* Alligators are reptiles: They belong to the Class Reptilia, characterized by scales, cold-bloodedness, and laying eggs.
* Armadillos are mammals: They belong to the Class Mammalia, characterized by fur, warm-bloodedness, giving birth to live young, and nursing their offspring.
While both animals inhabit similar regions (like the southeastern United States), their biological classifications are very different due to their distinct physical characteristics and life cycle.
