Acropomatiformes
The Acropomatiformes or Pempheriformes are an order of fish from the group of perch relatives Percomorpha. The relationship of the families assigned to the Acropomatiformes is based on molecular biological studies and is not yet supported by morphological characteristics. The giant sea bass (''Stereolepis gigas'') of the Eastern Pacific Ocean, with a maximum length of and weight of , is the largest species of the Pempheriformes. As early as 2007, Smith and Craig established a relationship between the wreckfish Polyprionidae, the longfin pike Dinolestes lewini, the armored heads Pentacerotidae and the lanternbellies Acropomatidae. In February 2009, Blaise Li and colleagues described a monophyletic clade composed of the Howellidae, the Lateolabracidae and the deep-sea cardinalfishes Epigonidae in their analysis of the relationships between the various groups of the Acanthomorpha. In a revision of the bony fish systematics published in early 2013 by Ricardo Betancur-R. and c ...
