In amphibians, where are drink patches located?

In amphibians, drink patches are located on the ventral surface. This is significant because the ventral side of amphibians is where the skin is highly permeable and can absorb water directly from the environment. Unlike terrestrial animals that drink through their mouths, amphibians utilize their skin to hydrate, making the ventral surface an important area for this function. The moist skin acts as a drinking surface when the amphibian comes into contact with water. Understanding the unique adaptations of amphibians, including their hydration methods, highlights the differences in physiology compared to other classes of animals.
