Species description
Geographical Origin and Habitat: The Indonesian Blue-tongued Skink (Tiliqua gigas gigas) is native to the tropical rainforests, damp woodlands, and coastal regions of Indonesia, particularly New Guinea and surrounding islands. Unlike Australian blue-tongued skinks that thrive in arid environments, this subspecies requires a warm and highly humid habitat, sheltering under forest debris, decaying logs, and within damp soil layers.
Taxonomy and Genetics: Belongs to the family Scincidae and the genus Tiliqua. It represents the nominate subspecies of Tiliqua gigas. Genetically, it is adapted to tropical monsoon climates. Morphologically, it is distinguished from Australian species by its longer tail, more slender body profile, and distinctively solid black limbs.
Behavior and Habits: Diurnal, terrestrial, and opportunistic. It spends the day foraging, digging in the soil, and resting in dark shelters. When threatened, it displays a classic defense mechanism: opening its mouth wide, puffing up its body, and sticking out its vibrant blue tongue while producing a loud hiss. It can become docile with regular gentle handling.
Morphology: A large lizard reaching an adult length of 50 to 60 cm. It features a robust, elongated torso supported by short legs with well-defined claws. The head is large, wedge-shaped, and barely distinct from the neck. Dorsal coloring is typically gray, brown, or olive-green with dark brown or black crossbands. The legs are solid black.
Care, breeding and tankmates
Terrarium Setup: A spacious enclosure measuring at least 120x60x60 cm is necessary for a single adult. The substrate must be deep (10-15 cm) to allow burrowing; a mix of cypress mulch, sphagnum moss, and coconut soil is ideal for maintaining moisture. Furnish with large cork bark rolls, heavy branches, and hiding spots on both the warm and cool sides.
Lighting and Heating: Diurnal skinks require high-quality UVB and heat lamps. Provide a 10.0 UVB bulb to prevent calcium deficiencies. Establish a thermal gradient: a basking spot of 32-35°C, a cool side of 24-26°C, and night temperatures around 20-22°C. Never use heat mats as sole heat sources, as they can cause burns.
Humidity and Hydration: Needs a high humidity level of 70% to 80%. Mist the enclosure once or twice daily. Providing a large, heavy water bowl is mandatory; the skink will soak in it, which is crucial for a successful skin shed. Change the water daily, as they often defecate in it.
Feeding and Supplementation: Strictly omnivorous. Adults require a diet composed of 50-60% leafy greens (dandelion greens, endive, escarole), 30-40% proteins (live crickets, dubia roaches, snails, or high-quality grain-free dog food), and 10% fruits (berries, squash). Dust food with calcium powder every other feeding and calcium plus D3 weekly.
Compatibility: Solitary animals. Blue-tongued skinks are highly territorial and must be housed alone. Housing multiple individuals together will lead to severe territorial fighting, resulting in broken limbs, missing toes, and potentially fatal wounds.
Health and Common Diseases: Prone to Metabolic Bone Disease (MBD) due to insufficient UVB or calcium. Stagnant moisture without ventilation can lead to scale rot or respiratory infections. Retained shed on toes and the tip of the tail is common if humidity drops too low, leading to constriction and necrosis.

The catalog's scalar value is 34.3 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 34.3 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.
