Amphibians are a unique class of cold-blooded vertebrates, such as frogs, toads, and salamanders, known for their "double life"—spending part of their life cycle in water and part on land. They typically hatch from jelly-like eggs as aquatic larvae with gills, then undergo metamorphosis to develop lungs and legs as terrestrial adults. Beyond these common traits, amphibians are highly sensitive to environmental changes due to their semi-permeable skin, which they use for breathing and moisture absorption.
