Venom expert Dr. Bryan Fry embarks on a dangerous island journey to uncover the deadly secrets of vipers, stonefish and the formidable Komodo dragon.

Hippos and crocs have lived side by side for millennia, but are they cozy bedfellows or arch-enemies? One is a hefty herbivore, the other is the most successful freshwater predator on the planet, so how do they manage to survive together in the same habitat? They each have a unique arsenal of attributes honed by centuries of evolution; muscle power, bite force and ferocious dentition give them the edge in their environment. But once a year, their peaceful semi-aquatic existence turns into a battle for survival.

Un survol de routine par drone vire au drame. Ryan Johnson, biologiste spécialiste de la vie aquatique basé en Afrique du Sud, filme un grand requin blanc en train d’attaquer et de noyer une baleine à bosse. Cette scène bouleverse complètement sa perception de la créature qu’il a observée toute sa vie. À la recherche d’explications, le biologiste suit la migration de baleines à bosse, cartographie leurs points faibles et jette un nouveau regard sur les grands requins blancs. Comment ces prédateurs se transforment-ils en tueurs de baleines ?

Incredible Insects A captivating world of creepy crawlies exists all around us. And they are the biggest group of animals in the world, outnumbering humans 200 million to one. Thanks to millions of years of evolution, these invertebrates not only survive in almost every landscape known to man, but also thrive by means of fascinating, and sometimes bizarre adaptations. There's the Bombardier beetle that squirts a boiling hot liquid from its anus, the Assassin bug that turns its victims into soup, and the Parasitic wasp that lays her eggs inside her victims, until her young are ready to eat their way out. We end off with the biggest bugs on the planet: the Atlas moth with a wingspan of over 20 centimetres, the Hercules beetle that can carry 850 times its own weight, and the Giant centipede - big enough to catch flying bats from midair!

S'étendant sur six pays et plus de trois millions de km2 de forêts, de rivières et de plaines inondables, l'Amazonie abrite la plus grande diversité de vie sur la planète. Professeur de biologie à l'université d'Orlando, en Floride, le Dr Will Crampton étudie depuis plusieurs années des espèces aquatiques de ses rivières, lesquelles sont dotées d'une arme secrète redoutable : l'électricité. Grâce à elle, ces super poissons peuvent communiquer, mettre en garde ou tuer concurrents et proies, et émettre des chocs si intenses qu'ils peuvent même arrêter le cœur d'un humain.

Dix ans après la découverte stupéfiante d'un coelacanthe vivant, pêché au large des côtes sud-africaines, le zoologiste et plongeur Dr Richard Pyle se prépare à explorer les fonds marins pour trouver cet animal d'une autre ère. Il était déjà connu de la communauté scientifique, mais uniquement sous forme de fossile et on pensait qu'il avait disparu avec les dinosaures. Pour rencontrer l'animal, l'équipe devra plonger à 120 mètres environ sous la surface, une profondeur réellement dangereuse pour le corps humain... Mais une telle mission ne saurait se dérouler sans difficultés.

The ragged-tooth shark has a formidable reputation – but the truth about this animal is very different. We follow this incredible shark on its biannual migration along the South African coast and venture deep into underwater caves to study its dramatic mating behaviour.

In Rwanda, Africa, a new era is dawning after a brutal civil war ripped through the country, killing close to two million people and wiping out its most iconic wildlife: the regal lion. Now, 25 years later, the big cats are being reintroduced to the region to reclaim their throne. Follow this magnificent seven, a collection of five females and two males, as they travel thousands of miles from South Africa to Akagera National Park and attempt to figure out their new land, form relationships, and restore the pride of a nation.

A male lion cub is born into a powerful pride and quickly establishes his dominance over his siblings. But after a fight with his father, he is immediately banished from the pride. How will he cope with the brutal reality of the African savannah

Cuba's enforced isolation has resulted in the unlikeliest of marine reserves: a huge, rambling archipelago known as Jardines de la Reina, or "Gardens of the Queen." Stretching around 140 miles along the southern coast of Cuba, it's one of the longest barrier reef systems in the world. Get an up-close look at Fidel Castro's diving playground, a forgotten ocean paradise unseen for half a century, and witness exotic species rarely seen elsewhere in the region. It's the lost jewel of the Caribbean, but how long can this pristine wilderness survive?
