In the United States, there are over 230 amphibians, over 280 reptiles and approximately 800 species of fish. Each of these categories has species represented on the US Endangered Species List. Together, more than 170 amphibian, reptile and fish species are threatened or endangered.
The three modern orders of amphibians are Anura (the frogs and toads), Urodela (the salamanders), and Apoda (the caecilians). The number of known amphibian species is approximately 7,000, of which nearly 90% are frogs.mphibians have a skeletal system that is structurally homologous to other tetrapods, though with a number of variations. They all have four limbs except for the legless caecilians and a few species of salamander with reduced or no limbs.
