Beisa oryx has a number of physiological adaptations which allow it to conserve water. Under conditions of extreme heat and low water, the oryx can raise its body temperature to 46.5 C up to this temperature. This species has long horn, the female horn are longer and more slender and the male is heavier than the female. The horns are long narrow and virtually parallel, ridged on the lower half. This animals have a gray coat with white underside, separated from the gray by a stripe of black, there are also black stripes where the head attaches to the neck, along the nose and from the eye to the mouth and on the forehead. This species looks a little bit weird. They look like a cow but also look like a goat. This Beisa oryx live in semi-desert and stepped where they eat grass, leaves, fruit and buds. They are able to store water by raising their body temperature. As for breeding season, occurs through the year, though synchronized calving have been reported. After birth, calves lie up for 2-6 weeks, after which they join the herd. There is no recent confirmation of beisa oryx occurrence in Eritrea, where its status is uncertain. Likewise, the failure to locate any oryx during a 1995 aerial survey of Bokora Corridor, Matheniko and adjoining areas of Karamoja suggests that it has either disappeared completely from Uganda or at best survives in very small numbers. It is native to Ethiopia, Kenya, Somalia, Sudan, Tanzania etc.
