Amphibians are tetrapod animals that first evolved on Earth during the Devonian period. Most amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and as such need to keep their skin moist in order to survive. Amphibians are classified as such:
- Kingdom: Animalia
- Superphylum: Deuterostomia
- Phylum: Chordata
- Subphylum: Vertebrata
- Class: Amphibia
