Panthers live in the western United States, Florida, western Canada and southern South America. Panthers can be found in deserts, prairies, swamps and forests. They are known by several other names, such as cougar, puma and mountain lion, depending on the region, but are primarily called pumas by scientists.
Panthers are a tawny color, with a white underside and darker hair on the back. Those living in warmer areas tend to be a darker reddish brown while those in colder areas are almost silver-gray. Males tend to weigh up to 60 percent more than the females. Panthers have large paws with sharp claws, which they use to kill prey. They mainly hunt during dawn and dusk, using their sharp eyesight to spot prey moving in their area.
