During the rainy season in Africa, a herd of buffalo can create thousands of pounds of waste in a day, which would be an environmental disaster if not for the dung beetle. These extraordinary insects depend on waste to survive. They eat it, attract mates with it, and raise families in it. Although dung beetles are critical to the ecosystem, they don't have it easy. Every day, they must avoid being trampled, evade predators like bullfrogs, honey badgers, and rock monitor lizards, and rival dung beetle families desperate for the same fecal prize.
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.
David begins his journey inside the magnificent Palm House, a unique global rainforest in London. Here, he explores the extraordinary plants that are so well adapted to wet and humid environments and unravels the intimate relationships between wet zone plants and the animals that depend on them. It was in the wet zones of the world that plants first moved on to land and in the Waterlily House David reveals how flowers first evolved some 140 million years ago. Watching a kaleidoscope of breath-taking time-lapses of these most primitive of flowers swelling and blooming ...
Australia, a land cast adrift at the time of the dinosaurs. Isolated for millions of years, the weird and wonderful animals marooned here are like nowhere else on Earth. In its jungles a cassowary - one of the most dangerous birds in the world – stands six feet tall. Inland, kangaroos and wombats brave snowstorms and gum tree forests are filled with never-before-seen predators. In its red desert heart, reptiles drink through their skin and huge flocks of wild budgerigars swirl in search of water. On secret islands Tasmanian devils roam and offshore, thousands of sharks gather for a rare event.
There is an electric grid submerged deep within the Amazon River, made up of a fascinating community of fish that have technological superpowers. Biologist Will Crampton ventures into this world, one which few have ever seen, on a mission to find, catch, and study electric fish. Armed with his own electric devices, join him as he uncovers the fighting style of the jaw lockers, the navigational skills of the knifefish, and the remarkable hunting technique of the electric eel.
