The rivers of Africa bring life and abundance to their inhabitants, but they can also be the arena for some of nature's greatest challenges and dramas. Harsh seasonal cycles dictate life - and death - along the rivers. Only the fittest survive crossing the crocodile-infested Mara, the extreme drought of the Luangwa Valley or any of the many other perils harboured by waterways all over the continent. Africa's Rivers is a predator's world with cunning and opportunistic hunters of all sizes lurking in the waters or prowling the banks.

Thirst overcomes the hordes of Wildebeest and Zebra moving through Kenya's Masai Mara game reserve on their spectacular annual migration. With the cycle of the seasons comes the dry months, the water of the marsh receded. Now the residents of the marsh face a time of hardship, food will be scarce, until the next rains fall.

Cameraman John Varty spent five years making this documentary about Africa's elusive, silent hunter, the leopard. Footage of leopards mating at night, raising a litter of cubs, interacting with hyenas and going for the kill.

To the ancient Egyptians, the crocodiles of the Nile were river gods. Now residing in the Ndumo Wildlife Sanctuary on the South African Mozambiquan border, these prehistoric reptiles live a harsh and difficult life. When a young female crocodile risks her life to mate with the biggest male in the group, she is in direct competition with older and larger females. It is an ambitious strategy of survival that could pay off - if her young brood makes it to adulthood.

It captures some of the most extraordinary scenes ever seen on film of these predators hunting and killing. This award-winning program, filmed at Londolozi Game Reserve in South Africa and Kenya's Masai Mara, features the "big five" super predators: lion, hyena, wild dog, leopard and cheetah. The film includes a place for a man to work in closer partnership with nature for our mutual benefit and survival.

Lazy relatives. Jealous neighbours. Runaway kids. The everyday troubles of one family - except this family is a pride of lions. Shot over three years during the most extreme seasonal changes in Africa, the film follows Mfumu - the pride's leader - as he struggles to defend his turf and his mate Chipazuwa as she tries to produce offspring. Among the threats is a river infested with crocodiles that have taken every litter of cubs -- and a rival male is bent on taking over the pride.

Ele Tele is a 52-minute film that will give viewers an elephant's eye view of the Kruger National Park in South Africa. Using a specially constructed camera and microphone rig attached to the elephant matriarch named Ellie, the film crew and scientists capture every event in the life of a family of elephants.

This is the story of Ella Addison, an extraordinary 12-year-old girl who swims with sharks. It is a family tradition. But something strange is happening around her Shark Rock playground. Blacktip sharks are multiplying, and tiger sharks are disappearing. Curious by nature, Ella starts a school project to solve this mystery. Usually, blacktips migrate to Shark Rock for the sardine run and then move on. But in recent years, they are staying put, which means tiger sharks are being forced out. So, where do the blacktips come from? Jessica Escobar, a feisty Columbian marine biologist, doing her doctoral thesis on blacktips, and Ella makes a formidable team. While Jessica compiles and analysis the genetic information, Ella compiles a visual diary of her dives on Shark Rock to present to her school.

Groot nommers van seekoeie is besig om dood te gaan en hulle karkasse word al langs die rivier gevind tot die genot van die krokodille. Wat is die oorsaak van hierdie ongewone sterftes?

At Londolozi Game Reserve they experience a close interrelationship with the animals and this is the window which allows them into the secret life of the magnificent Leopard Lula.

Lions, cheetahs and leopards: each cat has its own special hunting strategies, family upbringing and survival techniques. We focus on their behaviour and competitive interaction in our quest to find out who the ultimate predator is in the daunting wilderness of Africa. We follow their lives as they play out like a game of chance.

For millions of years, herbivores and predators have competed in an arms race, and over time, they developed specialised survival techniques and super-human abilities. They can see, smell and hear with telescopic vision, advanced radar and instant wireless communication, the real bush telegraph. Sense and Scentability explore the phenomenal world of animal super-senses, looking at dramatic footage of the hunters and the hunted square off against each other in Africa's great wilderness area.

Fast and efficient, an ocean legion is on the move. Growing in momentum, single pods congregate to find food. Combining in battalions over 3000 strong, this is the Dolphin Army. Filmed over 3 years during the spectacular Sardine Run along the eastern coast of South Africa, Peter Lamberti and his team have filmed one of the fastest predators in the ocean - the Common Dolphin. Using advanced underwater technology, they follow a small group of female dolphins as they battle shark threats, raise their calves and journey towards the greatest feeding opportunity in the ocean.

200km from the southernmost point of Africa, where the water is chilly and harsh, runs the Breede River. Recently, reports have been made of a massive creature living in the river. Fish are being taken off fisherman's lines - but with a curious and sickening twist. Only the bodies are taken: the heads are being left intact. The picture that sends aquatic ecologist Andy Coetzee off on the quest shows the head of large kob that has clearly had its body ripped off by something even larger. With shark hunter and expert fisherman Hennie Papenfuss at his side, Andy sets out to discover the truth behind the tales and exactly what the monster could be. Following the science and the rumours, this dramatic aquatic adventure joins Andy on a journey that follows the coastline of South Africa from north to south, and the sharks who are in turn following the fish.

On Zambia's Liuwa Plains, two star-crossed spotted hyenas begin their lives. A little female we have named Nasanta, and a male we named Twaambo, are born to warring rival clans. In the female-dominated hierarchy of spotted hyena society, males are doomed to harassment, abuse and rejection by their clan; whilst females fight for rank in a comparatively charmed existence. We watch as Twaambo and Nasanta, grow up worlds apart because of this unique dynamic, as their clan's struggle for food and territory in the extreme Liuwa environment. Desperate drought, raging fires, relentless flooding and territorial warfare are just a few of the challenges Twaambo and Nasanta's clans must overcome, as the cubs grow to adulthood in the Realm of the Bonecrusher's.

Powerful. Deadly. Elusive. Manana is a wild leopard. She could kill a man with ease. Yet besides her sits JV, unarmed and unharmed no bars, no cage. She gently brushes past him, almost touching. Today she will allow him to join her as a hunter, a privilege rarely bestowed on fellow leopards, let alone a human. John Varty, wildlife cameraman, has a unique friendship with this wild cat and has gained access to the mysterious world of one of nature's most enigmatic animals.

Following Lucy, through the major challenges of her life, we witness her first steps out of the nest, her first swim and her triumphant journey to independence - out on her own - in the dangerous ocean.

Afrika is ‘n land van reuse. Sy kragtige riviere kerf die aarde en vorm indrukwekkende valleie en waterwieë wat ‘n tuiste is vir menigte treffende en magtige inwoners. Hierdie is die riviere waar reusagtige olifante en seekoeie bly, eet en drink, en waar antieke krokodille jag en voorplant. Hulle deel die riviere met ystervarke, die breëkoparend, en die luiperd.

The world's tropical waters are inhabited by a fish that dwarfs all others, yet the tiniest creatures fuel it. The whale shark spends its life pursuing rich upwellings of microscopic plankton. Off the east coast of Africa, the warm currents of the Indian Ocean carry with them a seemingly infinite supply of food. Each year, with the onset of spring, the gentle giants leave the equatorial waters of Seychelles and follow these currents southwards, on a remarkable journey, unique in nature, thousands of miles along the ocean's highways. Our story follows one whale shark on its trip to the southernmost tip of the continent to unravel the mystery of the whale shark's incredible journey.
