Every year, in the middle of Croatia, it's the same story: after the annual snowmelt, a huge flood wave spills out of the Alps toward Zagreb and Belgrade. This leads to an increase in the River Sava's water levels of some ten meters. In the species-rich, alluvial flood forests of the last major meadow landscapes of the continent, enormous predatory fish like the catfish lie in wait for prey.

See the great migration as never before! The Mara River, nature’s best laid trap for migratory animals, is the stage for a grandiose spectacle. When food supply in the Serengeti dwindles, the Masai Mara is a paradise for predators. As the black wildebeests, gazelles, zebras and antelopes make their yearly trip from the south of the Serengeti to the north, nature’s best laid trap, the Mara River in Kenya is waiting ahead. Captivating shots filmed under water show how crocodiles prepare for the Big Hunt while other predators lurk on the banks awaiting their bounty.

The waters of the North Pacific around Canada's Vancouver Island are a strange and little known world. The water is incredibly clean, the location is isolated and huge thermal vents heat the otherwise cold surrounding these factors combined have led to animals and plants that can grow to huge proportions. Humpback whales, orcas, wolf eels and bald eagles all thrive here. Our team of experts go in search of the elusive Pacific Giant Octopus. Growing up to 7.5 meters across with the power to kill sharks, it is a formidable creature, but also intelligent and incredibly shy. The dive team invites us into an alien world, where persistence is rewarded with encounters with three of these magnificent creatures.

In warm waters around the world a cold-blooded killer hunts its victims. Mysterious in its movements, ferocious and feared, the terrifying Tiger Shark… distinctive in its dark stripes… These man-eaters are the stuff of nightmares… They can slip past our defences to savage us. Highly-adaptable hunters, they swallow up whatever they can catch. Even turtle shell is no defence against powerful jaws and saw-edged teeth.

For over 4000 years fishermen have been catching tuna during their migration through the Mediterranean. During the antiquity they were hailed as the "manna of the oceans". We take a look at the long journey of the tuna to its mating grounds and witness their struggles including massive amounts of hunters and the strong presence of fishing boats.
