Wolves are one of the wild nature’s most perfect creatures. The shape of the animal itself speaks for its power and excellent fitness for unresting running, drive and attacking its prey. An adult wolf is bigger than a sheepdog. Its body length is 105-160 cm, the height at the shoulder is 80-100 cm. The average weight is 50-70 kilos. There are reports of wolves weighing more than 90 kg. These grey predators have very sensitive nose, acute hearing and sight as well as tireless legs. During the hunt they can reach the speed of 65 km/h making jumps of 5 meters long. An important characteristic that helps the animals to survive in severe winter conditions is their fur’s low thermal conductivity (1.2-1.5 lower than thermal conductivity of beaver’s or muskrat’s fur).

The wolves populate almost all the northern hemisphere preferring steppes, semi-deserts, tundra, forest-steppes and avoiding thick forest areas. They can settle near places of human inhabitation. The most common food is hoofed animals: deers, elks, roe-deers and boars. The wolves frequently attack domestic animals: sheep, cows and horses; they often kill dogs. The time of maximum activity is night hours. After thousands of years of wild life the body of the wolf has become so perfect that it is not subject to any diseases.

There are two subspecies living in Siberia: tundra wolf (populates tundra and forest-tundra) and Siberian forest wolf (taiga). The first one is less in size and has light color. The latter is bigger, light-grey with darker back and without orchry tones. There is also a medium-sized gingery-colored wolf inhabiting in the south of the Krasnoyarsk Territory.
The breeding time is in January-February (the south of the Krasnoyarsk Territory) and in March (the Taimyr Peninsula). The gestation lasts for 63-65 days. In the northern regions the cubs are born in the late May-early June. The lairs are arranged in burrows, rock-splits and caves. There are 5-7 cubs in a brood (up to 11 cubs in Taimyr region). The life of wolves in the North is closely connected with reindeers herds – wolves and reindeers migrate together. In Taimyr the wolves live settled only 3 months a year (May-July); in winter the animals leave the tundra.
