Journey into the abyss to see strange creatures, many of which are new to science. Including terrifying fish with massive teeth that eat prey twice their size and strange jellyfish that flash in the darkness. See the deep sea sharks that have never been filmed before and discover the submerged mountain ranges and volcanoes far larger than anything on land.
Each and every animal is born with a chance: to survive, thrive and produce their very own next generation. The first hurdle in life is infancy. Vulnerable, naïve but determined, some young animals face their biggest challenges in the first few days of life. How a creature fares at the very beginning is the foundation upon which their future success depends.
A spectacular natural event takes place in North America every year as hundreds of millions of salmon return from the Pacific Ocean to the mountain streams where they were born. The salmon must overcome fierce torrents and leap over waterfalls as they make their way upstream. The great run not only provides food for bears, but for killer whales, wolves, bald eagles and even for the forest itself. A family of bears is filmed from the air as they make a treacherous journey to the coast to await the return of the salmon.
North Africa is home to the greatest desert on Earth, the Sahara. This vast wilderness, the size of the United States, is the toughest part of the African continent – the sun rules mercilessly here. In this haunting wilderness, dunes ‘sing’, sandstorms stretch for a thousand miles and rain may not fall for 50 years. In the heart of the Sahara very little life can survive the sun’s onslaught. Just one animal takes on the midday sun, and it needs a ‘spacesuit’ to do it. The silver ant waits until all other creatures have fled the scorching dunes before finally emerging to feed in peace.
