The term for animals that live in both water and on land is "amphibians." Amphibians are a diverse group that includes frogs, toads, salamanders, and newts. These creatures typically begin their life cycles in the water as eggs or larvae and undergo metamorphosis to develop into adults capable of living on land. Unlike reptiles, amphibians possess moist skin facilitating respiration and absorption of water. Their dual habitat makes them sensitive to environmental changes, contributing to their role as indicators of ecosystem health. Conservation efforts are crucial to protect amphibians, as many species face threats from habitat loss and pollution.
