Atheriniformes

The Atheriniformes, also known as the silversides, are an order of ray-finned fishes that includes the Old World silversides and several less-familiar families, including the unusual Phallostethidae. The order includes at least 354 species. They are found worldwide in tropical and temperate marine and freshwater environments.〔
== Description ==
Atheriniformes are generally elongated and silvery in colour, although exceptions do exist. They are typically small fish, with the largest being the jacksmelt, with a head-body length of , and the smallest species, such as the Bangkok minnow, being only in adult length.
Members of the order usually have two dorsal fins, the first with flexible spines, and an anal fin with one spine at the front. The lateral line is typically weak or absent.〔 Atheriniform larvae share several characteristics; the gut is unusually short, a single row of melanophores occurs along the back, and the fin rays do not become evident until some time after hatching.〔 They scatter their eggs widely, with most species attaching them to aquatic plants.〔
