The term "panther" is often used to describe several different animals, some of which are endangered and some which are not.
Here are some examples:
* Florida Panther: This subspecies of cougar is endangered.
* Black Panther: This is not a separate species, but rather a melanistic (black furred) color variant of various felids, including leopards, jaguars, and cougars. The conservation status of the species they belong to varies.
* Snow Leopard: This species is endangered.
* African Leopard: Some subspecies of African leopard are threatened or vulnerable.
Therefore, to answer your question accurately, I need to know which specific panther species you are asking about.
