amphibian metamorphosis

Amphibian metamorphosis is the biological process through which amphibians, like frogs and salamanders, transform from aquatic larvae into terrestrial or semi-aquatic adults. During this transformation, they undergo significant physical changes: gills are replaced by lungs for breathing air, a tail may shrink or be lost, limbs develop, and digestive systems adapt for different diets. This complex process is controlled by hormones, particularly thyroid hormones, which trigger the necessary changes at specific developmental stages. Overall, metamorphosis allows amphibians to adapt to different environments as they grow.
