Varanus pilbarensis is a small-sized monitor lizard, typically reaching a snout-vent length of up to 170mm in adults (approximately 470mm including the tail). Compared to other available monitor species, it falls on the smaller end of the size spectrum.

​

The species is characterized by its long tail, which can be twice the length of its snout-vent measurement. Additionally, males exhibit cream-colored striping on the tail and a cream-colored throat, which is more pronounced than in females.

​

In terms of coloration, V. pilbarensis typically displays an orange to bright reddish-brown hue with light greyish spotted banding patterns. The colour and patterns tend to be more prominent in adult males, and juveniles also exhibit strong patterns and coloration.

​

The distribution of Varanus pilbarensis is confined to the north Pilbara region of Western Australia.

Northern Pilbara Rock monitors are terrestrial, rock-inhabiting species (saxicolous) that are commonly found in boulder piles within rocky ranges and highly eroded plateaus. The region is characterized by dry arid to dry grassland habitats.

​

V. pilbarensis was previously considered a relatively rare species within the Australian reptile hobbyist community, but it has recently experienced a resurgence in popularity.

​

In terms of keeping them in captivity, they possess a personality similar to that of most other rock monitors. They tend to exhibit a relaxed temperament once they have acclimated, readily adapting to human interaction and accepting tong feeding.

​

They are highly active on a daily basis, constantly exploring their environment, and they thrive when kept in small groups. It is important to exercise caution during feeding time due to their strong feeding response.

​

They are relatively easy to care for and breed, requiring enclosures of small to medium size. Although they enjoy climbing rock walls, the enclosure dimensions do not need to be as tall as those for arboreal species.

Providing a pile of medium-sized rocks or stacked tiles for them to move through and hide in can create an aesthetically pleasing enclosure setup.

​

Enclosure size: A minimum enclosure size of 90cm in length and 60cm in depth is recommended for a pair or trio of V. pilbarensis.

​

Substrate and furnishings: A substrate of sand or large pebbles is suitable, along with an abundance of hiding places such as hollow logs and stacked flat rocks. Providing a secure and confined space contributes to the animal's sense of security.

​

Temperatures and lighting: Adequate UVB lighting is essential. An ideal setup includes a basking spot with a bright lamp directed onto a rock or tiles, maintaining a temperature range of around 50-65°C. The rest of the enclosure should provide an ambient heat gradient ranging from 28-33°C during the warmer, active months.

​

Humidity: While V. pilbarensis originates from an arid environment, they benefit from occasional light misting and the provision of a humidity hide.

​

Feeding: The primary diet for V. pilbarensis consists of crickets, wood roaches, and various insects, with regular dusting of calcium powder and vitamins. Occasional additions to their diet can include chopped pinkie mice, lean turkey or chicken mince, chopped chicken hearts, boiled chicken egg, quail egg, and chopped day-old quail. A well-balanced variety of food sources is recommended.

​

Life span: V. pilbarensis is typically recorded to have a lifespan of greater than 8 years in captivity.
