Body elongated and little compressed; teeth small and uniseriate; lower branch of first gill arch with 42 to 45 gill rakers; edge of shoulders girdle (cleithrum) with a small furrow at its upper end but lacking papillae; lateral line completely scaled, the scales becoming large scutes posteriorly; scutes in the area of the median curve 1.1 to 1.6 times the diameter of the eye; nape and back metallic blue or dark gray; flanks and belly pale; dorsal edge of operculum with a black stain (Ref. 55763). Body elongate and slightly compressed. Body dark blue dorsally, silvery-white ventrally. Black spot on upper posterior margin of opercle. Fins dusky (Ref. 37339).

細長的身體與些微扁長形。 身體深藍色背面, 腹面銀白色的。 在鰓蓋的上面後緣上的黑色的斑點。 鰭暗色的.(參考文獻 37339) 胸鰭鐮刀狀與非常長的.(參考文獻 27363)
Adults are found in the shore and open oceanic waters, in schools. They feed mainly on fish larvae and small crustaceans. Marketed fresh (Ref. 9283). Utilized canned for human consumption and also made into fishmeal (Ref. 9988). The species is often found in Juan Fernández Is. as an incidental catch of Pseudocaranx chilensis (Guichenot, 1848) fisheries (Ref. 89357).
發現於海岸與開放的大洋性水域了。 形成魚群。 主要吃仔魚與小型甲殼動物。 在市場上銷售生鮮地了。 (參考文獻 9283) 利用了罐裝供人類消費以及製成了魚粉。 (參考文獻 9988)
