Amphibians are cold-blooded vertebrate animals (same as reptiles) that live part of their lives in water and part on land.
They typically have moist, permeable skin and undergo metamorphosis, transitioning from aquatic larvae (e.g., tadpoles) to terrestrial adults (e.g., frogs and salamanders).
Amphibians are sensitive to environmental changes and serve as indicators of ecosystem health. They play roles as both predators and prey, and their survival is threatened by habitat loss and pollution.
