reptiles
Scaled, egg-laying animals
Reptiles is the plural of reptile—cold-blooded vertebrates with scaly skin that typically lay eggs on land.
The class includes snakes, lizards, turtles, and crocodilians.
Figuratively, calling someone a reptile suggests they're cold, calculating, or morally repugnant: That reptile cheated his own grandmother.
