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.

By telling the story of our organs, this documentary makes us aware of an evolutionary timeline. Our nose is 40 million years old, our coccyx 25 million, our fingers 370 million, while our chin is only 200,000 years old!

There is plenty of food in the Pacific Ocean, but it is the challenge of finding that food that drives all life in the Pacific. In the voracious Pacific we meet a destructive army of mouths, a killer with a hundred mouths and the biggest mouth in the ocean.

An extraordinary new discovery of a dinosaur fossil so pristine and complete, that it shows off the texture, patterns, and colour of a prehistoric giant. Discover this brand new species that roamed during the late Jurassic and Cretaceous periods. The Royal Tyrrell Museum in Alberta has spent five years and over 7,000 hours preparing the fossil for research and display.

In southern Africa, a pride of lions has rewritten the rules - by learning to take down elephants. In this follow up to Africa's Giant Killers, we join the pride at the start of the rainy season. As the elephants depart, a catalogue of dramatic events unfolds. The pride males turn against each other, an inexperienced mum puts her new born cubs in mortal danger, a rival group of lions challenge the pride for its territory and, when lightning strikes, fires burn day and night. When the dust eventually settles, the pride is left with only one choice - to face their old foe the elephants or risk starvation. The final showdown awaits.

Hummingbirds represent one of nature's most interesting paradoxes - they are the tiniest of birds, yet they qualify as some of the toughest and most energetic creatures on the planet. New knowledge gained from scientists currently making great breakthroughs in hummingbird biology makes this a perfect time to focus on these shimmering, flashing jewels of the natural world. Stunningly beautiful high-definition, high-speed footage of hummingbirds in the wild combined with high-tech presentations of their remarkable abilities help us to understand the world of hummingbirds as we never have before.
