Antarctica – the coldest, windiest place on Earth is home to the Emperor Penguin. As the sea freezes over at the start of winter, the Emperors return to their colonies to breed, travelling 60km or more across the ice to get there.
Humpback whales’ hearts weigh over 200kg, their lungs are each the size of a car. They also have huge appetites and can eat 1,300kg of food in a single day. They have hundreds of overlapping plates in their mouth – and feed by gulping about thousands of litres of water in a single mouthful and then filtering out their tiny prey.
The Australian greater bowerbird works tirelessly arranging the grasses and sticks that make up the walls of his bower. He is always on the lookout for anything shiny or colourful to hang on the walls and impress his female admirers. He has to fiercely protect his bower from an inquisitive bush turkey and passing snake.
The Orca is a toothed whale – and is such an efficient predator it can kill other whales bigger than itself. Sperm whales are the largest of the toothed whales and weigh up to 40,800kg. The Minke Whale is the smallest, but most abundant baleen whale with an estimated population of 800,000 world-wide.
