Canada lynx
The Canada lynx (Lynx canadensis) or Canadian lynx is a North American mammal of the cat family, Felidae. With the recognised subspecies, it ranges across Canada and into Alaska as well as some parts of the northern United States.With a dense silvery-brown coat, ruffed face and tufted ears, the Canada lynx resembles the other species of the mid-sized Lynx genus. It is slightly larger than the bobcat, with which it shares parts of its range, and over twice the size of the domestic cat.
