The most common way amphibians move is by crawling hooping and walking on land with their four legs. The only amphibian that does not have legs is the caecilians and sirens. Caecilians slither and burrow like a snake in the ground. Sirens have only two arms and they crawl and slither at the same time with their arms and tail. In the water, all the amphibians swim with their legs and tails.
