Atheriniformes, also known as the silversides, is an order of ray-finned fish that includes the Old World silversides and several less-familiar families, including the unusual Phallostethidae.
[edit] Description
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.[1] Atheriniform larvae share several characteristics; the gut is unusually short, there is a single row of melanophores along the back, and the fin rays do not become evident until some time after hatching.[1]
[edit] Taxonomy
Classification of the atheriniforms is uncertain, with the best evidence for monophyly in the larval characteristics mentioned below.[1]
Nelson, 2006, the family Melanotaeniidae includes the subfamilies Bedotiinae, Melanotaeniinae, Pseudomugilinae, and Telmatherininae, to demonstrate their monophyly.[1] However, in a 2004 study, a different classification scheme classifies the families Bedotiidae, Melanotaeniidae, and Pseudomugilidae (also include Telmatherinine genera) in a suborder Melanotaenioidei.[2] Thus, the number of families in Atheriniformes varies from author to author.
