Anatomy and Morphology
An Arabian oryx stands about 1 m (39 in) high at the shoulder and weighs around 70 kg (150 lb). Its coat is an almost luminous white, the undersides and legs are brown, and black stripes occur where the head meet the neck, on the forehead, on the nose and going from the horn down across the eye to the mouth. Both sexes have long, straight or slightly curved, ringed horns which are 50 to 75 cm (20 to 30 in) long.
Arabian oryx rest during the heat of the day and can detect rainfall and will move towards it, meaning they have huge ranges; a herd in Oman can range over 3,000 km2 (1,200 sq mi). Herds are of mixed sex and usually contain between two and 15 animals, though herds of up to 100 have been reported. Arabian oryx are generally not aggressive toward one another, which allows herds to exist peacefully for some time.
Other than humans, wolves are the Arabian oryx's only predator. In captivity and good conditions in the wild, oryx have a life span of up to 20 years. In periods of drought, though, their life expectancy may be significantly reduced by malnutrition and dehydration. Other causes of death include fights between males, snakebites, disease, and drowning during floods.

“Man is a shrewd inventor, and is ever taking the hint of a new machine from his own structure, adapting some secret of his own anatomy in iron, wood, and leather, to some required function in the work of the world.”
—Ralph Waldo Emerson (1803–1882)
“I ascribe a basic importance to the phenomenon of language.... To speak means to be in a position to use a certain syntax, to grasp the morphology of this or that language, but it means above all to assume a culture, to support the weight of a civilization.”
