The Snow Koryak Sheep, also known as the Putorana Snow Sheep, is a remarkable species adapted to survive in the harsh, snowy environments of the Putorana Plateau in Koryak, Russia. They have a thick double-layered coat to withstand extreme cold. The outer layer consists of long, coarse guard hairs that protect the inner layer of soft, dense wool. This insulation keeps them warm and allows them to survive in temperatures as low as -50°C (-58°F).

These sheep inhabit the Putorana Plateau, a remote region with challenging weather conditions. The plateau is covered with snow for most of the year, making it essential for the sheep to adapt to this environment. Snow Koryak Sheep are social animals that live in herds. Their herd structure provides protection against predators and helps them find food and shelter together. The herds can range in size from a few individuals to hundreds. To find food and avoid the worst of the winter weather, these sheep undergo seasonal migrations. They move between lower valleys in winter and higher mountainous regions in summer. This migration pattern helps them survive in a changing environment.

As herbivores, Snow Koryak Sheep feed on grasses, shrubs, and lichens. During the short summer season, they graze in alpine meadows, taking advantage of the brief period when vegetation grows.

Snow Koryak Sheep face several predators in their habitat, including wolves, lynxes, and eagles. Their keen senses of sight, smell, and hearing help them detect danger and respond swiftly to threats. 

These sheep have cultural importance to the indigenous Koryak people. Their wool is used to make warm clothing and traditional crafts, reflecting the deep connection between the people and the animals that share their homeland.

Due to the remoteness of their habitat and limited human interference, Snow Koryak Sheep populations have generally remained stable. However, it's important to protect their environment to ensure their continued survival.
