White Antelope (Addax nasomaculatus)

The Addax (Addax nasomaculatus / مهاة أبو حراب), also known as the white antelope or screwhorn antelope, is a critically endangered desert-dwelling bovid traditionally native to the hyper-arid regions of the Sahara Desert. Characterized by its pale, heat-reflective coat, dark brown facial patch with a prominent white "X" across the nose, splayed hooves adapted for walking on soft sand, and long, spiraled horns, the Addax is exceptionally equipped to survive without free water by extracting moisture directly from desert vegetation.

Featured alongside Arabian desert species in the Al Areen Wildlife Park series, the stamp highlights the sanctuary's broader zoological mission as a protected breeding center for globally threatened arid-zone ungulates. The realistic illustration captures the heads and shoulders of a pair of Addax in profile against a desert landscape, emphasizing the intricate spiral curvature of their horns and promoting international awareness for endangered arid wildlife.
