Isn't a "panther" technically like a misidentified cougar or leopard. I saw on discovery channel one time that a Panther is really just the black version of several species of animals.
Maybe we should be the Carolina Misidentified Cougars.
"Panthera" includes tigers, leopards, jaguars, etc.
In North America, the "panther" is a cougar or mountain lion. You can call it any of those. Yes, the Carolinas have panthers (cougars, mountain lions).
