At a glance

A small, big-headed gecko of the sandy deserts and grasslands of inland Australia. It shelters in a burrow by day and hunts insects and spiders on open ground at night. It is harmless to people.

Identification

Look for an oversized head, very large dark eyes and a short tail that ends in a small knob. The body is reddish to pinkish brown, crossed by a few pale bands and dotted with tiny white tubercles. The legs are long and thin for a gecko, so it can stand with its body held well off the ground.

01Large head. The head is wide and rounded, out of proportion to the small body.
02Knobbed tail. The tail is short, plump and finished with a small round knob.
03Pale bands and white dots. Narrow light bands cross the head and body; rows of small white scales run along the back.

Size

Adults measure about 3 to 4½ inches (8–11 cm) from snout to tail tip. Much of that length is head and body, because the tail is so short.

Range & habitat

The smooth knob-tailed gecko lives only in Australia. It ranges across the arid and semi-arid interior, with records from Western Australia, the Northern Territory, South Australia, Queensland and New South Wales, from the Pilbara to the Simpson and Strzelecki dune fields.

It uses open country: sandy desert, sandplain, spinifex and tussock grassland and low shrubland. At Uluṟu–Kata Tjuṯa National Park it is found in the more open parts of the park.

Diet & predators

Knob-tails are nocturnal hunters. They leave the burrow at dusk and stalk prey across open sand. The diet is mostly insects and spiders, and it sometimes includes smaller geckos. When excited by prey, they wave the short tail.

Behavior & seasons

This gecko spends the hot part of the day in a burrow and becomes active at night. If a predator catches it, it can drop its tail to distract the attacker; a new tail grows back.

It is a secretive and nervous animal, and it does not tolerate frequent handling.

Reproduction

The smooth knob-tailed gecko lays eggs. Detailed figures on clutch size and timing in the wild are not given in the sources we used, so we do not list them here.

Conservation

The species has a very large range across inland Australia and is listed as Least Concern. Much of its habitat is remote rangeland and desert.

In captivity

Knob-tails are kept by experienced hobbyists. They need a dry, desert-style enclosure with deep, slightly damp sandy soil — at least 4 inches (10 cm) — so they can dig burrows that do not collapse. A heat source warms the ground, and they are fed live insects at dusk.

They are best treated as animals to watch rather than handle. For general advice on reptile keeping, see our pet care guides.
