Taxonomic Remarks
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).

Könsmognad: Lm 2.8, range 2 - ? cm

Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0; Ryggkotor: 40 - 43. Lower gill raker counts, show some correlation with geographical area, suggesting that the species may comprise three races or subspecies. W-shaped pelvic scute; pre-maxillae toothed, 1 supra-maxilla; isthmus slender, but with slight 'shoulders' anteriorly; vertebrae 40 to 43 (usually 42 - Venezuela); silver lateral band not becoming narrower or fading near gill opening (Ref. 188). Chest is slightly keeled. Small anal fin. Faintly greenish above (Ref. 37032).
Body shape (shape guide): fusiform / normal; Cross section: oval.
A schooling species usually occurring inshore. Feeds on zooplankton. Preyed upon by many larger fishes and squids (Ref. 5521). Important as live bait for scombrids (Ref. 26340). In 1937, at Kingston, Jamaica it spawns during the winter months. Travels long distance (Ref. 37032).
