The cougar (Puma concolor), also known as puma, mountain lion, or panther, depending on region, is a mammal of the Felidae
family, native to the Americas. This large, solitary cat has the greatest range of any wild terrestrial mammal in the Western Hemisphere, extending from Yukon in Canada to the southern Andes of South America. An adaptable, generalist species, the cougar is found in every major American habitat type. It is the second heaviest cat in the American continents after the jaguar, and the fourth heaviest in the world, along with the leopard, after the tiger, lion, and jaguar, although it is most closely related to smaller felines.
