Many Native American and Inuit tribes revere the wolf as a brother and fellow hunter. They have great respect for the wolf and will never speak badly about it.
In 1926, the last wolf was killed in Yellowstone National Park. A wolf reintroduction program was implemented in 1995. The program is considered to be a great success – the wolves are reproducing at a rapid rate, and there are currently around 100 wolves in the park.
Adult gray wolves have 42 teeth, compared to 32 teeth for adult humans
After a successful kill a wolf may eat 20 pounds of meat at one go because it never knows when it will get a good meal again.
