Black Panther
A black panther is the melanistic colour variant of the leopard and the jaguar. Black panthers of both species have excess black pigments, but their typical rosettes are also present. They have been documented mostly in tropical forests, with black leopards in Kenya, India, Sri Lanka, Nepal, Thailand, Peninsular Malaysia and Java, and black jaguars of the Americas in Mexico, Panama, Costa Rica, Brazil and Paraguay. Melanism is caused by a recessive allele in the leopard, and by a dominant allele in the jaguar.
