Gazella leptoceros (F. Cuvier, 1842).

This is the palest gazelle; pale yellowish on the back and the undersides are white with indistinct markings. It is from 100-110 cm long; height at the shoulder is from 65-72 cm. The horns are long and slender in the males, smaller and slimmer in the females. The hooves are slightly spread to ease the movement on soft sand. The Slender-horned Gazelle lives almost entirely in sandy desert areas and feeds on desert plants including spiny shrubs, leaves, and grasses; it rarely has access to water. It is active during cooler parts of the day and possibly at night. The gestation period is 156-169 days; normally a single calf is born. In the past, its main predators were Cheetahs and Jackals but today its worst enemy is the man, and it is an endangered species due to the excessive hunting.
