(From Wikipedia) Squamata is the largest order of reptiles, comprising lizards, snakes, and amphisbaenians (worm lizards), which are collectively known as squamates or scaled reptiles.
FACT: Venom in reptiles has been determined to have originated in an ancestral squamate, which then differentiated into all the known venomous reptiles!
