Osteichthyes

Examples of Osteichthyes in the following topics:

• Gnathostomes: Jawed Fishes

  • Gnathostomes, jawed vertebrates, can be divided into two types of fish: Chondrichthyes (cartilaginous fish) or Osteichthyes (bony fish).
  • Most modern gnathostomes belong to the clades Chondrichthyes and Osteichthyes.
  • Members of the clade Osteichthyes, also called bony fish, are characterized by a bony skeleton.
  • A few groups of Osteichthyes, such as sturgeons and paddlefish, have primarily cartilaginous skeletons, but retain some bony elements.
  • The (a) sockeye salmon (Actinopterygii) and (b) coelacanth (Sarcopterygii) are both bony fishes of the Osteichthyes clade.

• Characteristics of Vertebrates

  • The traditional groups include Agnatha, Chondrichthyes, Osteichthyes, Amphibia, Reptilia, Aves, and Mammalia.
