Snow Kolyma sheep, also known as Russian Snow Sheep or Putorana Snow Sheep, are intriguing animals found in the cold and remote regions of Siberia. They are large, robust creatures with a body covered in dense, wooly fur. Their wool can be white or light gray, providing excellent camouflage in snowy landscapes. They have a distinctive pair of curved horns, which are more prominent in males (rams) than females (ewes).

These sheep inhabit the rugged terrain of the Putorana Plateau and Kolyma Mountains in Siberia. Their habitat is characterized by freezing temperatures, icy winds, and snowy conditions for a significant part of the year. To survive in their harsh environment, Snow Kolyma sheep have developed several adaptations. Their thick wooly coat acts as insulation against extreme cold, and they also have a layer of fat under their skin that helps them conserve body heat. Additionally, their hooves are specially adapted to grip icy and rocky surfaces, allowing them to navigate treacherous terrains with ease.

Snow Kolyma sheep are social animals that form flocks. Within the flock, there is a hierarchy, with dominant individuals leading and others following. They communicate with each other using various vocalizations and body postures.

Snow Kolyma sheep are herbivores with a diverse diet. In their natural habitat, they graze on grasses, sedges, mosses, and other alpine plants, which maintains a balanced ecosystem. They have an efficient digestive system that allows them to extract nutrients from tough vegetation found in their cold environment. 

These sheep face threats from predators such as wolves, snow leopards, and bears. Their excellent camouflage and group living behavior provide some protection, but they still need to be vigilant to survive. Due to their limited range and the challenges of living in extreme environments, Snow Kolyma sheep are considered a vulnerable species. Conservation efforts aim to protect their population and preserve their natural habitat.
