Introduction to Amphibians

Amphibians, such as frogs and salamanders, have moist skin that aids in breathing. They are ectothermic vertebrates that start life in water and often transition to land. This process, known as metamorphosis, involves significant physical changes. Most amphibians are frogs or toads, highlighting their diversity.
