  Source: Wikipedia

  Reptiles (Reptilia) are members of a class of air-breathing, ectothermic (cold-blooded) vertebrates which are characterized by skin covered in scales and/or scutes. They are tetrapods, either having four limbs or being descended from four-limbed ancestors. Modern reptiles inhabit every continent with the exception of Antarctica. Reptiles originated around 320-310 million years ago during the Carboniferous period, having evolved from advanced reptile-like amphibians that became increasingly adapted to life on dry land. Four living orders are typically recognized: Crocodilia: 23 species Sphenodontia: 2 species Squamata: approximately 9,150 species Testudines: over 300 species Aves (birds), which are not cold-blooded or scaly, are not included in this list. Crocodiles are more closely related to birds than they are to lizards, however, so some writers who prefer a more unified (monophyletic) grouping also include the birds: over 10,000 species. Unlike amphibians, reptiles do not have an aquatic larval stage. As a rule, reptiles are oviparous (egg-laying), although certain species of squamates retain the eggs until hatching and a few are viviparous. Many of the viviparous species feed their fetuses through various forms of placenta analogous to those of mammals, with some providing initial care for their hatchlings. Extant reptiles range in size from a tiny gecko, Sphaerodactylus ariasae, which can grow up to 17 mm (0.7 in) to the saltwater crocodile, Crocodylus porosus, which may reach 6 m (19.7 ft) in length and weigh over 1,000 kg (2,200 lb). The study of reptiles and amphibians is called herpetology.
