There are several synonyms for the term "black panther." One option is "black jaguar," which refers to the same species but is found exclusively in the Americas. "Black leopard" is another synonym, commonly used in Africa and Asia where these animals are found. Both of these synonyms refer to the melanistic coloration that causes the normally spotted coat of the jaguar or leopard to appear black. Other synonyms might include "melanistic cat" or simply "black large cat" when referring to any of the big cats with this coloration, though these terms are less commonly used in scientific or professional contexts.
