Amphibians are a class of cold-blooded vertebrates that spend their lives both in water and on land. They are characterized by their smooth, moist skin, which allows them to breathe through their skin. Amphibians undergo metamorphosis, starting as aquatic larvae and developing into terrestrial adults. They are important indicators of environmental health, as they are sensitive to changes in their habitat. Unfortunately, many amphibian populations are declining due to habitat loss, pollution, and disease. Some well-known amphibians include frogs, toads, salamanders, and newts. Despite their challenges, amphibians continue to fascinate scientists and nature enthusiasts alike.
