Issue
The species in the genera Spratelloides Bleeker, 1851 and Jenkinsia Jordan & Evermann, 1896 should most probably be assigned to a separated family from Clupeidae and Dussumieriidae (Lavoué, pers. comm., July 2013). See a preliminary analysis in Lavoué et al. (2013: Ref. 93878).

Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 11 - 13; Espinas anales: 0; Radios blandos anales: 10 - 11. No bright silver along band flanks, maxilla toothless; pre-maxillae triangular, 2 supra-maxillae, second supra-maxilla paddle-shaped and symmetrical; vertical striate on scales meeting at center, posterior margin of scales smooth, pre-dorsal scales 8 to 13; W-shaped pelvic scute, few branchiostegal rays (6 or 7).

Pelagic (Ref. 68964). Usually an inshore schooling species, inhabiting relatively clear coastal waters, lagoons, and along reef margins. Feeds near surface on plankton. Found in large schools (Ref. 9710). Pelagic (Ref. 58302). Marketed fresh or dried-salted (Ref. 5213) and used as tuna baitfish.
