The wolf is included in the category of the oldest species
The gray wolf is one of the oldest species on earth – has more than 100,000 years living in this world. I used to live in most of the northern hemisphere, apart from humans, the wolf has been the most widespread mammal in the world throughout history. In fact, wolves live in almost all parts of the world except in tropical rain forests and deserts.
The wolf lives of 6 to 12 years within an established territory that “belongs” to its pack, and which usually includes 150 to 300 km2. Mark their territory as they stroll through glands in the foot that emit an odor, and urine. The wolf has a blood vessel in his legs that control their body temperature and prevents the formation of ice balls between their feet, even during the winter.
Wolves are very social animals. Live, travel and hunt in highly organized groups, usually 6 to 12 animals. Each group has a male partner whose dominant male dominates the female to other females. The dominant pair are often the only group to have puppies. About three weeks before giving birth, the female digs a tunnel in the earth creating a shelter. Once you give birth to their young, it stays there with them until they are 8 to 10 weeks. The female must choose carefully where to make the refuge, a place where other wolves in the group can hunt and defend without problem, and is near a water source.
The Wolves take only milk for a month and then pre-engineered food eaten by other group members. Sometimes puppies are raised a paw to ask for food. When puppies are still very small, some are wolves of the pack of “babysitter” to care for the young when the mother goes to drink water, exercise or do their business.
Wolves have several ways to communicate through howling, growling, barking, smell and body language. Use their tail to convey strength, submission, aggression and fear. Wolves used their howls to announce their presence and warn intruders. Group members also howl to locate each other when they are away. Some people even believe that wolves howl made his famous just for fun.
