Delving beneath the surface of the Earth's oceans to uncover a world of extraordinary extremes, including crushing depths, stormy coasts, vast blue deserts, and crowded reefs; how seals fend off sharks; how orcas fight to survive.
Chobe is Botswana's first national park, as well as the name of the mighty river that runs through it. Explore how its iconic species, like elephants, baboons, and lions, pass on their secrets of survival to the youngest members of their families.
We reveal the weird and wonderful stories of some of the natural world's incredible single parents: their devotion, dedication and often jaw-dropping endeavour in order to see their babies through to adulthood. From the slow loris covering her baby in toxic saliva to the Weddell seal putting her pup through winter boot camp, a weedy sea dragon cleverly camouflaging his eggs against his body and the female giant Pacific octopus sacrificing herself for her brood - we see how these parents are prepared to go the extra mile to arm the next generation with what they need to survive.
The riverbeds that carve their way through the Kgalagadi Transfrontier Park offer a tantalizing promise of life, as well as a fierce test of survival. Explore the hidden lifelines that create a fragile link for the creatures that inhabit this unwelcoming wilderness.
In nature, living long enough to breed is a monumental struggle. Many animals and plants go to extremes to give themselves a chance. Uniquely, three brother cheetahs band together to bring down a huge ostrich. Aerial photography reveals how bottle-nosed dolphins trap fish in a ring of mud, and time-lapse cameras show how the Venus flytrap ensnares insect victims. The strawberry frog carries a tadpole high into a tree and drops it in a water-filled bromeliad. The frog must climb back from the ground every day to feed it. Fledgling chinstrap penguins undertake a heroic and tragic journey through the broken ice to get out to sea. Many can barely swim and the formidable leopard seal lies in wait.
Sharks are among the most misunderstood predators on the planet, but an international team of scientists is trying to change that. Their research is revealing that sharks can be sociable and intelligent, and they could even help solve some of the toughest medical challenges of the 21st century. However, their breakthroughs come just as many sharks face extinction. Science may now be the only way to save them.
