Where it is Seen?
This species is distributed throughout the desert areas of Australia, throughout Adelaide and mainland Victoria where it is hot and humid.
The smooth knob-tailed gecko thrives in different ranges of habitat, including open woodlands, open deserts, sand-plains, dune fields, grasslands, or in arid or semi-arid places. They are often seen underground where they burrow.
Behavior and temperament
This reptile is nocturnal that loves to dwell in their self-made shelter or other animals’ burrow. They would find their prey at night, especially after the rain, where almost insects are outside. Compared to other gecko species, the smooth knob-tailed gecko has the ability to withstand lower temperatures; that is why going out at night is an advantage for them.
During a sunny day, they spend their time laying on a rock basking, especially after eating because it is a way for them to digest their food easily. A way for them to show excitement and aggressiveness is through waving their tails. When they are threatened, they sway their bodies, wind their tails, bark loudly, and they attack their predator with an open mouth.
The smooth knob-tailed gecko is an insectivore where their prey consists of only insects such as cockroaches, scorpions, centipedes, spiders, grasshoppers, beetles, caterpillars, and smaller geckos.
Breeding and Reproduction
The mating season for the smooth knob-tailed gecko is around October and March, which are considered as the warm months. An indication that a female knob-tailed gecko is ready to breed if it shows receptive behaviors towards the males for them to mate. However, females who are not yet ready to breed would run away, or they will attack the male.
After mating, the eggs will be formed around 4-9 weeks and expect that these eggs will hatch after 8 weeks as long as the eggs are exposed to at least 28-29°C. The hatchlings will shed their skin within 24 hours after the eggs cracked before they push themselves upwards, using their tiny legs to see the world.
Size and Weight
These reptiles are measured from their snout until their tail’s length. They have an average size of 8-10 centimeters (3.1–4 in). If they dropped their tail, their size is decreased by 1 inch. The females tend to be larger than males.
This is the type of gecko that has quite a short lifespan compared to other geckos. Like other animals taken into captivity, they tend to have a lifespan longer than they are in the wild. The oldest knob-tailed gecko recorded in captivity is about 15 years old, while research shows that its lifespan in the wild will only reach up to 8 years because of some destructive factors.
Like other reptiles, knob-tailed gecko also shed their skin occasionally. Females tend to shed their skin more often, especially before they lay their eggs. For them to shed easily, the proper humidity level should be maintained.
If there is a problem with humidity, there is a possibility that they will shed in pieces and that there will be retained skin. This species will eat their skin after shedding to recycle nutrients found on the shredded skin.
The improper humidity level is the common cause of stuck shed. If the environment is too dry and too wet, expect that your pet will have a hard time shedding. If this happens, don’t touch them and try removing the skin because you might hurt their delicate skin. Increase the humidity level by spraying their tank with water.
This happens when the food given to them is large enough that their body lacks the right temperature to digest and thermoregulate it. To address this issue, make sure to give them just the right size of food and see to it that the temperature level is at the optimum level.
Metabolic bone disease
This is a common disease to reptiles, especially when they lack a certain nutrient. Since they only feed on insects, it is advisable to feed the insects with vegetables so that when the knob-tailed gecko will eat those insects, the nutrients in the insects will also be absorbed in the reptile’s body. There are also supplements found in the market that you can mix in their water or food so that the nutrients will be totally absorbed by their bodies.
Blister skin disease
It may be difficult to confirm if your pet has blister skin disease because of one of their skin colors. You may need to check their skin properly for any signs. The best way to see any blisters is to handle them and check their skin one by one. Blister disease shouldn’t be ignored because this causes pain and great irritations to your pet. In extreme cases, their skin will be wounded and will be prone to infection that can be fatal.
