This means that amphibians can not regulate his body temperature. For that, amphibians need the sun to keep warm. Initially amphibious life began in the waters and make breathing with gills. Along with the growth of lung and legs develop and amphibians can walk on land.Amphibians are found throughout the world except the poles. They occupy a number of habitats as varied as the rain forest, ponds, and lakes. They are also in the grassy area on the slopes of high mountains, even in the desert.
