Key to the Cypriniformes

Cypriniform fishes can be diagnosed on the basis of:

  • Specialized pharyngeal teeth
  • Most with protractile upper jaws
  • Adipose fin usually absent
  • Opercular canal usually present (secondarily lost in phoxinins and some other cyprinids)
  • Jaws and palate toothless
  • Pharyngeal teeth oppose basioccipital, rather than dorsal pharyngeal elements; area of basioccipital involved with pharyngeal teeth covered by pad
