The primary mode of respiration in reptiles is pulmonary respiration, and they cannot respire through the skin. A notable similarity between the two is that both are cold blooded animals ‘“ that is their internal body temperature changes with the environment unlike humans where the temperature remains the same, more or less. Compared to reptiles, amphibians are oviparous, whereas reptiles are oviparous as well as viviparous. Amphibians have smooth, sticky, moist and highly porous skin to perform the various function, whereas reptiles have dry, hard and scaly skin, which guard them in harsh condition. However, there are two known species of venomous frogs, Bruno’s casque-headed frog, and Greening’s frog. The skin of most amphibians is not water-proof unlike reptiles. Usually, found in water or damp places. The main difference between amphibians and reptiles is that amphibians live in aquatic environments during their larval stage and adults migrate to the land whereas reptiles are adapted to live in terrestrial environments.
