A cold-blooded vertebrate of the class Reptilia; an amniote that is neither a synapsid nor a bird.
"The biologist carefully examined the scaly skin and cold blood of the lizard to confirm it was a true reptile rather than a mammal or bird."
Creeping; moving on the belly, or by means of small and short legs.
"The lizard moved slowly across the warm rock, its body dragging along as it crept toward the sun."
