They have round or oval pupils, which allows them to open as wide as possible at night, but close almost completely in bright light, which protects light-sensitive cells.Īlthough there is little research on mountain lion hearing, it is known that domestic cats have very acute hearing and can detect prey using both sight and sound. Mountain lions have extraordinary vision. Their preferred prey are deer and elk and they have co-evolved with deer and elk as their primary prey. Mountain lions also have retractable claws, which they use to climb trees and capture prey. As such, they have large canines and sharp, specialized carnassial teeth (molars) for shearing and tearing flesh. Mountain lions are obligate carnivores, meaning they only eat meat.

Mountain lions used to be found throughout the United States, but due to bounty hunts in the early 1900s and threats such as persecution, trophy hunting, poaching, retaliation in response to livestock depredation, kitten orphaning, poisoning and habitat loss and fragmentation, mountain lions are now only found in 15 western states, and the genetically isolated Florida panther remains in the East. While their longitudinal range has remained, their latitudinal range has shrunk by more than half. Solitary cats, mountain lions are highly adaptable to situations and environments, and this adaptability has enabled them to survive across much of their original range in the America's, despite severe habitat loss and active threats. They are the most wide-ranging cat species in the world and are found as far north as Canada and as far south as Chile. Mountain lions are known by many names, including cougar, puma, catamount, painter, panther, and many more.
