Animal scales are for protecting it from stuff like preditors or branches/twigs
The animal that has moist skin with no scales are amphibians.
There are several species of toad that live in the desert.
They need moist on there scales and they eat fish
An animal that can live on land and water is called an amphibian.
Some of the adaptations that allow fish to live in the water are gills, fins, and scales. The gills allow the fish to live in the water. The gills allow the fish to extract oxygen from the water. The fins allow the fish to swim through the water and help it stear itself. For the scales I'm not sure!
I don't think that there is an animal that can live without water...A camel can live the longest without water but cannot completely live without water.... i will search this up but probaly germs
Gills, fins, and scales.
