Panthera tigris altaica
Siberian tigers are the largest cats in the world, and among the most beautiful mammals. Unfortunately, they are at the verge of extinction, with only around 500 individuals remaining free in their natural habitat.
Siberian tigers can be distinguished from the other kinds of tigers because of their longer hair, sparser and brownish (rather than black) stripes, and their color which becomes lighter (yellowish, sometimes almost white, as in the above picture) in the winter. That picture was taken at the Cincinnati zoo, in February 2005.
One more beauty below, this one from Chicago zoo, in May 2000.
