There are 5 species of Chiroptera but they are not numerous and are only found sporadically. Predators include Vulpes vulpes (widespread) and Canis aureus, C.lupus and Felis lybica are rare. Sus scrofa was recorded between Shahrisabs and Chirakchi. Of Rodents, Spermophilus fulvus, Rhombomis opinus and Ellobius tancrei are widespread. Reptiles are represented by 28 species: Testudines – 1 species (Agrionemis horsfieldi), lizards – 16 species, with Cyrtopodion caspius, Trapelus sanguinolentus and Phrynocephalus interckapularis being common; Varanus griseus is more rare. There are 11 species of snakes with Natrix tessellata, Coluber karelini and Psammophis lineolatum being common. Amphibia are represented by Rana ridibunda and Bufo viridis.
