Wonder Gecko
Teratoscincus scincus
Native to Central Asian deserts, this nocturnal terrestrial gecko has incredibly fragile, fish-like scales. It requires a horizontal enclosure of 80x40x40 cm with deep, fine sand for burrowing and must not be handled frequently.

Species description
Geographical Origin and Habitat: Native to the desert regions of Central Asia (from Iran to western China). Inhabits sandy dunes and arid desert plains, digging deep burrows in the ground. They inhabit environments with extreme daily temperature fluctuations, adapting to high thermal ranges. Their natural burrows can reach depths of nearly a meter to find moisture.
Taxonomy and Genetics: Family Sphaerodactylidae, genus Teratoscincus. Evolutionarily adapted to extreme desert climates with high temperature fluctuations. Their unique scales have evolved to minimize water loss in hyper-arid environments. Recent genetic research indicates a high level of divergence among desert populations.
Behavior and Habits: Strictly nocturnal and terrestrial. An expert burrower. When threatened, they produce a rattling sound by rubbing their large tail scales together. They exhibit a unique defensive posture, raising their body high on their legs to appear larger. Stridulation is achieved by vibrating the tail, producing a dry, rustling hiss.
Morphology: Reaches 15-20 cm (6-8 inches) in length. Characterized by large, prominent eyes and wide, flat, overlapping dorsal scales resembling fish scales. Their large eyes possess specialized pupils designed for acute nocturnal vision in low-light deserts. The scales are so fragile that they easily tear off during aggressive contact.
Care, breeding and tankmates
Terrarium Setup: Horizontal desert enclosure (minimum 80x40x40 cm). A deep substrate of fine sand (at least 15 cm / 6 inches) is essential, with the bottom layer kept damp to allow stable burrowing. Ensure all heavy decor items are secured to prevent them from collapsing when the gecko burrows. Provide multiple pre-made clay or plastic hideaways to prevent collapse.
Lighting and Heating: Provide a warm spot of 32-35°C (90-95°F), a cool zone of 24-26°C (75-79°F), and a night drop to 20°C (68°F). Low-level (5%) UVB is recommended. Do not use heating mats under the tank as geckos burrow to escape heat, which could lead to burns. A ceramic heat emitter is preferred for night heating.
Humidity and Hydration: Low ambient humidity (30-40%). Mist the lower layers of the sand substrate to recreate the natural subterranean humidity of their burrows. Ensure the cool side burrow remains moist, while the surface sand is kept dry. Monitor the humidity inside the hide regularly using a probe sensor.
Feeding and Supplementation: Insectivorous. Feed appropriately sized crickets, roaches, and locusts. Dust prey with calcium and Vitamin D3 twice a week. Feed them in a shallow bowl to minimize the risk of accidental sand ingestion during feeding. Feeder insects should be gutloaded with nutritious greens.
Compatibility: Males are territorial and must not be housed together. Handling should be strictly avoided: their skin is incredibly thin and fragile and tears easily as a defense mechanism. They are solitary animals that do not benefit from social interaction, so individual housing is best. Males will engage in violent combat if housed together.
Health and Common Diseases: Major issues include skin tears from improper handling, intestinal impaction from substrate ingestion due to calcium deficiency, and dehydration if burrow humidity is neglected. Watch for retained shed on the toes, which can restrict blood flow and lead to necrosis. Avoid handling unless absolutely necessary to prevent severe skin damage.

The catalog's scalar value is 12 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 12 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.
