Definition
Meaning
A small, diurnal lizard of the genus Uma, found in arid desert regions of North America, characterized by specialized scales on its toes that aid in running across loose sand.
Refers specifically to several species within the genus Uma, known for their adaptations to desert life, including the ability to 'swim' beneath the sand's surface to escape heat and predators. The term highlights a unique physical trait as the primary identifier.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid a literal translation like 'ящерица с бахромой на пальцах' which sounds odd. The established zoological term is 'песчаная игуана' (sand iguana) for the genus Uma, though not a true iguana. 'Ящерица с бахромчатыми пальцами' is a more accurate descriptive term.
Common Mistakes
- Misspelling as 'fringed-toed lizard'. The standard form is 'fringe-toed'.
- Confusing it with the unrelated 'horned lizard' or 'beaded lizard'.
- Using it as a general term for any lizard in the sand.

FAQ
Frequently Asked Questions
No. They are small, insectivorous lizards and pose no danger. They are shy and will retreat or bury themselves in the sand if threatened.
It is generally not recommended and is often illegal. Many species are protected due to habitat loss and require very specific, difficult-to-replicate desert sand dune conditions to thrive.
In the wild, only in specific desert dune habitats in the southwestern United States and northwestern Mexico, such as the Coachella Valley in California. They may also be seen in some specialised zoos or conservation centres.
It has adaptations like valved nostrils and special breathing methods to prevent sand inhalation while submerged just below the surface.
