Amphibians

Amphibians are fascinating animals whose name means “double life.” Most begin life in water, breathing through gills like fish.

As they grow, their bodies transform through a process called metamorphosis. They develop lungs and limbs that allow them to live on land.

This group includes frogs, toads, salamanders, and caecilians. While they may look different, all amphibians share some key traits.

They are cold-blooded, meaning their body temperature changes with their surroundings. They have moist, smooth skin that helps them breathe, along with their lungs.

Because their skin dries out easily, amphibians live in damp places like ponds, wetlands, and forests. Even those that spend time on land return to water to lay their jelly-like eggs, which need moisture to survive.

Over time, amphibians developed lungs, stronger limbs, and sharper senses to survive on land. Because their thin skin absorbs substances from the environment, amphibians are easily affected by pollution or climate change.

Though small, amphibians are vital to ecosystems. They help control insect populations and serve as food for other animals.
