Salvator rufescens

Spacious terrestrial terrarium geared toward a burrower (deep substrate)

Minimum dimensions for ONE adult; bigger is always better, and a custom cabinet-style enclosure is strongly recommended for an animal of this size. A very sturdy terrarium (a powerful, burrowing adult), with a robust hide and a humidification tub. Heating and UVB must be out of reach or protected to prevent burns.

Moderate to high ambient humidity. Too low a level causes shedding problems (dysecdysis), common in this species: keep a deep substrate that is slightly moist in its lower layer, a humidification tub and a large water point. Conversely, avoid a constantly waterlogged atmosphere that promotes skin infections.

Deep, loose substrate (at least 20-30 cm, ideally more) allowing the animal to dig burrows, an essential natural behaviour. Keeping the lower layer slightly moist helps regulate humidity and prevents shedding problems.

Essential. Provide high-output UVB (T5 HO tube, ~10-12%) covering the basking area, with a UV index (UVI) of about 4-6 at the hot spot. Replace the tube every 6-12 months depending on the model. Without adequate UVB combined with calcium, high risk of metabolic bone disease (MBD).

A large container of clean water, wide and stable enough to let the animal immerse and bathe; immersion promotes hydration and good shedding. Clean and renew the water regularly (the animal often defecates in it).

Central South America: Argentina, Paraguay and Bolivia, mainly in the semi-arid, wooded region of the Gran Chaco (formerly classified as Tupinambis rufescens).

Omnivore — Fruits (a very important part), lean meats and whole prey (rodents, chicks, fish), insects, eggs, snails; calcium/vitamin D3 supplements.

A balanced omnivorous diet in which fruits (figs, berries, melon, mango, banana in moderation) play a larger role than in most tegus. Alternate lean animal protein and plant matter; supplement with calcium (with D3 depending on UVB). A species very prone to OBESITY: strictly ration adults (2-3 meals/week), avoid excess fatty meat and rodents.

Clutch 10–30 eggs/young. Reproduction is triggered by a seasonal cycle including a winter hibernation/brumation period followed by warming. The female often builds a nest and may guard her clutch. Artificial incubation of about 50-65 days at ~28-30 °C. Notable fact: the neonates are green/brown and the characteristic reddish colouration intensifies with age.

• Shedding problems (dysecdysis) linked to too low humidity, which can cause retained shed on the toes and tail tip
• Obesity from overfeeding, very common in captive adults and a cause of hepatic steatosis
• Metabolic bone disease (MBD) from a deficiency in UVB, calcium or D3
• Respiratory infections (an environment too cold, too humid or poorly ventilated)
• Internal and external parasites, especially in wild-caught individuals
