There are so many snakes in this world that when in the search there may be millions of species. Snake is a reptile (a reptile) is a group of vertebrate animals that are cold-blooded and have scales that cover their bodies. Reptiles are tetrapods (animals with four limbs) and spawn an embryo egg enclosed by an amniotic membrane. Today they live every continent except Antarctica, and today they are grouped as follows:
Order of Crocodilia (crocodile, garhial, caiman, and alligator): 23 species
Order of Sphenodontia (tuatara New Zealand): 2 species
Order of Squamata (lizards, snakes and amphisbaenia ("worm-lizards")): about 7,900 species
Order Testudinata (tortoises, turtles, and terrapin): about 300 species
Experts say in his findings that some reptiles are more closely related to birds than they are to other reptiles (crocodiles are more closely related to birds than they are to lizards), many modern scientists prefer to make Reptilia into a monophyletic grouping and also include birds, which when it contains more than 10,000 species or species.
