The wolf is a carnivore with a rigorous hierarchy within the pack and very territorial. It is a medium-sized animal, about 130 cm long and weighing up to 70 kg. The neck muscles are very developed, which helps him to carry prey, but it is just a popular belief that he could not turn his head. The fur is reddish-gray in summer and light gray in winter, closer to the white of the snow so that it can be seen by prey. Smell, hearing and sight are very developed.The hierarchy of the pack of wolves causes the pair that participates in reproduction to inhibit the mating instinct of the other members of the group. The wolf has only one partner all his life and the male takes care of the food. A female girl around 7 chicks, but sometimes up to 13. The den is arranged in galleries with several exits, in burrows of fox.
