— AD —
Australia is the native home of the centralian rough knob-tail gecko. Here they live in the center of the country in small areas of the Northern Territory and Western Australia.
Centralian rough knob-tail geckoes are found in deserts, rocky areas, dry woodlands and dry grasslands.
They will shelter under the rock crevices and rocky slabs.
Breeding takes place from October to March in the wild.
During mating the smaller male will virtually climb on the back of the female to allow them to mate.
The female will lay a clutch of two eggs a month after a successful mating. Females may lay multiple clutches within one breeding season.
These eggs incubate for two to three months before they hatch. After hatching they are responsible for their own care.
Their most notable vocalization is a rasping bark.
During the day the centralian rough knob-tail gecko will shelter under a rocky slab. They emerge at night to find food.
