One amphibian called the Caudata slithers like a snake. Amphibians that do not have tails, on the other hand, will move in different ways. The means of locomotion for tailless amphibians is hopping or walking.Know More
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.Learn more about Amphibians
Amphibians are cold-blooded vertebrates. They have a backbone, and they maintain their body temperature through external means, such as laying in the sun. Amphibians spend part of their lives on water and part of their lives on land. They have permeable skin, which gases and some molecules penetrate; they also have gills for some portion of their lives.Full Answer >
Most amphibians, animals who live on both land and water, reproduce by laying eggs. A minority of amphibian species, however, reproduces by giving birth to either live young or larvae.Full Answer >
Amphibians live in and out of the water, with many species being found in wetlands or marsh areas. Many amphibians have slimy bodies that need rehydration, which is why many live near a water source.Full Answer >
Most amphibians have three chambers; for example, this is the case with a frog's heart. There are two atria and one ventricle. The anatomy of the chambers keeps the mixing of the bloodstreams to a minimum.Full Answer >
