Rau quagga walk on Elandsfontein farm, in the Riebeeck Valley, on February 3, 2016, near Wellington, about 90 km from Cape Town. In a spectacular valley less than two hours' drive north of Cape Town, a small herd of animals provides the chance to travel back in time over more than a century. The animals roaming over a wide plain encased by jagged mountain ranges look like quaggas, a subspecies of the plains zebra – but quaggas are extinct. A small group of scientists and conservationists believe they have recreated the quagga, which is distinct from other zebra mainly through the lack of the characteristic black and white stripes on its hindquarters.

This handout photograph taken on February 6, 2016 and released courtesy of Patrick Lees on February 12, 2016, shows a dead brown snake strung up on a spider's web with a “daddy long legs” spider by its tail in Weethalle, about 400 kilometres (250 miles) west of Sydney. A spindly spider has taken on a deadly brown snake – and won – in a very Australian telling of the story of David and Goliath. Lees' photo of the snake, strung up by its tail by spiders' webs and with the daddy long legs perched on it, has struck a chord since since he posted it to The Aussie Farmer Facebook page.
