Hunting for it in the piranha-infested waters looks like no fun at all, but some of the images we see of astonished fish along the way are brilliant.

On the other side of the world under the crystal clear blue waters of the Pacific Ocean lies one of the most enchanting places on the planet. Over ten thousand miles away on the north eastern coast of Australia lies the Great Barrier Reef, one of the natural wonders of our world. It provides shelter to some hidden wildlife sanctuaries that contain some magical marine creatures. Iolo Williams dives deep beneath the surface of the coral sea to discover what state this natural wonder is in. He travels from the extreme swells of the northern part of the reef right down to the cooler pristine corals of the south. He discovers how healthy the Great Barrier Reef really is in some of its key locations to see and find out if there are real signs of hope the reef can survive the threat of global warming.

More than a billion people around the world commute into cities each day, and they are not alone. The world's wildlife is commuting too. A steady flow of animals journey in and out of cities to find food and shelter or to start a family. Leaving the wilderness they must overcome the unique challenges that the urban world throws at them to benefit from the opportunities on offer. This episode explores whether the secret to an animal's success in this fast-changing world is to keep one foot in the wild and one in the city, becoming a wild commuter. It seems that all over the world animals are finding that the city can offer opportunities that are harder to come by in the natural world. Some, like African penguins, whose population has plummeted by 80 per cent in the last 50 years, find shelter in the city. By nesting in Cape Town they are safer from predators, and with relatively easy access to their fishing grounds they have the best of both worlds. Many other animals commute into cities because they are filled with food. In St Lucia, South Africa, that includes hippos. Able to eat up to fifty kilograms of grass in a single sitting, they have developed a taste for the short, manicured lawns and come to town every night to dine out. St Lucia's human residents have learnt to give the hippos the space they need during their night-time raids. Black bears need to eat more than 20,000 calories a day to survive their six-month hibernation through winter, and using their acute sense of smell they can easily track down leftovers. In North America they come into towns and cities in search of food. Many animals displaced from their natural habitat are now using their wild skill set in the city to help fulfill their needs. Could this be the beginning of a new and very modern migration?
