Being amphibians, most of them hatch from eggs laid in water into aquatic tadpoles, which then metamorphose into terrestrial frogs. Their skins are permeable and very sensitive to pollutants, so they are very good bio-indicators of the state of health of an eco-system where they occur. This makes frogs very useful in assessing whether wetlands, for example, are polluted. If there is pollution, you won’t find any frogs there. Read More
