Question

what is the importance of amphibian?

Answer 1

you should be more specific...(in which field)

In evolution:
They indicate the transition of animals from water habitat to land habitat.

Answer 2

They are a vital prey item to many other species, therefore an important part of the ecosystem. They are also known as "indicator species" because they are very sensitive to environmental conditions and pollution... The fact that their populations are declining is a major hint to us that we are doing something very wrong. Finally, there are many medicinal uses being discovered every day. Substances from the skin of some frogs are being used to create a pain reliever many times stronger than morphine without the chance of addiction, and one species is known to have anti-HIV properties in it's skin.
