Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 9 - 12; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 12 - 15; Ryggkotor: 62 - 69. Caudal fin broadly and finely forked; pectorals small, truncate, first ray notably flattened (Ref. 6885). Dark green to blue on dorsal surface, silvery below, small bright blue blotches distributed haphazardly on sides; fins on lower part of body pale, others with darkened rays (Ref. 6885). Branchiostegal rays: 12-15 (Ref. 36573).
Body shape (shape guide): elongated.
Adults are generally found offshore, usually near surface, in schools (Ref. 2850). Juveniles associate with drifting seaweed (Ref. 12114, 12115). Feed on small crustaceans, and eggs and larvae of fishes. May glide above the surface of the water when moving away from predators. Prey of Thunnus alalunga and other scombrids (Ref. 9339). Oviparous, with larvae neustonic (Ref. 36573). Eggs are attached to one another and to floating objects via filaments on the shell surface (Ref. 36573). Utilized dried or salted, canned and frozen; also used for fishmeal and pet food; can be pan-fried and broiled (Ref. 9988).
