If a leopard or jaguar is black what it often called?

A black leopard or jaguar is often called a melanistic leopard or jaguar. This is because the animal has an excess of melanin pigment, which causes its coat to be black.

While the terms "black panther" and "black jaguar" are often used, it's important to note that they are not distinct species. They are simply melanistic versions of the leopard and jaguar, respectively.
