Dung beetles that steer by the light of the Milky Way. Ants and bees that navigate using patterns of light invisible to humans. Sea turtles, spiny lobsters and moths that find their way using the Earth's magnetic field. Salmon that return to their birthplace by following their noses. Baleen whales that swim thousands of miles while holding a rock-steady course and birds that can locate their nests on a tiny island after crisscrossing an entire ocean. There's a stunning diversity of animal navigators out there, often using senses and skills we humans don't have access to ourselves. For the first time, Incredible Journeys reveals the wonders of these animals in a whole new light.
