Do You Know?
Mammals and reptiles are different types of animals. Mammals have fur and feed milk to their babies, while reptiles have scales and usually lay eggs.
Body Covering
Mammals have fur or hair that insulates and protects. Reptiles have tough, scaly skin that prevents water loss and provides protection from predators.
Warm-blooded vs. Cold-blooded
Mammals are warm-blooded and regulate body temperature internally. Reptiles are cold-blooded and rely on external heat sources like sunlight to stay warm.
Reproduction
Mammals give live birth (except monotremes like platypus). Reptiles mostly lay eggs, but some species, like certain snakes, give live birth too.
Heart Structure
Mammals have a four-chambered heart for efficient oxygen circulation. Most reptiles have a three-chambered heart, except crocodiles, which have four chambers like mammals.
Feeding Young
Mammals feed young with milk from mammary glands. Reptiles do not nurse their young, and hatchlings are typically independent immediately after birth.
Breathing Mechanism
Mammals use lungs for breathing, even aquatic ones like whales. Reptiles also use lungs but may supplement oxygen intake with skin or other adaptations.
