"Biology of Amphibians"

Amphibians are a unique group of animals that include frogs, toads, salamanders, and newts. They are known for their life cycle, which typically includes a stage in water (like tadpoles) and a stage on land, allowing them to adapt to both environments. Amphibians have permeable skin that helps them absorb water and gases, making them sensitive to environmental changes. They play crucial roles in ecosystems, serving as both predators and prey. Unfortunately, many amphibian species are threatened or endangered due to habitat loss, pollution, and climate change, highlighting their importance in biodiversity.
