The Interior Alaskan Wolf
They are distributed throughout the interior of Alaska and the Yukon, except the tundra region of the arctic coast.
Interior Alaskan Wolves are usually of a darker color, most often black or black mixed with either brown, gray, or white. They are very large wolves, measuring 5 to 7 feet in length from tip of nose to end of tail. They are at present the largest wolves in North America and possible the world.
Some of what they feed on are caribou, moose, dall sheep, hares, and ground squirrel.
