Full Answer

Many amphibians have legs, but they are very weak. The reason they have such weak legs is to help the animal move well both on land and in water. For example, frogs have to front legs that are very short. But they have back legs that are much longer. These rear legs are the frogs primary means of locomotion. When they are on land, they use these legs to propel themselves forward in a hopping motion. When they are in water, these legs help them to be able to swim very quickly.

Another example of an amphibian with weak legs is a salamander. Many salamanders have four small legs that help them to walk on dry land. These feet are webbed for several purposes. The first is to help them swim quickly when they are in water. The second is to help them adhere to surfaces, so that they can climb up trees. Some salamanders have no legs. These amphibians move their body back and forth much like a snake.
