Mammals vs. Amphibians: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 17, 2024
Mammals are warm-blooded vertebrates with fur or hair and mammary glands, while amphibians are cold-blooded vertebrates that live in water and on land, typically with moist skin and no scales.

Key Differences

Mammals are characterized by their warm-blooded nature, maintaining a constant body temperature. Amphibians, in contrast, are cold-blooded and rely on the environment to regulate their body temperature.

A defining feature of mammals is the presence of mammary glands for feeding young. Amphibians do not have mammary glands; their young typically undergo metamorphosis from larvae to adults.

Mammals usually have fur or hair covering their bodies, providing insulation and protection. Amphibians are known for their moist, scaleless skin, which aids in gas exchange and moisture absorption.

In terms of reproduction, most mammals give birth to live young. Amphibians generally lay eggs in water, with offspring initially living as aquatic larvae.
