusa Island. DISTRIBUTION Worldwide: in all tropical seas and warm temperate regions. Mediterranean: recorded off Lampedusa Island (Central Mediterranean) (Castriota et al., 2002). ESTABLISHMENT SUCCESS Only a single specimen has been recorded in the Mediterranean. However, due to its similarity to Seriola dumerili, it may have been confused for the latter and may be therefore more common. speculated reasons for success : - MODE OF INTRODUCTION Via Gibraltar. IMPORTANCE TO HUMANS Commercially important in its original distribution regions.
