¿Qué es un anfibio?

The video explores the defining characteristics and life cycle of modern amphibians, which have two stages: an immature form in water and an adult form on land. It categorizes amphibians into three main groups: anurans, warlords, and hypnophyons, each with unique traits. Amphibians have moist skin, require water for survival, and undergo metamorphosis from larvae to adults. Their eggs lack protective shells, necessitating a water environment for development. Despite evolving from water, amphibians still rely on aquatic habitats for reproduction.
