The largest uromastyx species (24-30in) and the most humidity-sensitive in the whole genus — aim for only 10-30%, notably drier than the other uromastyx on this list. Needs the largest enclosure, worth planning for before purchase given its imposing adult size.

Common questions

Why does it need less humidity than other uromastyx?
It's the most humidity-sensitive in the whole genus — aim for only 10-30%, versus 20-25% for the other species on this list. Excess humidity causes real respiratory issues specifically in this species.
How big does it actually get?
24-30 inches long as an adult — the largest species in the genus, notably more imposing than the "niger" or Mali. Plan for the adult enclosure from the start rather than being surprised down the line.
Do I really need to feed it insects?
No — an almost strict herbivore like the other uromastyx.
