For those interested: Black Panther is a name commonly given to big cats that are a melanistic variant of their species. Melanism is the over-development of black-coloured pigmentation in the skin; the opposite of melanism is albinism; an Albino or White Panther would be the result of this lack of black-coloured pigmentation.
The Black or Melanistic Panthers one is most likely to see in captivity are either Leopards from Asia or Africa, or Jaguars from South America. The subject you see here is an Asian Black Leopard. Even though their coats are predominantly black, in certain light the Leopard's (or Jaguar's) spots can still be seen showing through to varying degrees with each individual, which you can actually see a better example of in the previous picture I posted up than you can in this one ;^)
