Mammals vs. Reptiles: What's the Difference?
Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 28, 2023
Mammals are warm-blooded vertebrates with hair or fur, while reptiles are cold-blooded vertebrates with scales.
Key Differences
Mammals are a class of animals characterized by their warm-blooded nature, which means they can regulate their body temperature internally. Reptiles, on the other hand, are cold-blooded, relying on external sources like the sun to regulate their body temperature.

Mammals typically have hair or fur covering their bodies, which can serve various purposes such as insulation or camouflage. In contrast, reptiles possess scales, which can offer protection or aid in moisture retention.

The way these animals reproduce also varies. Mammals usually give birth to live young, nourishing them with milk produced by mammary glands. Reptiles generally lay eggs, though some species do give birth to live young.

Another distinct difference is in heart structure: most mammals have a four-chambered heart, ensuring efficient separation of oxygenated and deoxygenated blood, while most reptiles have a three-chambered heart.
