What are amphibians?

Amphibians are nature’s switchers, animals that can live in both water and on land like a tiny frog wearing waders one minute and boots the next.

Think of them as the bridge between fish and lizards. They do not have scales like snakes, nor fur like dogs. Instead, they usually have smooth, moist skin that feels cool and wet to the touch, similar to a fresh jellybean or a damp sponge. This special skin is their secret tool because it helps them breathe when they are resting in shallow puddles.

Amphibians spend most of their early lives underwater as babies called larvae. They look like tiny fish with gills to pull oxygen from the water. As they grow up, something exciting happens: they change shape! This process is called metamorphosis. It is like a caterpillar becoming a butterfly, but for frogs and salamanders. Their tails might shrink or disappear, legs pop out, and their lungs develop so they can breathe air.

Most adult amphibians move to land, but they never truly leave the water. They must stay near ponds or damp forests because their skin dries out quickly in the sun. If you find a frog on your sidewalk after rain, it is there because it wants to drink through its skin like a straw! Common friends include frogs, toads, and salamanders. They are cold-blooded too, meaning they need warmth from the sun to get their energy up for jumping or swimming.

They are nature’s swimmers who graduated to walking.
