Pumas (Puma concolor) are large, secretive cats. They are also commonly known as cougars and mountain lions and are able to reach larger sizes than some other "big" cat individuals. Despite their large size, they are thought to be more closely related to smaller feline species. The seven subspecies of pumas all have similar characteristics but tend to vary in color and size. Pumas live in a variety of habitats, including desert scrub, chaparral, swamps, and forests, but they avoid agricultural areas, flatlands, and other habitats lacking a cover.
