Lacking cold blood
Nonreptilian describes anything not belonging to or characteristic of reptiles—the class of cold-blooded, scaly vertebrates that includes snakes, lizards, turtles, and crocodilians.
The term appears in biological contexts distinguishing evolutionary lineages: nonreptilian ancestors of mammals, nonreptilian vertebrates.
It can also describe features or behaviors: a nonreptilian warmth in her personality.
