Incredible Shells • 2018 • episode "S4E5" Natural Curiosities

Category: Nature

David Attenborough investigates two shells that have proved to be winners in evolution: the tortoise's shell and the shells of birds' eggs. The ostrich egg is so strong it is possible for a person to stand on it without it breaking, but how does the chick break out of this fortress? The evolution of the tortoise shell was for a long time a mystery and this bony box offers a lot more than just protection.

Natural Curiosities • 2013 - 2018 • 21 episodes •

Stretched to the Limit

Some animals appear to have taken Nature’s gifts and stretched them to extreme limits. With these two natural curiosities one creature, the giraffe, has ended up with a super-stretched neck, the other, the chameleon, a super stretchy tongue. In both cases nature has found a way to turn the ordinary into the extraordinary.

Young Wrinklies

David encounters two examples where Nature has tinkered with the aging process to alarmingly different effect – the first grows old while trapped in a young body while the second looks old from birth but might hold the key to a long life.

Nature

A Curious Twist

The single spiral tusk of the narwhal inspiration for tales of unicorns and the myriad variations on the twist of the snail shell have delighted and fascinated naturalists and artists since the dawn of civilization.

Nature

Seeing the Pattern

Zebra stripes vary subtly between the different species but there is one group of animals that has evolved colourful patterns of seemingly infinite variety, the butterflies. In this episode David looks at two examples of animal patterns that have bedazzled and baffled science for a long time, and uses modern tools to unlock their secrets.

Armoured Animals

This episode explores the story of two animals that hide behind seemingly impregnable coat of arms. Can Sir David Attenborough get in behind their armour and reveal their mysteries?

Nature

Curious Imposters

Here we discover that some animals are able to trick others into believing they are something that they are not. The art of deception is a powerful attribute for some.

Bad Reputations

After initially gaining frightening reputations, it's now known that gorillas and bats are a lot gentler and considerate than their early reputations suggest.

Nature

Shocking Senses

Plants and animals have some curious super senses that enable them to see, hear and feel things that are quite invisible to us.

Life on Ice

In this episode we explore the remarkable adaptations of two creatures that have evolved to survive the most challenging of conditions and seem to defy the laws of nature.

Nature

Spinners and Weavers

We'll find out how nature is incredibly inventive and has produced two unique mechanisms of natural construction that have fascinated scientists for centuries; weaving in birds and silk.

A Curious Hoax?

David Attenborough highlights the curiosities that have led to accusations of forgery, but have ultimately helped assist the rethinking of evolution. When early explorers brought the first specimen of a duck-billed platypus to England in 1799, it was considered so bizarre it was deemed a hoax. Similarly, the midwife toad became the centre of a scientific storm in the 1920s that led to accusations of fakery.

Animal Frankensteins

Hybrids can be bizarre and they can be deadly. We look at two hybrid animals that owe their existence to human interference - the pizzly bear (a cross between a polar bear and grizzly), which has come into being because of global warming, and the killer bee, brought into existence because of the transfer of African bees to South America.

Finding the Way

Some animals have an extraordinary ability to find their way. The dung beetle, an insect revered by ancient Egyptians, uses the sun, the moon and even the Milky Way to move its prized ball of dung in the right direction. Pigeons are often considered feeble birdbrains, but they have incredible memories that can recall several complex travel routes with amazing accuracy and they even use man-made roads and hedgerows to find the quickest way home.

Extreme Babies

The giant panda gives birth to the smallest baby of any mammal and has to care for and protect it for many months. Why don't they give birth to more developed, robust young? The kiwi lays one of the largest eggs in the bird world, which produces a very well-developed chick. Why do kiwis produce a single egg that is a quarter of its body mass and almost too big to lay?

Curious Counters

Can animals count? This is a question that has intrigued and fooled investigators for a long time. Just over 100 years ago, a German horse called Hans was declared a mathematical genius but all was not as it seemed. And strangely, some bamboos around the world flower exactly at the same no matter where they are. Are they counting down the years?

Ferocious Fighters

The Siamese fighting fish is so aggressive it will fight its own reflection until it is exhausted. Recent research shows that the fighting behaviour varies and depends on the personality of the fish! Male kangaroos were once pitted against humans in the boxing ring, with the most impressive male kangaroos being solid blocks of muscle with a kick that can kill. Why do they fight and what skills must a winner have?

The Great Dying

It is estimated that 99 per cent of species have become extinct and there have been times when life's hold on Earth has been so precarious it seems it hangs on by a thread. This series focuses on the survivors - the old-timers - whose biographies stretch back millions of years and who show how it is possible to survive a mass extinction event which wipes out nearly all of its neighbours. The Natural History Museum's Professor Richard Fortey discovers what allows the very few to carry on going - perhaps not for ever, but certainly far beyond the life expectancy of normal species. What makes a survivor when all around drop like flies? In this episode Professor Fortey focuses on a series of cataclysms over a million year period, 250 million years ago

Super Small Animals

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.

Snowball

In Snowball, Chris Packham tells the story of the astonishing moment in Earth’s distant past, when almost the entire planet froze – a glistening ‘Snowball Earth’ in the dark void of space. With ice wrapped around the planet to the equator, the chances of life surviving hang in the balance. Earth’s terrifying journey into the deep freeze started with fire, not ice. 800 million years ago, long before the age of the dinosaurs, before there was even animal life, the giant supercontinent Rodinia broke up. Earth’s vast powerful tectonic forces ripped the land apart, kicking off a series of events that resulted in huge amounts of carbon dioxide being sucked from the atmosphere and sending global temperatures plummeting. This plunge into the deep freeze couldn’t have come at a worse time. The very first forms of complex life - the ancestors to the amazing life we see around us today - were evolving but, as the planet froze to the equator, it looked like their days were numbered. Happily, Chris discovers that after 50 million years locked in ice, volcanic eruptions drove a great thaw. Life broke free from the ice and soon made a giant leap, from the microscopic, to the first animals big enough to see and touch.
