The world of the armoured creature is equally fascinating and bizarre. Galapagos giant tortoises solve the problem of making love in a suit of armour; a heated sea turtle orgy leaves females in mortal danger and we witness the explosive arrival of a baby pig-nosed turtle. Giant salt-water crocodiles crowd a flooded river-run to fish for mullet and a caiman leads her brood in a touching trek to a communal crèche.
Sixty-six million years ago, an asteroid wiped out the dinosaurs in a fiery global catastrophe. But we know little about how their successors, the mammals, recovered and took over the world. Now, hidden inside ordinary-looking rocks, an astonishing trove of fossils reveals a dramatic new picture of how rat-sized creatures ballooned in size and began to evolve into the vast array of species.
David Attenborough takes a breathtaking journey through the vast and diverse continent of Africa as it has never been seen before. (Part 2: Savannah) East Africa is a land which is constantly changing. To survive here, creatures must be able to deal with unpredictable twists and turns - wet turning to dry, feast to famine, cold to hot - no matter how hostile it becomes. From dense forests to snow capped peaks, steamy swamps and endless savannah, this unique and varied land is also a haven for life, supporting large animals in numbers found nowhere else on Earth. But away from the familiar, forever-travelling herds, there are a huge cast of other characters - lizards that steal flies from the faces of lions, vast dinosaur-like birds who stalk catfish through huge wetlands, and an eagle who risks everything on the arrival of ten million bats from a far off rainforest.
At the southern tip of Africa, where two oceans collide, the flat-topped Table Mountain stands guard over a diverse metropolis of cultures and people. Take flight over the Western Cape and discover the breathtaking wonder of this province from above.
Beneath Indonesia's coral reef, tiny creatures have made the murky seabed their home. Here, you'll find shrimps that kill with a whip-fast punch, toxic nudibranch sea slugs, and six of the nine species of the world's walking sharks. Dive into the depths of this unlikely ocean ecosystem.
