Amphibians are the type of animals known for living both in water and on land. This group includes frogs, toads, salamanders, and newts. Amphibians typically have a life cycle that includes both an aquatic larval stage (like tadpoles) and a terrestrial adult stage. They breathe through their skin as well as lungs, depending on their life stage and environment. This dual habitat allows them to exploit different food sources and habitats, but it also makes them sensitive to environmental changes, such as habitat degradation and pollution. Amphibians play vital roles in ecosystems, acting as both predators and prey.
