Brown trout ( Salmo trutta fario )

Superclass : Jaw mouths (Gnathostomata)
Class : Ray fins (Actinopterygii)
Subclass : Neuflosser (Neopterygii)
Subclass : Real bony fish (Teleostei)
Overcohort : Clupeocephala
Cohort : Euteleosteomorpha
Scientific name
Greenwood , Rosen , Weitzman & Myers , 1966

The cohort Euteleosteomorpha ( Euteleostei as "subdivision" in Nelson (2006)) is a taxon of the Teleostei (bony fish in the sense ), namely the derived sister group of the Ostarioclupeomorpha (Otomorpha). It comprises the four sub-cohorts Lepidogalaxii ( monotypic ), Protacanthopterygii , Stomiati and Neoteleostei , but is not very comprehensively defined, namely, according to Johnson and Patterson (1996) only by three skeletal synapomorphies :

  1. The first supranural (predorsal) arises independently of the second, is wider than this and separated from it by two (or more) neural spines. The supraneuralia between the occiput and the dorsalis first increase in length, then decrease, quite symmetrically.
  2. The stegural is membranous in front (lamina; secondary to the Argentinoidei . Stegurale is the name given to uroneuralia , which are fused with the last pre-neural vertebral center to stiffen the tail).
  3. Cartilage is present at the base of the radii of the caudalis (caudal fin) (but it is absent secondarily in pike-like and acanthomorpha (spiny fins in the main)).

According to Joseph S. Nelson , the Euteleosteomorpha belong to 28 orders, 346 families, 2935 genera and 17,419 fish species.

The following cladogram shows the systematic position of the Euteleosteomorpha:


 Clupeomorpha ( Herring-like )




 Ostariophysi ( Carps , Characiformes , catfish , etc.)


 Lepidogalaxii ( Lepidogalaxias salamandroides )


 Stomiati ( smelt-like , Maulstachler )


 Neoteleostei ( deep-sea tadpoles , lizardfish relatives , lantern fish-like , Acanthomorpha )


 Protacanthopterygii ( galaxies , golden salmon- like , salmon- like , pike-like )
