Amphibians are an important link in the evolutionary chain that connects water-dwelling fish to land-dwelling vertebrates. In addition, they have a primitive lung in comparison to other vertebrates, which links them to the evolution of early vertebrates.
During the Devonian period, more than 370 million years ago, the first amphibians appeared on Earth.
The Chinese giant salamander is the world’s largest amphibian, measuring 180 cm in length.
The smallest amphibian is a frog called Paedophryne amauensis, which measures 7.7 mm.
There are over 6,000 amphibian species known to exist today.
Herpetology is the branch of science that studies reptiles and amphibians.
Because of their permeable skin, amphibians are one of the most vulnerable species to water and air pollution, as well as global warming.
Amphibians Ruled the Earth Millions of Years Ago.
Amphibians Are Among the World’s Most Endangered Animals
Amphibians are strictly ectothermic, meaning they heat up and cool down in response to the temperature of their surroundings.
