Season 4 - Episode 4 - Aired 2/12/2018
Can animals count? This is a question that has intrigued and fooled investigators for a long time. Just over a hundred 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?

#4 - Incredible Shells
Season 4 - Episode 5 - Aired 2/16/2018
David Attenborough investigates two shells that have proved to be winners in evolution: the bird’s shell and the hard shell of the tortoise. The ostrich egg is so strong it’s possible for a person to stand on it without it breaking – 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.

#5 - Expandable Bodies

The bodies of some animals stretch and shrink in extraordinary ways. The anaconda can swallow prey twice its own body size - and then wait for over a year until their next meal. The camel’s curious hump can almost double in weight giving it the energy to travel huge distances across deserts. What is the secret behind these expandable bodies?

#6 - Curious Minds
Season 3 - Episode 2 - Aired 2/9/2015
Orangutans can use tools but such skills remained undiscovered for centuries. They were considered as just clever mimics until discovery in remote Sumatran swamps revealed their true potential. Clever crows also make surprisingly sophisticated tools. How have the curious minds of these two animals helped them become so inventive?

#7 - Extreme Babies
Season 4 - Episode 3 - Aired 2/12/2018
The giant panda gives birth to the smallest baby of any mammal and has to care for and protect it for many months. The kiwi lays one of the largest eggs in the bird world, which produces a very well developed chick. Why don’t pandas give birth to more developed, robust young and why do kiwis produce a single egg that is a quarter of its body mass and almost too big to lay?

#8 - Curious Cures
Season 3 - Episode 5 - Aired 3/2/2015
Humans are not alone in using medicines against injuries and infection. Some animals protect themselves with natural remedies in the most extraordinary ways. Hippos produce a blood-red “sweat” that acts as a sunblock and helps fight infections, while capuchin monkeys rub themselves with insect-repellent leaves to protect against insect bites.

#9 - Ferocious Fighters
Season 4 - Episode 6 - Aired 2/15/2018
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 – the most impressive male kangaroos are solid blocks of muscle with a kick that can kill. Why do they fight and what skills must a winner have?

#10 - Stretched to the Limit
Season 1 - Episode 1 - Aired 1/29/2013
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.

#13 - Curious Feeders
Season 3 - Episode 4 - Aired 2/23/2015

#14 - A Curious Hoax?
Season 1 - Episode 2 - Aired 2/5/2013
David discovers the curiosities that have led to accusations of forgery but have ultimately helped us rethink evolution. When early explorers brought the first specimen of a duck-billed platypus back to England in 1799, it was thought so bizarre it was deemed a hoax, while the midwife toad became the centre of a raging scientific storm in the 1920s that led to accusations of fakery.

#15 - Animal Frankensteins
Season 4 - Episode 1 - Aired 2/14/2018
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.

#20 - Impossible Feats
Season 3 - Episode 1 - Aired 2/2/2015
Fleas are supposed to be able to jump the equivalent of a human leaping over St. Paul’s Cathedral and cheetahs purportedly can clock speeds of 70 miles per hour. But are these claims really true? The discovery of the world's most elastic natural protein in insects and the development of a hi-tech tracking collar have helped reveal the truth. So can these creatures really achieve what should be physically impossible?

#21 - Finding the Way
Season 4 - Episode 2 - Aired 2/13/2018
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 manmade roads and hedgerows to find the quickest way home.
