Bulgaria is inhabited by 20 amphibian species, which makes the amphibians the least diverse class of vertebrates in the country. They include seven species of newts and salamanders from a single family, Salamandridae, as well as 13 frog and toad species from five families—Bombinatoridae, Bufonidae, Hylidae, Pelobatidae and Ranidae. The most recently classified species are the northern crested newt, identified in 2005, and the Macedonian crested newt, identified in 2007.
