Black Panther
The black panther is not actually a separate species, but rather a color variation of the leopard (or occasionally, the jaguar).
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Carnivora
Family: Felidae
Subfamily: Pantherinae
Genus: Panthera
Species: P. pardus (black leopard), P. onca (black jaguar)
Common Names: Black Panther, Panther
Both jaguars and leopards are solitary hunters that are most active at night. The jaguar is the apex predator in its range in South and Central America, while the leopard shares its habitat with other large predators, including lions, cheetahs, hyenas, and African wild dogs in Africa, and bears and tigers in Asia.
Leopards often prey on small to medium-sized antelopes and other hoofed animals, while jaguars prefer to eat giant anteaters and capybaras, though both will eat a variety of other prey animals when available.
Depending on the region, leopards may mate all year round, or only during January and February. Pregnancy lasts for around 100 days, after which a litter of two to four cubs is typically born. The gestation period of a jaguar is similar. Both leopard and jaguar cubs are born with their eyes closed. Leopard cubs will open their eyes after about a week, while jaguar cubs will open their after about two weeks.
Black panthers are melanistic variations of leopards or jaguars, meaning that an overproduction of dark pigments has resulted in very dark or black fur. Despite the common conception that they are uniformly black, the distinctive rosettes and spot patterns of the leopard and jaguar are still visible against the dark fur of the black panther.
In the leopard, black panthers are the result of a recessive gene variant, while in the jaguar, they are the result of a dominant gene variant.
Both species are members of the big cat genus Panthera, and are large powerful felines with strong jaws, sharp teeth and sharp claws. Like all “big cats”, they are able to roar.
Both cats are similar in length, able to grow about 6 feetlong (not including the tail, which can add another three feet or so). However, the jaguar is much more solidly built, and can weigh over 300 pounds. Leopards, meanwhile, rarely weight over 200 pounds.
The black panther is often given cultural significance due to its unique and interesting coloration. In Rudyard Kipling’s collection of stories, The Jungle Book, and its subsequent film adaptations, the black panther Bagheera plays a central role. The black panther served as the namesake of the political organization of the same name. A black panther also serves as the mascot of the Carolina Panthers NFL football team.
A popular Marvel superhero seen in comic books and movies is named after the black panther, and wears a costume with ears and claws that resemble that of the animal.
The leopard is considered a “Vulnerable” species, while the jaguar is “near threatened”. The main threats to both are habitat loss and fragmentation due to deforestation. The range of both cats has significantly reduced over the years. They both also face danger from human poaching.
Black leopards are not common, and about 11% of leopards are thought to be black panthers. In Africa, they are even rarer, and in 2019 researchers were able to confirm the first sightings of black panthers in the continent in over 100 years.
Black jaguars are also rare, with estimates ranging from 6-11% of the total jaguar population.
