Nephrurus levis
An Australian endemic gecko with a large triangular head and a short, leaf-shaped tail ending in a knob. Its skin is smooth for the genus, and pale tubercles form bands over a pinkish-grey to purplish-brown ground.
The smooth knob-tailed gecko (Nephrurus levis) is an Australian endemic in the family Carphodactylidae, reaching about 12 cm in total length with a snout-vent length of 8-10 cm. The head is triangular and broader than the body, with large eyes and vertical pupils. The short, flattened, leaf-shaped tail ends in a knob and can be autotomised, though there is only a single cleavage point at its base. The epithet levis means smooth, by contrast with the strongly tubercled Nephrurus asper. It is widespread in arid and semi-arid inland Australia, is nocturnal, and spends the day in a burrow it digs itself. Because Australia prohibits the export of its native wildlife, the only animals in trade are captive-bred descendants of stock exported in the past. Breeding successes have increased in recent years, making it one of the more available species in the genus. It is nervous and easily startled, so keep it in a quiet setting and avoid excessive handling.

At the request of Australia, genus Nephrurus spp. has been listed on CITES Appendix III (effective June 22, 2022). Because it is on Appendix III, registration as an international rare species is not required. Australia prohibits the export of wild animals native to its territory, and specimens in trade are limited to captive-bred individuals. This species is not included in the specific animals listed in the Schedule of the Enforcement Ordinance of the Animal Protection and Management Law, nor is it designated as a specified alien species under the Enforcement Ordinance of the Alien Species Law.

Humidity
40〜70%
Carnivorous: insects, spiders, centipedes, scorpions and other arthropods, plus small vertebrates such as other geckos
Keep the basking spot at 31-32 C, the cool side at 21-27 C and nights above 18 C, with a clear day-night difference. Among knob-tails the smooth-skinned species such as this one prefer somewhat more moisture, so mist the sand directly under the hide to keep its interior damp. Letting the setup dry out completely causes shedding problems and dehydration.
Terrestrial and an active burrower, it needs at least 8-10 cm of sand. Seat rocks and hides on the floor of the enclosure before adding substrate, never simply on top of the sand, so that a collapsing burrow cannot bury the animal. Use an enclosure of about 60 x 45 x 45 cm as a minimum, and around 90 x 45 x 45 cm for larger individuals.
Carnivorous, taking insects, spiders, centipedes, scorpions and other arthropods as well as small vertebrates such as other geckos. In captivity use crickets and dubia roaches as the staple, dusted with calcium and vitamin supplements. Feed hatchlings daily and adults every few days.
Nervous and easily startled. In threat display it stretches its limbs, arches its back, raises and waves its tail, opens its mouth and produces a barking sound. Knob-tails are solitary by nature and will fight if housed together, so keep them singly. Avoid grabbing or handling them often.
Listed on CITES Appendix III as Nephrurus spp. at Australia's request, effective 22 June 2022. Appendix III requires an export permit from the listing state and a certificate of origin from other states; no Japanese registration certificate is needed. Because Australia bans the export of its native wildlife, every legitimately traded animal is captive-bred. The IUCN assesses it as Least Concern.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The average lifespan of Smooth Knob-Tailed Gecko is 10-15 years in captivity. With proper care and nutrition, they can live a long and healthy life.
Smooth Knob-Tailed Gecko typically reaches About 12cm total length (SVL 8-10cm) as an adult. Size may vary depending on care conditions and individual genetics.
Smooth Knob-Tailed Gecko feeds on: Carnivorous: insects, spiders, centipedes, scorpions and other arthropods, plus small vertebrates such as other geckos. Aim for a balanced diet with appropriate feeding frequency.
