Scales numerous, small, usually lost (Ref. 37816).Colouration: Silvery; back bright blue, fading to grey; flanks bright silver (Ref. 37816).

Occurs in inshore waters of the continental shelf (Ref. 75154).

Pelagic in coastal waters, from the shore to a depth of about 150 m (Ref. 30573). It feeds on small fish and crustaceans (Ref. 5213, 30573). Marketed fresh or frozen.

分布於印度-太平洋暖水海域，西起紅海、非洲東部，東至所羅門群島，北至臺灣，南至澳洲北部。臺灣四周海域及澎湖均有產。

一般利用流刺網或一支釣等漁法捕獲。但因為魚體瘦薄，肉質較少，因此並非主要經濟魚種，市場上亦較少見。
