Giant sable antelope
The giant sable antelope, also known in Portuguese as the palanca negra gigante, is a large, rare subspecies of the sable antelope native and endemic to the central highlands of Angola, occurring specifically in two areas: Cangandala National Park and Luando Natural Strict Reserve.
It was first described in 1916 by Frank Varian, a British engineer and naturalist, as a new subspecies of sable antelope distinguished by its size, horn structure and length, and unique facial markings. At the time, Varian worked on the construction of Angola's Benguela Railway, which connected the inland mining areas with the Atlantic coast. His work in the remote highlands brought him into contact with some of the country's unique wildlife, leading to his discovery of the giant sable, which he subsequently documented and brought to scientific attention. The giant sable was the last of the large antelopes to be discovered, with its discovery occurring after that of the Okapi.
There was a great degree of uncertainty regarding the number of animals that survived during the Angolan Civil War. In January 2004, a group from the Centro de Estudos e Investigação Científica of the Catholic University of Angola, led by Dr. Pedro Vaz Pinto, was able to obtain photographic evidence of one of the remaining herds from a series of trap cameras installed in the Cangandala National Park, south of Malanje.
The giant sable antelope is the national symbol of Angola, and is held in a great regard by its people. This was perhaps one of the reasons the animals survived the long civil war. In African mythology, just like other antelopes, they symbolize vivacity, velocity, beauty and visual sharpness.
The giant sable antelope is evaluated as critically endangered on the IUCN Red List of Threatened Species. As of 2021 they reportedly only have a population of 300, 100 of which are living in Cangandala National Park.
Description
Both sexes have horns, which for the male can reach 65 inches. Males and females are very similar in appearance until they reach three years of age, when the males become darker and develop majestic horns. The males weigh an average of with a height of. Females weigh 220 kg and are slightly shorter than males. The horns are massive and more curved in males, reaching lengths of, while females' horns are only in length. Coloration in bulls is black, while cows and calves are chestnut, except in southern populations where females turn brownish-black. Most sable antelopes have white "eyebrows", their rostra are sectioned into cheek stripes, and their bellies and rump patches are white. Young under two months old typically are light brown and have slight markings.The largest giant sable antelope horns recorded to date measured 65 inches long. The animal was shot by the Count of Yebes in Angola in 1949 and became the world record.
Ecology and behavior
Like all antelopes, giant sables are shy by nature, but they can also be very aggressive. The males can be especially dangerous when hurt, attacked, or approached. In fights, males avoid some serious injuries by kneeling down on their front legs, and engage in horn-wrestling fights. Fatalities from these fights are rare.Juveniles are hunted by leopards and hyenas, while adults are only threatened by lions and crocodiles. When startled, the antelope normally runs for only a short distance before slowing and looking back; however, when they are pursued, they can run at speeds up to 35 mph for a considerable distance.
