More About amphibians

Amphibians have been on Earth for a long time. They first came about over 300 million years ago. They are very special because they can live in two worlds. They are part of the food chain and help keep nature in balance.

Amphibians help us by eating pests like bugs. They also show us if the water is clean. If they are sick, it means the water is not safe. This helps us take care of our water.

Some amphibians can live in many places. They can be found in forests, ponds, and even deserts! They are very interesting and can teach us a lot about nature.
