Here's why:
* "Panther" is a general term: It doesn't refer to a specific species. It often describes black leopards or black jaguars.
* Melanin affects color: Melanistic animals (like black panthers) have a higher concentration of melanin, which influences their fur, but not necessarily their nose color.
* Nose color varies: Like humans, individual panthers can have different shades of nose color, from pink to brown to black.
So, it's impossible to say definitively what color a panther's nose is. Just like any other animal, there's a range of possibilities!
