Reptiles and Amphibians

 

The primary distinguishing feature between amphibians and reptiles is the ability of an amphibian to sustain life underwater for at least part of its life. Amphibians are smoother and moister than reptiles, which are dry and scaly, and need to live close to a water source. Amphibians begin life in water and later mature on land. They are cold-blooded vertebrates, consisting mainly of frogs, toads, and salamanders. Amphibians begin life breathing water through gills, and grow to breathe air through lungs. Reptiles are cold-blooded, have a backbone, lay eggs, are covered in scales, and breathe air through lungs. They generally have short legs and long tails. Modern reptiles include snakes, lizards, and turtles.
