The main features of reptiles, according to the four most common means of categorising vertebrates are:

  • they have scaly skin (not scales)
  • as with other vertebrates, they breathe using lungs (as opposed to fish, which use gills)
  • their young may be born live or hatched from eggs
  • they are cold-blooded
