The Spratelloididae are a family of herring-like (Clupeiformes) occurring in the tropical western Atlantic (genus Jenkinsia ) and in the tropical Indo-Pacific (genus Spratelloides ).

features

The Spratelloididae are elongated, silvery schooling fish that can reach body lengths of 4 to 12 cm. Diagnostic features of the group include a. a single epurale, an elongated, free-standing bone in the caudal fin skeleton and the fusion of two vertebral centers in the caudal spine ("fusion of the first ural centrum with the first preural centrum"). In addition, 19 molecular biological characteristics were determined.

Systematics

The group was for some time led as a subfamily of the round herring ( Dussumieriidae), which are the sister group of the wolf herring (Chirocentridae). The Spratelloididae, on the other hand, are in a sister group relationship to a hitherto undescribed pedomorphic taxon that occurs in the Philippines. In October 2018, they were therefore raised to family rank.
