The dhub, scientific name Uromastyx aegyptius microlepis, is a large diurnal lizard that can grow to a length of over a metre. Its natural habitat is arid sandy areas with soft sedimentary stone outcrops in which it utilises holes as burrows, for breeding and for shelter. It is largely absent from areas of high dunes but is occasionally found on inter-dunal plains, although not on inland sabkha (salt-flats) . It is the largest of the United Arab Emirate's reptiles, its diet is completely herbivorous. Unfortunately it appears quite often as a casualty on the roads, numbers are declining in some areas as a result of development although populations in remoter areas seen secure. Officially protected, some are killed for their tails, which are a traditional local delicacy.
