The desert antelope that survives by drinking nothing but the moisture in plants

Nature · Published 3 October 2026 Swipe more like this →

In short: The addax is a master of extreme survival, thriving in the Sahara where others perish. By excreting dry waste and tolerating massive fluctuations in body temperature, this rare antelope avoids the need for standing water. Once widespread, it now faces a precarious future, with fewer than 100 remaining in the wild.

The addax, or Addax nasomaculatus, is uniquely equipped for the harshest environments on Earth. Unlike other North African antelopes that only venture into the central Sahara after rainfall, the addax is a permanent resident of the desert's vast sand dunes. Its physical design is a masterclass in adaptation: broad hooves allow it to traverse soft sand efficiently, while its coat shifts from a heat-reflecting white in summer to a darker, insulating gray in winter.

Physiologically, the addax is built to conserve every drop of moisture. It extracts all necessary hydration from its diet of coarse grasses, acacias, and water-storing tubers. When temperatures soar, the animal avoids overheating by allowing its body temperature to rise by as much as 6 °C before it begins to pant. By excreting highly concentrated urine and dry feces, it minimizes water loss, allowing it to endure conditions that would be fatal to most other mammals.

Despite these remarkable traits, the species has been decimated by human activity. During the late 20th century, poaching from motorized vehicles pushed the addax to the brink of extinction. Today, the International Union for Conservation of Nature classifies the species as critically endangered. While small, isolated populations persist in Mauritania, Niger, and Chad, the primary hope for the addax lies in captive breeding programs. Conservationists are now working to reintroduce these animals into protected areas within their historical range, aiming to restore a creature that once roamed from the Atlantic to the Nile.
