All About Amphibians
Amphibians are members of the class Amphibia. The living ones are frogs including toads , salamanders including newts and caecilians. They are four-legged vertebrates which are cold blooded. Amphibians lay their eggs in water, usually in a foam nest. After hatching they are tadpoles , which live in the water and have gills. The tadpoles change into adults in a process called metamorphosis. When they are adult, they have lungs to breathe instead of gills, and legs. Adult amphibians also use their skin to take in oxygen , and some species of salamanders do not have lungs.
The earliest amphibians evolved in the Devonian from lobe-finned fish which had jointed leg-like fins with digits. They could crawl along the sea bottom. Some had developed primitive lungs to help them breathe air when the stagnant pools of the Devonian swamps were low in oxygen.
They could also use their strong fins to hoist themselves out of the water and onto dry land if necessary. For tens of millions of years, during the Carboniferous and early Permian , amphibia were top predators on land, especially in the low-lying tropical river systems. In drier conditions, they were less effective, and the ancestors of mammals and reptiles the Synapsids and Sauropsids gradually took over the land.
They laid cleidoic eggs , which had hard shells, and could be laid out of water. Most of the large, early, amphibians went extinct in the Triassic period; a few survived to the Lower Cretaceous. The only living amphibiana today are the Lissamphibia. These include the Anura frogs and toads , Caudata salamanders and newts and Gymnophiona caecilians. They are all rather small, compared with mammals or reptiles. The smallest frog and vertebrate in the world is the New Guinea frog Paedophryne amauensis.
