Varanus acanthurus, commonly known as the spiny-tailed monitor or spiny-tailed monitor, is a species of lizard belonging to the Varanidae family. This monitor is native to the arid and semi-arid regions of northern Australia, where it mainly inhabits rocky areas, savannas and dry bushland. Its common name refers to its distinctive tail, which is covered in spines or pointed scales that provide protection from predators and aid in fat storage.
The Varanus acanthurus is relatively small compared to other members of its genus, reaching between 60 and 70 centimetres in total length, including its tail. Its body is robust and covered with small granular scales, while its colouration varies from brown, yellowish or reddish tones with black spots that form irregular patterns, providing excellent camouflage in its natural environment.
This lizard is an active and opportunistic predator, feeding primarily on insects, arachnids, and small vertebrates, although it may also consume eggs and carrion when the opportunity presents itself. It is known for its diurnal behavior and its ability to climb rocks and trees in search of prey. In addition, it can dig burrows to take shelter from the heat of the day and avoid predators.
The Varanus acanthurus is an oviparous species, laying between 5 and 10 eggs per clutch in holes dug in the ground or rock crevices. The eggs are incubated for several months before they hatch, depending on the ambient temperature.
In captivity, this species is appreciated by reptile hobbyists due to its manageable size and active behavior. However, it requires specific care that mimics its natural arid environment, such as high temperatures, ultraviolet light, and a suitable substrate for burrowing.
