American bullfrogs (Rana catesbeiana) are known to eat snakes, fish, rodents and other bullfrogs. Most areas with high amphibian diversity have a few common characteristics, namely warm climates with high annual rainfall. One of the most important characteristics of animals is how efficiently they gather and utilize oxygen, the molecular fuel that powers metabolic processes. The embryos formed in the amphibian eggs soon give way to the larval forms called tadpole, whose physical characteristics are adapted to the aquatic environment: long tails, absence of legs, round mouth and gills. Also, reptiles have scales on their body and function to retain Characteristics of Class Amphibian are given below: 1) The representatives of class Amphibia thrive well both on land and in water i.e. Amphibians spend part of their lives on water and part of their lives on land. 2) Amphibians are cold-blooded or exothermic animals. Characteristics of Amphibians As tetrapods, most amphibians are characterized by four well-developed limbs. While most frogs and salamanders deposit their eggs directly into the water, some species have adapted methods for terrestrial egg deposition. Amphibians are a class of animal that represents a crucial evolutionary step between water-dwelling fish and land-dwelling mammals and reptiles. Licht (1975 ) reported that R. pretiosa tadpoles at low altitudes had longer larval periods and transformed at twice the body size of high‐altitude species.

When they mature into frogs, they undergo numerous physical and biochemical changes, such as growing a large mouth and a tongue; losing gills; developing lungs; growing front legs; synthesizing new visual pigment in the eyes; and developing oxygen-binding hemoglobin protein in the blood. Additional characteristics of amphibians include pedicellate teeth—teeth in which the root and crown are calcified, separated by a zone of noncalcified tissue—and a papilla amphibiorum and papilla basilaris, structures of the inner ear that are sensitive to frequencies below and above 10,00 hertz, respectively.
