Explanation: 

Detailed explanation-1: -The main difference between amphibians and reptiles can be seen in their physiological adaptations, body covering, mode of reproduction, egg structure and presence/absence of limbs. Reptiles are cold-blooded animals whose skin is covered by scales, whereas amphibians are those whose skin lacks scales and is poisonous.

Detailed explanation-2: -Reptiles have scales, and their skin is dry. Amphibians do not, and their skin is often moist with mucus, which keeps them from drying up.

Detailed explanation-3: -Reptiles are born with lungs, while amphibians are born with gills for breathing under water-where they hatch and spend their early development (growing lungs and legs later). Reptiles have scales, while amphibians have thin, smooth skin. Snakes, turtles, and lizards are reptiles.

Detailed explanation-4: -The main difference between Amphibians and reptiles is that Reptiles are land animals whereas amphibians live both on land and in water. Amphibians can breathe both through gills and lungs while reptiles breathe through lungs only.

Detailed explanation-5: -Amphibians are frogs, toads, newts and salamanders. Most amphibians have complex life cycles with time on land and in the water. Their skin must stay moist to absorb oxygen and therefore lacks scales. Reptiles are turtles, snakes, lizards, alligators and crocodiles.
