What is the difference between a mammal and a reptile?
The main difference between mammals and reptiles is the way they regulate body heat. Mammals can produce body heat while reptiles need external heat source such as the sun. That is why most reptiles will bask in the sun to get warm. Mammals give birth to live young while reptiles lay eggs.

How do reptiles control their body temperature if at all?
Reptiles use the environment to regulate their warmth. This strategy helps them conserve energy in the cold and rapidly ramp up their body temperature in the heat, but it also makes them particularly sensitive to global warming. Reptiles warm up just as simply, by basking in the sun.
