"This is a black female Jaguar that I captured at the amazing WHF in Kent. The Jaguar is the largest feline on the American continent, and is the only one of the world's 'big' cats to be found in the New World." AKA a panther.
A BLACK LEOPARD --notice you can see the leopard markings. A "black panther" is not its own species—it's an umbrella term that refers to any big cat with a black coat. Cats called Black Panthers have spots too, they are just harder to see.
