Question

Differentiate between amphibians and reptiles.

Answer 1

Hint: All vertebrates can be grouped into five classes. These are - Amphibia, Pisces, Reptilia, Mammalia, and Aves. Aves and Mammalia are warm blooded animals.

Complete answer:
On the basis of their type and purpose, all living beings are categorised and grouped. Some features can alter the body design more widely than others. Time also has a part to play in this. Thus, if a body shape comes into being, it is essentially because it already exists that it can form the impacts of all future design changes. In other terms, earlier in life traits possibly are more fundamental than later in existence. Vertebrates are divided into five classes. These are - Amphibia, Pisces, Reptilia, Mammalia, and Aves.
Amphibians lack scales, mucus in the skin and a heart of three chambers. Breathing happens into the lungs or through the gills. The eggs were laid down. Both in water and on land, these creatures are present. Reptiles have cold blood, scale and lung for breathing. While most of them are three chambers in the heart, crocodiles have four chambers in the heart. They have tough coverings on eggs and need not place their eggs in water, as compared to amphibians. The difference between amphibians and reptiles are given below:

Amphibians	Reptiles
They do not have scales. They have mucus glands in the skin.	They have scales in the skin.
They have external fertilization.	They have internal fertilization.
Their eggs are surrounded by a gel like substances.	Their eggs are covered with tough covering.
They can respire by gills and lungs.	They can respire only by the lungs.
Their skin is porous and smooth.	Their skin is dry and hard.

Note: Amphibians are able to breathe underwater with gills and reptiles can breathe with lungs only on land. Amphibians have soft, sticky skin and reptiles have dry, scaly skin. Some examples of amphibians are the frogs, toads and salamanders. Reptiles contain snakes, turtles, lizards, crocodiles, etc.
