Crocodile

In this new series, vet Mark Evans uses technology to tackle three deadly predators: the Nile crocodile, the polar bear and the great white shark. When these animals attack humans both sides lose out. As more people are killed or maimed, more animals are killed in retaliation. Mark wants to find ways to break this circle of violence. He tries out ingenious solutions to the most hostile wildlife conflicts on Earth. Mark travels to Namibia's Chobe River, which is known as the crocodile attack capital of the world, and finds himself in serious danger when a ferocious attack leaves him badly wounded. Crocodiles here are growing in size and number, and so is the frequency of attacks. Each time it happens, the locals kill crocodiles in retaliation. To find a way to keep both people and crocodiles safe, Mark carries out a radical new experiment with leading crocodile experts Rom Whitaker and Dr Patrick Aust. The idea is to train crocodiles to associate the sound of a bell with an electric shock. Mark meets attack victims, puts the crocodile training experiment to the test and is himself injured when a crocodile turns on him.
