Uromastyx thomasi
A small mastigure of coastal Oman and Kuwait, about 26 cm in total length. The specific name honours Bertram Thomas, a civil servant who served in Mesopotamia during the First World War.
Uromastyx thomasi occurs in coastal Oman and in Kuwait and is one of the smaller mastigures, about 26 cm in total length. Like others in the genus it has a thick, flattened body, a large head, a short snout and rings of spiny scales along the tail. The specific name honours Bertram Thomas (1892-1950), a civil servant who served in Belgium and then in Mesopotamia during the First World War. It does not occur in Yemen, and records from Bahrain and Saudi Arabia are regarded as doubtful. Terrestrial and diurnal, it lives in desert and stony wasteland, digs deep burrows and retreats into them at night. It is herbivorous, eating leaves, flowers, fruit and seeds, and it may show temperature-dependent sex determination.

Uromastyx spp. has been listed under Washington Convention Appendix II, effective February 4, 1977. Because it is listed under Appendix II, no registration certificate as an internationally rare wild animal or plant species is required. It is neither listed as a specified animal under the Ordinance for the Enforcement of the Act on the Welfare and Management of Animals, nor designated as a specified alien species. In its native habitat, it is consumed as food, with the meat of its thick tail considered particularly delicious.

Leafy greens, wild plants such as dandelion and clover, birdseed and prepared herbivorous-lizard diets
The basking surface must be very hot, 49-55 C, with the cool side around 29 C. Because the heat source is localised, use an enclosure large enough that the whole cage does not overheat. Its UV requirement is high, so fit a strong UVB lamp, and let the temperature fall a little at night.
Keep humidity very low, at 20-30 per cent. Suitable substrates include reptile sand, ground corn cob and akadama soil. It digs deep burrows in the wild, so a deep substrate is preferable; where that is impractical, provide hides of brick, rock or flowerpot.
Herbivorous: build the diet on leafy greens such as komatsuna and on wild plants like dandelion and clover. Birdseed, prepared tortoise or herbivorous-lizard diets and vegetables such as carrot and squash can be added. It need not be fed every day.
A threatened animal lashes its tail, hisses with a rasping call and bolts for a burrow. Captive animals also swing the tail when touched, and the spines hurt. Many adults spend most of the day resting.
The genus Uromastyx has been on CITES Appendix II since 4 February 1977. Appendix II species need no individual registration certificate in Japan, and the lizard is neither a designated dangerous animal nor an invasive alien species. It is eaten within its range, where the meat of the thick tail is especially prized.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
