The global wild wolf population was estimated to be 300,000 in 2003 and is considered to be of A 2016 genomic study suggests that Old World and New World wolves split around 12,500 years ago followed by the The common ancestor of the coyote and the wolf has admixed with a Adult wolves measure 105–160 cm (41–63 in) in length and 80–85 cm (31–33 in) at shoulder height.The wolf has very dense and fluffy winter fur, with a short In cold climates, the wolf can reduce the flow of blood near its skin to conserve body heat. This pair is monogamous although, with the death of an alpha individual, a new alpha male or female will emerge and take over as the mate.Breeding occurs between the months of January and April, with northern populations breeding later in the season than southern populations. These follow the banks of rivers, the shorelines of lakes, through ravines overgrown with shrubs, through plantations, or roads and human paths.The wolf usually travels at a loping pace, placing one of its paws directly in front of the other. Pups are born in the den and will remain there for several weeks after birth.
A wolf can consume up to 9 kg of meat at one meal. Until they are 45 days old the pups are fed regurgitated food by all pack members. Pups are cared for by all members of the pack. Each pack comprises two to thirty-six individuals, depending upon habitat and abundance of prey.

As well as causing economic losses, the threat of wolf predation causes great stress on livestock producers, and no foolproof solution of preventing such attacks short of exterminating wolves has been found.The majority of losses occur during the summer grazing period, untended livestock in remote pastures being the most vulnerable to wolf predation.A review of the studies on the competitive effects of dogs on Wolves kill dogs on occasion, and some wolf populations rely on dogs as an important food source.

Wolves usually utilize the entire carcass, including some hair and bones. Ecotourism implies that there are existing programs that profit from the appreciation of natural areas or animals.animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Wolves may attack coyote den sites, digging out and killing their pups, though rarely eating them. Five to ten days later, the young are able to stand, walk, and vocalize.
