Dangerous Marine Animals

Millions of tons of plastic slip into oceans every year.

Travel deep below the frozen tundra; see places rarely touched by humans and get dangerously close to the largest carnivore on Earth in Four amazing wilderness films!

At just 14 years old, when most boys his age would probably rather be riding bikes and playing video games, Jack Randall left his home in England to become an apprentice to "The Crocodile Hunter" Steve Irwin, learning to handle snakes and other reptiles. Today, Randall continues his research into exotic, endangered and iconic animal species by venturing into some of the most unforgiving environments on the planet.

In this journey, the secret world of Africa's largest and most-dangerous animals is revealed. From wild, grassy savannas to untouched beaches, these beasts show what it takes to survive in the elements and outwit natural enemies.

They are many. They are everywhere. And they're not killers: viruses. These artists of survival, as old as life itself, are the engine of evolution - including that of humans. "Viruses are the rulers of the world, they show us where to go." - This is how the renowned virologist Karin Mölling describes viruses in the film. The documentary undertakes a fascinating journey into the virosphere: marine biologists show the role of viruses as protectors of coral reefs of the world's oceans, and researchers have only recently discovered the importance of viral colonization in our intestinal system. Viruses have cured people from severe bacterial infections in Georgia for over a hundred years.
