Animal Biodiversity

Animal Biodiversity or Herpetology is a branch of zoology which deals with reptiles and amphibians. Herpetology is concerned with poikilothermic, ectothermic tetrapods. Amphibians are often sensitive to environmental changes. Some amphibians and reptiles which produce toxins and venoms are useful for the human medicine. Some snake venom is used as anticoagulant which is used for the treatment of heart stroke.
