Diamond is a Black Leopard. also commonly known as the Black PantherThe jaguar is the largest cat indigenous to North, Central and South America. The black jaguar (also known as "panther") results from a dominant gene mutation that produces excess melanin and a mainly black coat. Black jaguars, about 6 percent of the entire jaguar population, are found in the densest part of the vegetation, where there is the least sunlight. the most common predator and biggest threat to all Panthers is people. Not only have these rare animalsbeen hunted by people throughout much of their natural range but they have also been subjected to drastic habitat loss particularly in the form of deforestation for both growing Human settlements and to make way for agriculture. Population numbers of large Cats are declining all around the world and when they are being pushed into smaller and smaller pockets of their native habitats, Panthers are becoming even rarer than they already were.
