Amphibians have the ability to breathe over land through lungs and underwater through their skin. While underwater, crocodiles breathe using lungs and need to surface frequently to take in air. The crocodile is the largest land-dwelling reptile in the world. It has a long, narrow snout with a large mouth filled with rows of sharp teeth. The upper jaw is used for biting and the lower jaw for crushing prey.

Is snake an amphibian?
Reptiles include turtle, lizard, crocodiles, snakes while amphibians include frogs, salamander, toads, newts. Both of them are cold-blooded. External heat sources are needed to maintain a body temperature. Their blood circulates at a lower temperature than that of birds and mammals. This means that they need a source of heat to keep their body warm.
Reptiles have no internal heat source, so they have to rely on external sources such as the sun, wind, and water. Birds have a heat-sensing organ in their feathers called the thermoregulatory system. It senses the temperature of the air around them and sends a signal to the brain that tells them when it’s time to cool down.
The brain then tells the heart to pump more blood into the body to warm it up. In contrast, reptiles do not have this heat sensing organ. Instead, they use their skin to regulate their internal temperature by regulating the amount of water in the skin. When it gets too hot, the reptile cools down by shedding its skin and regrowing it.
