Species description
Geographical Origin and Habitat: The Eastern Blue-tongued Skink (Tiliqua scincoides scincoides) is native to eastern and southeastern Australia. It is an extremely adaptable lizard inhabiting open woodlands, grasslands, dry sclerophyll forests, coastal dunes, and semi-urban backyards, where it seeks shelter under fallen logs, rocks, and debris.
Taxonomy and Genetics: Belongs to the family Scincidae, genus Tiliqua. It represents the nominate subspecies of Tiliqua scincoides. Genetically, it is closely related to the Northern Blue-tongued Skink (Tiliqua scincoides intermedia) and the Tanimbar variant, distinguished mainly by minor scale arrangements and coloration patterns.
Behavior and Habits: Diurnal, terrestrial, and solitary. In the wild, it spends mornings basking to raise its body temperature before foraging. When threatened, it flattens its body, opens its mouth wide, and sticks out its bright blue tongue while making a puffing sound. It quickly becomes very docile and tolerates human handling.
Morphology: A large lizard reaching an adult length of 45 to 55 cm. It features a heavy, elongated, somewhat flattened body with short limbs and a thick tail that is roughly half the body length. The head is large and triangular. The coloration consists of dark brown or black crossbands over a gray, cream, or brown base, with a distinctive dark stripe behind each eye.
Care, breeding and tankmates
Terrarium Setup: A horizontal enclosure of at least 120x60x60 cm is required for a single adult. Use a dry substrate that permits digging, such as a 10 cm layer of aspen shavings, cypress mulch, or a topsoil/sand mix. Furnish with hollow cork logs, flat rocks, and hiding spots on both ends of the temperature gradient.
Lighting and Heating: Diurnal reptiles require quality heat and UVB lighting. Provide a T5 or T8 10.0 UVB tube to prevent metabolic bone disease. Establish a basking spot temperature of 32-35°C on the substrate, with a cool side of 24-26°C. Night temperatures can safely drop to 18-20°C without additional heating.
Humidity and Hydration: Maintain moderate humidity levels between 40% and 60%. High humidity is detrimental and can lead to skin problems. Provide a humid hide filled with damp sphagnum moss to assist with shedding. A shallow, heavy water dish must be provided and cleaned daily.
Feeding and Supplementation: Strictly omnivorous diet. For adults, provide 50-60% leafy greens (dandelion greens, collards, escarole), 30-40% proteins (live crickets, dubia roaches, snails, or high-quality canned dog food), and 10% fruits and vegetables. Supplement with pure calcium at every feeding and calcium with D3 weekly.
Compatibility: Strictly solitary and territorial. Never house multiple skinks together, as they will fight aggressively, resulting in severe injuries, loss of toes, tail damage, or death. Cohabitation is only done briefly for breeding purposes under close supervision.
Health and Common Diseases: Metabolic Bone Disease (MBD) is a primary risk if calcium and UVB are lacking. Poor sheds (dysecdysis) on toes and tail can lead to necrosis if a humid hide is not available. Respiratory infections are caused by cold drafts or excessive moisture. Watch for obesity from overfeeding.

The catalog's scalar value is 38 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 38 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.
