The disappearance of the giant sable: The giant sable antelope was first discovered in the early 20th century and went on to become Angola’s national animal. However, due to their striking horns, the antelopes soon became a target for poachers, says renowned Angolan conservationist Pedro Vaz Pinto. In 1975, their prospects took a turn for the worse when a civil war broke out in Angola following its independence from Portugal. Over the next 27 years, the conflict devastated the country's wildlife and the giant sable was no exception.
