The common term for an amphibian that can live on both land and water is a frog. Frogs are highly adaptable creatures that primarily spend their early life stages in aquatic environments, where they undergo metamorphosis from tadpoles to adult frogs. As adults, frogs can live in various terrestrial habitats. They are known for their distinctive vocalizations, moist skin, and unique life cycle, which involves both aquatic and terrestrial phases. Frogs contribute significantly to ecosystems as both predators and prey.
