  • Domain
  • Kingdom (Animalia) - organisms that can live on their own.
  • Phylum (Chordata) - organisms with a backbone
  • Class (Mammalia) - organisms with fur or hair and milk glands
  • Order
  • Family
  • Genus
  • Species
• Classification of Animals - Vertebrates - with backbone - Invertebrates - without backbone
• Class Agnatha Jawless Fishes e.g. parasites and scavengers fishes such as lampreys and hagfishes

• Estimated 9000 species of Aves are present in the terrestrial animal kingdom
• Class Chondrichthyes

• Class Chondrichthyes


  • sharks
  • stingray

• Class Osteichthyes


  Includes all bony fishes. Like all fishes, Osteichthyes are cold-blooded vertebrates that breathe through gills and use fins for swimming
• Class Reptilia (reptiles)


  Includes many diverse species that are classified into four living clades
• Living clades of Class Reptilia

  • Crocodilia (crocodiles and alligators)
