A black panther is typically a melanistic color variant of any of several species of larger cat. Wild black panthers in Latin America are black jaguars (Panthera onca), in Asia and Africa they are black leopards (Panthera pardus), and in North America they may be black jaguars or possibly black cougars (Puma concolor – although this has not been proven to have a black variant), or smaller cats.
