Steve Backshall takes us to South Africa’s Ndumo Game Reserve to explore the dangerous world of hippos and crocs. Remarkable moments include the tagging of a formidable three-meter-long crocodile; the unique dietary habits of hippos (and how they cause conflict with local farmers) and how vulnerable these creatures are to climate change. Mixing cutting-edge technology to capture underwater footage – including thermal drones and pole-cams – with insights from expert scientists and local rangers, Steve uncovers a rarely-seen world.
