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).

Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 0; Taggstrålar i analfenan 0. No teeth on pre-maxillae, 1 supra-maxilla; W-shaped pelvic scute; isthmus with distinct blunt `shoulders' anteriorly; vertebrae 38 (one fish); silver lateral band not fading away anteriorly. Lower gill raker counts correlated with geographical area: 24 to 28 for J. majua majua (Gulf of Mexico) and 21 to 24 for J. majua woodsi (Bahamas, northwestern Caribbean) (Whitehead, 1963).

Usually an inshore schooling species, feeding on zooplankton.
