5- Has it got scales?

Yes, it has. Then it should be a fish. Remember that some scales cannot be seen with the naked eye and there are some fishes without scales. However, they all breathe in water using their gills and have got fins to help them swimming.

No it hasn’t. Then it should be a amphibian. Amphibians start their lives in water and they use gills to breathe. Then, after a metamorphosis they can live on land because their gills disappear and they develop lungs. They can also breath through their moist skin.
