Herpetology as a branch of science seems to have it's roots based on the ancient tendency to group together all creeping animals. The study of these animals in a laboratory setting is made easier by the fact that many Herpetiles are very easy to maintain and breed in captivity. They are widely used in physilogical teachings. Herpetological research also includes the extraction and study of venom and it's effects. All Herpetiles are Vertebrates.
Amphibians are a class of animals that have skin poison glands and mucous glands.
The skin also has no feathers, scales, or hair. The living amphibians include Toads and Frogs , Salamanders, Newts, and Caecilians . Most amphibians start their life as aquatic larvae, and in subsequent stages metamorphise into their final adult stage. Reptiles are an animal class of air breathing vertebrates that have scaley bodies and internal fertilization. They fall within an intermediate position of evolutionary development between the Amphibians and the Mammals and Birds .
