A few months ago when we spoke to science writer Leonie Joubert about getting published in National Geographic for the first time, she mentioned that her piece on the Kalahari would never have made it to print without the magnificent work of the photographer Thomas Peschak. He’s probably best known for his famous photo of a great white shark trailing behind a kayaker off the South African coastline – the image has been used in memes and fake news posting ever since. But it’s just one of the hundreds of thousands of staggering wildlife photographs which Thomas has taken over the course of his career. Now he has put together a collection of around 200 of his favourite images which have been released in a gorgeous hardcover book called Wild Seas.
