Main Difference

Amphibians and Reptiles are two basics classed of living organisms. Most of the time people mixed the organism belonging from these two different classes due to their basic similarity and which is that both these classes possess cold-blooded animals. Amphibians specifically differ from the Reptiles as the organisms belonging from the Amphibian class are usually born in the water, they spend half their life on the water and other half living on the land. Common examples of Amphibian animals includes Salamanders, toads, frogs, etc. Amphibians are the vertebrates and are found in a variety of different ecosystems such as terrestrial, tonsorial, aquatic, freshwater, etc. On the other hands, Reptiles are the vertebrate and cold-blooded animals that live both on land and water. Reptiles are four-footed crawling animals. Reptiles lay eggs on land. Their eggs are usually covered with the thin protective layer. Reptiles do possess hard scales on their body. Common examples of famous Reptile animals includes crocodiles, snakes, lizards, etc.

What is Amphibian?

Amphibians are the basic class of living organisms that includes vertebrate and cold-blooded animals. The word Amphibian refers to the unique ability of these organisms. Amphibians are capable of living both in the water and on land. Most of the Amphibians usually spend half of their life living under water and remaining half living on the land. Amphibians are cold-blooded animals which mean they possess the ability to maintain their body temperature according to the environment. They are found in a variety of freshwater, aquatic, forests and territorial ecosystems. Common amphibians include frogs, toads, and Salamanders. They reproduce by external fertilization. The female eggs and male sperms both are fused inside the water and the eggs produced remain in the water until they hatch. The amphibian’s egg possesses smooth gel-like layer on them. In early stages of development, they breathe via gills inside the lungs. They pass through various developmental stages process known as metamorphosis in which the development of lungs and other adult shape and part are considered. They have smooth, sticky and slippery skin which possess glands for secretions. Amphibians possess short limbs and webbed foot which helps them in jumping and swimming both. Amphibians do not possess sharp teeth and long nails like reptiles and other animals. They are highly poisonous in nature and can secrete toxic secretion for killing and regarding defending their selves.


What is Reptile?

Reptile is the class of living organisms which includes vertebrates and cold-blooded animals. Reptiles mean the crawling animals. Most of the reptiles do not possess limbs, and they crawl like snakes and various kinds of lizards. Other reptiles possess strong four-footed limbs that help them in swimming and running. Reptiles possess hard scales on their skin which keep them safe and it kind of protective layer. Skin is beneath the scales and is very hard. Reptiles are also cold blooded animals which mean that they can also control their body temperature. Reptiles lay their eggs on land. Their eggs possess thick leathery covering on them as keeping moisture and work as a protective layer too. Reptiles, unlike amphibians, does not undergo metamorphosis.
