Ostarioclupeomorpha
Arratia , 1997

The Ostarioclupeomorpha , Otomorpha or Otocephala , are a cohort of the Teleostei (bony fish i. E. S. ) and the derived sister group of the Euteleosteomorpha . They include the three cohorts Clupei ( clupeiformes ) Alepocephali and Ostariophysi ( Cypriniformes , Characiformes , catfish , et al..), But are not very broadly defined, namely after Arratia (1997) only by three skeletal synapomorphies :

1. The middle extrascapular (a skull bone) is fused with the parietal bone or with the parietal bone and supraoccipital (skull bone) or connected in a rigid joint.
2. The autopalatine, a pair of bones in the palate of the fish, ossifies early in the course of ontogenesis .
3. The bases of the first and second hypuralia are not cartilaginously connected at any stage of growth.

Other possible synapomorphies are:

1. The front section of the swim bladder is covered with a silvery coating.
2. The hemal arches are fused with the vertebral centers from an early stage of youth.

Systematics

According to Joseph S. Nelson , the Ostarioclupeomorpha belong to 6 recent orders, 73 families, 1159 genera and 8295 fish species.

The following cladogram shows the systematic position of the Ostarioclupeomorpha:
