Life in the sea rebounded with a vengeance in the Devonian. Dozens of monstrous predators emerged, like the 40-foot long Dunkleosteus. Nearly everything was wiped out in Earth’s second mass extinction. But the stage was set for an explosion of life on land.

Argentina's northern territory contains one of the largest reserves in the country. Ibera is a vast expanse of swamps, marshes and lagoons, with a biodiversity count to rival the Pantanal. These lands are bursting with life, home to over 4000 animal and plant species. The rainy season in Ibera finds the wetlands in bloom... but unseen perils lurk beneath the surface, and even here, life can be a struggle for survival.

The Auckland Islands are an isolated archipelago of islands far south of New Zealand. They might seem bleak, but they are a surprising sanctuary for wildlife. In summer, hordes of giant sea lions descend upon a desolate beach, and testosterone-driven males begin bloody battles for mating rights. When the pregnant females return to give birth on the beach, chaos ensues. The pups are always in danger of being squashed by overly eager males. Some of the rarest penguins on the planet, the yellow-eyed penguins, are also breeding here and must constantly evade the huge brawling male sea lions. Southern royal albatross, giant petrels and skuas are other species that go to extremes to ensure their offspring’s survival. The drama of summer in the sub-Antarctic islands peaks as the sea lion pups dare to take their very first ocean swims.

The next programme explores the various sea-living invertebrates. In Morocco, the limestones are 600 million years old, and contain many invertebrate fossils. They fall broadly into three categories: shells, crinoids and segmented shells. The evolution of shelled creatures is demonstrated with the flatworm, which eventually changed its body shape when burrowing became a necessity for either food or safety. It then evolved shielded tentacles and the casings eventually enveloped the entire body: these creatures are the brachiopods. The most successful shelled animals are the molluscs, of which there are some 80,000 different species.

Todd trains hard to improve his body intelligence, visualization skills, and emotional intelligence before attempting a super-human feat. He faces his greatest fear - being chained, handcuffed and blindfolded underwater with only his radically improved brain to help him escape.

How can you tell the two poles apart? Where are the penguins? What about the bears? The Arctic pole is located in the Northern Hemisphere within the deep Arctic Ocean, while the Antarctic pole is smack in the middle of the ice-covered Antarctica. Camille Seaman describes how enterprising people and organisms have found ways to reside around both poles despite the frigid temperatures.
