Wolves are large, predatory canids once common throughout North America, Europe, Africa and Asia, now living mostly in remote wilderness.
They are the largest living members of the canid family, which also includes foxes and coyotes. Wolves are the ancestors of all domestic dogs.
Wolves live in all kinds of terrain, from desert to tundra. They prefer areas with cover (places to hide such as brush, shrubs, or trees), near water, and near large congregations of prey (herds of deer or caribou, for example).
Wolves primarily eat meat. Wolves will eat non-meat items (such as vegetables), but not often.
As of 2013, there are four species of wolves in the world: the gray wolf (Canis lupus), the red wolf (Canis rufus), Eastern wolf (Canis lycaon) and the Ethiopian wolf (Canis simensis).
