About Varanus kingorum
Varanus kingorum: Kings' Monitor
Kings' monitor, scientifically known as Varanus kingorum, is a small lizard species belonging to the Varanidae family and is native to Australia. Commonly referred to as Kings' goanna or Kings' rock monitor, this species is distinguished by its relatively small size, reaching up to 40 cm in total length. Its coloration is primarily reddish-brown, with juveniles exhibiting a black reticulum that matures into dark flecks as the lizard ages.
Habitat and Distribution
Varanus kingorum is endemic to the northwestern parts of the Northern Territory and the northeastern regions of Western Australia. Its preferred habitat includes rocky outcrops, areas with rock exfoliations, slopes with open bushland and shrubs, and grasslands, where boulders and crevices provide essential shelter and microhabitats.
Behavior and Diet
This species is characterized by its extremely shy nature, typically retreating into rock fissures and small crevices when it senses a threat. A notable behavioral trait is the use of its long tail to prod insects out of inaccessible hiding places, a behavior observed in both adult and young monitors, suggesting it is instinctual.
Reproduction and Diet
Kings' monitor is oviparous, reproducing by laying eggs. The incubation period for these eggs can range significantly, from 89 to 126 days, particularly when maintained at temperatures around 29°C. Their diet appears to consist exclusively of insects, including common prey such as locusts and termites, as well as insect eggs.
