Postprandial thermophily (PT) is an increase of preferred body temperature following food consumption. PT helps to maximize digestive functions. We compared the preferred body temperature after feeding in a species Uromastyx acanthinurus. We tested ten individuals and repeated each experiment twice. Our results clearly demonstrate the occurrence of postprandial thermophily in Uromastyx acanthinurus. The average temperature raised 3,82°C after feeding. We found the marginal significance of the relationship between temperature before and after feeding and the length of the individual.
