What order do snakes and lizards go in?

The major groups of living reptiles—the turtles (order Testudines), tuatara (order Rhynchocephalia [Sphenodontida]), lizards and snakes (order Squamata), and crocodiles (order Crocodylia, or Crocodilia)—account for over 8,700 species.

What came first lizard or snake?

Lizards evolved first. So it looks like snakes evolved from swimming lizards—only later did snakes come back up onto land. Some of the most primitive living snakes—things like boas and pythons—also still have tiny remnants of hind legs and are good swimmers, just like their early ancestors.

Why are snakes and lizards in the same order?

With a collective 8,000 known species, lizard and snake species make up the largest taxonomic order of reptiles, known as squamata, which dates to the age of the dinosaurs. Snakes and lizards are grouped together because they share a significant number of physical, reproductive and metabolic characteristics.

What do snakes and lizards have in common?

As the order name suggests, both snakes and lizards have the same scaly skin. The outer layer of the squamate’s skin is composed of side by side and overlapping scales that do not grow with the animal. Rather, this dry outer layer is dead and must be shed periodically as the squamate grows.
