When playing or alarmed, gazelles' exhibit stotting or pronking,gaits,bounding along stiff-legged with all four limbs landing together. Both males and females possess horns, possibly evolved in response to each having to defend its own food resources. Little is known about mhorr gazelle courtship or breeding habits in the wild, as there are now none left to observe. However, all gazelle males establish territories during the breeding season, and actively exclude other mature males while females are receptive. Gestation period is about seven months and young are born singly.
Newborns lie outside the herd, hidden in foliage for the first few weeks after birth.
Mothers come to nurse, calling the infant with soft bleating. Mhorr gazelles are extinct in the wild. In 1971, the World Wildlife Fund established a private game reserve in Almera, Spain. German zoos in Frankfurt and East Berlin, and the San Diego Zoo in California each received small herds for further captive breeding. The Living Desert has a breeding pair on loan from San Diego.
