The wolf is the largest extant species of mammals living today. In the past, it could be found all over the northern hemisphere being able to adapt successfully to the most different living conditions.
The Iberian wolf (Canis lupus signatus) is a subspecies of the gray wolf. It lives in northern Portugal and Spain.
Wolves are slender, powerfully built animals with a body length of approximately 1,5 m and a tail length of 0,8 m. Its weight varies usually between 30 and 50 kg., sometimes exceeding 70 kg.
The physical performances of wolves are at least impressive. In search of food they can travel
over 100 km in one night. The running speed of the wolf can excess 60km/hour. Its senses are
extraordinary. Its smell, hearing and seeing are very fine, so the wolf can hunt very well at night.
Alimentation and dentition are typical to a carnivore. Although it is omnivore in need, being able to survive only with fruits and other vegetables (eating even the bark of a tree), the wolf favors meat. It behaves both like a hunter and a scavenger.
The mating takes place between February-March. The male stays with the female to raise their pups together. Then, the wolves (together with the young ones too) gather in packs which can mix during severe winters. After a gestation of 62-63 days, the female wolf gives birth to 4-6 pups. The pups are blind for about two weeks and are breastfed for 6 weeks.
