Classification

Ten species of the single extant genus Polymixia are known,^[1] along with several fossil genera.

At present they are classified in their own order Polymixiiformes,^[2] but as Nelson says, "few groups have been shifted back and forth as frequently as this one".^[3] Previous groupings include Beryciformes. Families (seven, see text) Suborder Berycoidei Berycidae -- alfonsinos, berycids Suborder Holocentroidei Holocentridae -- soldierfishes, squirrelfishes Suborder Stephanoberycoidei Suborder Trachichthyoidei Anomalopidae -- flashlight fishes, laterneye fishes Anoplogastridae -- fangtooth fishes, fangtooths Diretmidae -- spinyfins Monocentridae -- pineconefishes Trachichthyidae -- redfishes, roughies, slime heads External link http://www. ...
