The name of the genus comes from the Greek pseudes (false) and akris (), probably a reference to the repeated rasping trill of most chorus frogs, which is similar to that of the insect.
In the female spring peeper, protruding beyond the lower jaw of the frog sits its snout. Through the use of adhesive pads located on the tips of their non-webbed fingers, spring peepers can stick to particular materials. Males and females are differentiated from one another through the darkening of the skin beneath the jaw in males.

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.
The Pacific chorus frog's name derives from their auditory performance in their mating call. The two-note male can signal a mating call via the two large and round vocal sacs that inflate beneath the chin repeatedly, sounding like a chorus.
