In short: Known as the mountain sheep, the argali is a master of high-altitude survival. These massive animals navigate terrain up to 5,800 meters high, sporting corkscrew horns that can weigh over 20 kilograms. While they share a lineage with domestic sheep, their wild habits and rugged lifestyle set them apart.

The argali, or Ovis ammon, stands as the largest living wild sheep, with a range spanning from Uzbekistan to southern Siberia and across the Tibetan Plateau. These animals are uniquely adapted to extreme environments, thriving at elevations between 300 and 5,800 meters. Their physical appearance varies by region, with coat colors ranging from pale yellow to dark grey-brown, often featuring a salt-and-pepper pattern during summer months.

Sexual dimorphism is striking in this species. While ewes are significantly smaller, rams possess massive, corkscrew-shaped horns that can reach 190 centimeters in length and weigh up to 23 kilograms. These horns are not merely for display; they are vital tools for male competition. In contrast, female horns are much smaller, typically measuring less than 60 centimeters. The species is highly social, living in herds that can number up to 150 individuals, though they generally segregate by sex outside of the breeding season.

The argali's survival is linked to its ability to navigate challenging terrain. In protected areas, they prefer gentle slopes, but they retreat to jagged, precipitous canyons when facing pressure from predators, human hunting, or competition with domestic livestock. Their migration patterns are primarily driven by seasonal food availability, though factors like drought, fire, and biting insects also trigger movement. Interestingly, genetic analysis has revealed complex relationships between various argali subspecies and urial sheep, highlighting a deep evolutionary history that predates the domestication of modern sheep, which began at least 5000 bce.
