reptiles: Reptiles, all members of the class Reptilia, a group of air-breathing vertebrates with internal fertilization, amnion development, and epidermal scales covering part or all of the body. The main groups of living reptiles - turtles (order Testudines), tuatar (order Rhynchocephalia [Sphenodontida]), lizards and snakes (order Squamata) and crocodiles (order Crocodylia or Crocodilia) - have more than 8700 species. Birds (class Aves) share a common ancestor with crocodiles in the subclass Archosauria and are technically the same reptilian lineage, but are treated separately (see Birds).
mammalian: Mammals (class Mammalia), any member of a group of vertebrates that feeds on milk from the mother's special mammary glands. In addition to these characteristic mammary glands, mammals are distinguished by a number of other unique characteristics. Hair is a typical mammalian feature, but it has been lost in many whales except during embryonic stages. The lower jaw of mammals is attached directly to the skull rather than through a separate bone (quadrum) as in all other vertebrates. Three small bone chains carry sound waves through the middle ear.
