Male crested newt rests amongst frogspawn


Amphibians include frogs, salamanders and caecilians. A typical amphibian has a larval stage spent in water during which it breathes through gills, and an adult stage that is less tied to water when they rely on lungs. However, there are some species that skip the tadpole stage and others that keep their gills throughout their life.
