Species description
Geographical Origin and Habitat: Varanus glauerti is endemic to the Kimberley region of Western Australia. It specifically frequents sandstone gorges, rocky escarpments, and adjacent forest areas, showing a strong evolutionary adaptation to life on vertical cliff faces.
Taxonomy and Genetics: Described by German herpetologist Robert Mertens in 1957. It belongs to the Varanidae family and the subgenus Odatria. It is genetically distinct, with no recognized subspecies, and represents an evolutionary peak in dwarf monitors.
Behavior and Habits: Active, diurnal, and extremely fast. While naturally shy and cautious, they are incredibly curious and intelligent. They are superb climbers (both saxicolous and arboreal) that use their long tail for balance during high-speed leaps.
Morphology: Features an elongated, slender body reaching up to 80 cm in total length, with the tail accounting for nearly two-thirds of the size. The pattern is striking, with a grey-black background, white-to-yellow ocelli, and banded tail patterns.
Care, breeding and tankmates
Terrarium Setup: A spacious enclosure of at least 400-500 liters is required for a single specimen or pair. Include rock walls (securely anchored), stacks of slate tiles, hollow logs, and vertical climbing structures to utilize vertical space.
Lighting and Heating: Requires high heat. Provide a localized hot basking spot of 45-50°C using halogen bulbs, with ambient day temperatures of 28-32°C. High-output linear UVB lamps (10-12% or metal halide lamps) are mandatory for survival.
Humidity and Hydration: Maintain ambient humidity at 40-60%. Crucially, provide deep substrate and humid hiding boxes filled with moist moss or soil (65-75% humidity) to aid shedding. A shallow fresh water bowl is necessary.
Feeding and Supplementation: Strictly insectivorous and carnivorous. Feed crickets, dubia roaches, locusts, and occasional silkworms. Dust insects with high-quality calcium and D3 supplements three times a week, and multivitamins weekly.
Compatibility: Can be housed in pairs or trios (one male, two females) in very large setups. It is critical to provide multiple basking sites so submissive individuals can access heat and light without facing territorial aggression.
Health and Common Diseases: Obesity is a major risk in captivity due to lack of exercise and overfeeding. Metabolic bone disease (MBD) will develop rapidly without proper UVB/calcium. Ensure toes are free of stuck shed to prevent toe loss.

The catalog's scalar value is 25 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 25 cm for this species, recorded as snout–vent length (SVL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
