amphibian physiology

Amphibian physiology encompasses traits that allow life both in water and on land. They breathe through their skin and lungs, with skin needing moistness to absorb oxygen effectively. Amphibians have a three-chambered heart that helps circulate oxygenated and deoxygenated blood efficiently. Their limbs are adapted for swimming and walking. They are ectothermic, meaning their body temperature depends on the environment. Amphibians also undergo metamorphosis, transitioning from aquatic larvae (like tadpoles) to terrestrial adults. Their physiology enables them to thrive in diverse habitats, playing vital roles in ecosystems as both predators and prey.
