Usually, found in water or damp places. Mention similarities between reptiles and amphibians. A few species of salamanders (for example, the axolotl) never metamorphose to the adult stage, and although they may develop lungs for air breathing, they retain external gills throughout life. Towards the end of the Permian Period and the Triassic Period, the amphibians started having competition with proto-crocodiles which led to their drop in size in the temperate zones or leaving for the poles. While reproduction of any living being is a natural course, in the case of reptiles, it is dependent on temperature to a large extent. These amphibians were around five meters long in length, which is rare now. First, let's get how they are alike out of the way: Amphibians and reptiles are vertebratesanimals with backbones.

(Amphibians were able to hibernate during the winter whereas crocodiles could not, allowing the amphibians in higher latitudes protection from the reptiles.). They are ectothermic and use camouflage to protect themselves from predators. Contraction of this muscle pulls on the liver and results in expansion of the lungs. They can live both inland and in water. Because their metabolic rate is much lower during winter, adequate gas exchange can be provided entirely by the skin in either terrestrial or aquatic habitats. More than 62,000 vertebrate species have been identified.

Fish have a single circuit for blood flow and a two-chambered heart that has only a single atrium and a single ventricle (figure a). Reptiles are more evolved than amphibians concerning the structure of their limbs. Another exception to the usual pattern of respiratory development is seen in the Plethodontidae family of salamanders, which lose their gills upon metamorphosis but never develop lungs as adults; instead, gas exchange is conducted entirely across the skin.

Students should keep in mind that all reptiles and amphibians also share some common features such as dry skin (instead of hair), scales (or feathers), lungs (instead of a diaphragm), and laying eggs (excluding live birth). Reptiles have scales, which act as a sort of armor to physically defend the body. Reptiles are cold-blooded animals whose skin is covered by scales, whereas amphibians are those whose skin lacks scales and is poisonous.

The Diapsida split yet again into two lineages, the lepidosaurs (which contain modern snakes, lizards and tuataras, as well as, debatably, the extinct sea reptiles of the Mesozoic) and the archosaurs (today represented by crocodilians and birds only, but also containing pterosaurs and dinosaurs). The reptiles (including dinosaurs and birds) are distinguished from amphibians by their terrestrially adapted egg, which is supported by four extraembryonic membranes: the yolk sac, the amnion, the chorion, and the allantois ().The chorion and amnion develop from folds in the body wall, and the yolk sac and allantois are extensions of the midgut and hindgut respectively.

In addition, most of the reptiles lay eggs except pythons and boas, which give birth to young ones. When they feel threatened or sense danger, they can crawl out of the water quite effortlessly with the help of their pectoral limbs. Figure 2. By the time the larva has reached adult form, the lungs have assumed the respiratory function of the larval gills. The function of the skin is also different in reptiles and amphibians.
