👉 An amphibian is a type of animal that lives in both water and land, typically having a skin that can be divided into three parts - an outer layer called the epidermis, a middle layer called the subcutaneous tissue, and a dermal layer. They have a wide range of adaptations for aquatic and terrestrial environments, including a streamlined body shape to swim efficiently, specialized organs such as gills or lungs for breathing underwater, and sometimes a skin coating that helps them survive in cold water
