Species description
Geographical Origin and Habitat: Native to the savannas, grasslands, and forest edges of Argentina, Brazil, and Uruguay. They are terrestrial and active burrowers, digging deep underground dens.
Taxonomy and Genetics: Family Teiidae. Salvator merianae. Renowned for their high cognitive intelligence, problem-solving skills, and distinct personality.
Behavior and Habits: Diurnal and active. They can be trained to recognize their names or targets. Adults can be very docile with regular handling, but juveniles are often skittish. They go through a defensive phase during puberty ("Tegu-erty"). They undergo a long winter brumation.
Morphology: Massive, heavily built lizard reaching 120-150 cm in length. Mature muscles in males develop prominent jowls (cheek muscles). Skin features beaded scales in a stark black and white banded pattern.
Care, breeding and tankmates
Terrarium Setup: Extremely large, custom-built enclosure (minimum 240x120x120 cm). Provide a deep layer (30-40 cm) of damp substrate (soil, coco-fiber, sand mix) to allow natural burrowing. Include a heavy, giant water basin for soaking.
Lighting and Heating: Provide a strong temperature gradient. Cool side at 24-26°C. Basking spot must reach 40-45°C using a cluster of halogen bulbs. High-output UVB lighting (Arcadia 12% or 14% T5) is mandatory. Night drop to 20-22°C.
Humidity and Hydration: Maintain high humidity (70-80%) to prevent shedding issues. Mist substrate regularly. Provide a clean water basin large enough for the lizard to submerge.
Feeding and Supplementation: Voracious omnivores. Juveniles eat insects, whole fish, and pinkies. Adults consume thawed rats, quail, raw fish, eggs, and fruits (berries, mango). Dust meals with calcium and D3 weekly. Limit fatty meats to avoid obesity.
Compatibility: Solitary. House individually. Cohabitation is stressful and can lead to severe territorial fights or injury.
Health and Common Diseases: Prone to metabolic bone disease (MBD) if UVB/calcium is insufficient. Obesity is a common issue in captivity. Ensure correct brumation parameters.

The catalog's scalar value is 50.1 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 50.1 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.
