The answer to the question about where amphibians live is letter B or part land and part water. It is a known fact that all amphibians usually start their lives in the water with their gills and tails. As soon as they grow, develop and mature, they then develop their lungs and legs so they can also live on land.
There are approximately 4,000 various kinds of amphibians in the world such as blindworms, caecilians, frog, newts, salamanders and toads. That being said, amphibians can also live in the desert and even salt water. A perfect example of an amphibian living in salt water is the crab-eating frog which has the ability to contain its urine in its body so as to help it maintain a proper salt balance internally.
