Until 2001, the genus was believed to be monotypic, the single species being the tailed frog (Ascaphus truei Stejneger, 1899).However, in that year, Nielson, Lohman, and Sullivan published evidence that promoted the Rocky Mountain tailed frog (Ascaphus montanus) from a subspecies to its own species.

The tailed frogs are two species of frogs. The species are part of the genus Ascaphus, the only taxon in the family Ascaphidae / æ ˈ s k æ f ɪ d iː /. The "tail" in the name is actually an extension of the male cloaca. The tail is one of two distinctive anatomical features adapting the species to life in fast-flowing streams.

This frog lives in fast-flowing streams and internal fertilisation prevents the sperm from being washed away before fertilisation occurs. [90]

Frogs and toads are broadly classified into three suborders: Archaeobatrachia, which includes four families of primitive frogs; Mesobatrachia, which includes five families of more evolutionary intermediate frogs; and Neobatrachia, by far the largest group, which contains the remaining families of modern frogs, including most common species ...
