David Attenborough introduces the colourful underwater world of Britain and Ireland's oceans, including thousands of grey seals congregating on the Norfolk shoreline to give birth. Rich beds of sea grass act as important carbon storage areas, as well as providing home for seahorses, while on the shallow seabed, the spider crab undergoes a mass migration of epic scale.

Our planet was once populated by megafauna, big top-of-the-food-chain predators that played their part in balancing our ecosystems. When those megafauna disappear, the result is a "trophic cascade," where every part of the ecosystem reacts to the loss. How can we stay in balance? George Monbiot suggests rewilding: putting wolves, lions and other predators back on top -- with surprising results.

From a primate that's no bigger than a mouse, to a chameleon that can fit on your fingertip, the natural world is full of fantastically small animals. Biologist Patrick Aryee explores the fascinating secrets behind these miniature marvels and shows that they're not the underdogs you might think they are. Super Small Animals follows him as he meets the leading experts on these pint sized superstars, and finds out what makes them some of the most successful on the planet. First up, he reveals the huge benefits that being small can bring. There's the little lemur whose diminutive frame helps it to exploit a unique gap in the eco-system, the tiny hummingbird that uses its size to out-manoeuvre the competition, and the world's smallest seahorse that never has to leave home. He also explores why small animals are proportionally the strongest in the world, and introduces a peanut-sized beetle that can pull over a thousand times its own weight. Next he explores the challenges that animals face when they shrink in size, and the ingenious ways they overcome them. We find out how the smallest armadillo in the world manages to control its temperature in the searing desert sun, and the how the world's smallest fish can survive in nothing more than a puddle, because it never really grows up. Patrick meets a secretive hippo that lives in the dense jungle, and looks like it's been shrunk in the wash, and some of the world's smallest snakes that give birth to enormous babies. He also meets a scientist that studies how really tiny spiders have a surprising trick that enables them to travel an incredible 40 miles per day, using almost no energy. Then there are the animals that refuse to be pigeon holed as small, and manage to punch way above their weight. He puts some astonishing invertebrates to the test, to see how they work together to become much bigger than the sum of their parts and meets a pint-sized predator that takes on some of the largest and most dangerous creatures on the planet, getting hands on to discover how its build helps it to be brave. Finally he uncovers the incredible lengths that deep sea anglerfish go to in order to be big and small at the same time, and has an endearing encounter with a tiny carnivore that manages to be small in just one direction. Whether their size helps them to hunt, hide or survive, all these remarkable animals prove that good things really do come in small packages.

The first episode tells how invertebrates became the first creatures of any kind to colonise dry land. Their forerunners were shelled and segmented sea creatures that existed 400 million years ago. Some of them ventured out of the water to lay their eggs in safety, and Attenborough compares those first steps with today's mass spawning of horseshoe crabs off the Atlantic coast of North America.
