How are animals classified that live on land and water?

Animals that live on land and water are classified as amphibians. Amphibians are vertebrates that are able to live both in water and on land. They have a variety of adaptations that allow them to do this, such as lungs for breathing air and gills for breathing water. Some common examples of amphibians include frogs, salamanders, and newts.

Amphibians are an important part of the ecosystem, as they help to control the population of insects and other small animals. They are also a food source for many larger animals, such as birds and snakes.
