Snakes and Lizards

Snakes and lizards are so closely related that they are both classified into the same order, Squamata. Squamata consists of scaled reptiles including the 6 suborders of Gekkota, Scincoidia, Lacertoidia, Anquimorphia, Serpentes, and Iguania. These include snakes and legless lizards. To clear up a common misconception, legless lizards are not snakes, some identifying characteristics of snakes vs legless lizards are:Snakes have belly scutes that look different from the rest of their body.Snakes do not have eyelids.Snakes have shorter tails. (The tail starts at the cloaka, then to the end of the animal).etcetera.With that out of the way, squamata is the largest reptile order in terms of species, with over 10900 species. It is also the newest order out of the 4.
