scimitar oryx was a very sociable animal and traveled in herds of two to 40 individuals, generally, led by a dominant bull. This species once gathered in groups of several thousand for migration. During the wet season, they migrated north into the Sahara. Scimitar oryx are diurnal. In the cool early mornings and evenings, they rest under trees and shrubs, or if neither is available, they dig depressions in the soil with their hooves and rest there. Males fight often, but not for long and not violently. Predators, such as lions, leopards, hyenas, cheetahs, golden jackals, vultures, and Cape hunting dogs, mostly kill weak and young oryx. Adaptations With a metabolism that functions at the high temperatures prevalent in their habitats, scimitar oryxes need less water for evaporation to help conduct heat away from the body, enabling them to go for long periods without water. They can allow their body temperatures to rise to almost before beginning to perspire. In times of ample supply, oryx can use fluid loss through urination and feces to lower their body temperatures to below at night, giving more time before reaching maximum body temperature the following day. They can tolerate high temperatures that would be lethal to most mammals. They have a network of fine blood vessels that carries blood from the heart to the brain, passing close to the nasal passage, thus allowing the blood to cool by up to before reaching the brain, which is one of the more heat-sensitive organs of the body. Diet The habitat of the scimitar oryx in the wild was steppe and desert, where they ate foliage, grass, herbs, shrubs, succulent plants, legumes, juicy roots, buds, and fruit. They can survive without water for 9-10 months because their kidneys prevent water loss from urination – an adaptation to desert habitats. They can get water from water-rich plants such as the wild melon (Citrullus colocynthis) and Indigofera oblongifolia and from the leafless twigs of Capparis decidua. In the night or early morning, they often search for plants such as Indigofera colutea, which produce a hygroscopic secretion that fulfills water requirements. They eat tuft grasses such as Cymbopogon schoenanthus after rains, but they normally prefer more palatable grasses, such as Cenchrus biflorus, Panicum laetum, and Dactyloctenium aegyptium. When the dry season begins, they feed on the seedpods of Acacia raddiana, and during the dry season, they rely on perennial
