The class Amphibia is composed of only 3 orders. Anura, which refers to tailless amphibians, includes frogs and toads (see Table: Similarities and Differences Between Frogs and Toads). This is the largest order with more than 3,500 species. Caudata refers to amphibians with tailsâsalamanders, newts, and sirensâand has about 375 species (see Table: Some Common Salamanders and Newts).
