Nephrurus levis

Nephrurus levis, commonly known as the three-lined knob-tailed gecko, smooth knob-tailed gecko, or common knob-tailed gecko, is a native Australian gecko species. The smooth knob-tailed gecko is part of the Carphodactylidae family, a family endemic to Australia. A common, alternative, name for this family is barking geckos due to the loud barks they make during threat displays, which includes swaying their bodies, winding their tail and attacking with an open mouth. There are multiple sub-species of Nephrurus levis, these include N.l. levis, N.l. occidentalis and N.l. pibarenis. Its aboriginal name is Illchiljera.
