Second series of Planet Earth takes viewers on a journey through jungles, mountains and islands
A DECADE after the first Planet Earth series was filmed, Planet Earth II has arrived on the BBC, with David Attenborough returning to narrate and another score by Hans Zimmer.
Here's everything we know about the wildlife series, including THAT harrowing snake/iguana scene.
When is it on, and where can I watch it?
The series began Sunday, November 6, at 8pm on BBC One.
The fourth episode, Deserts, will air Sunday 27 November.
A new episode will air at the same time each week for six weeks, once an episode airs it will be available to watch on BBC iPlayer for 30 days.
What is this series about?
The BBC has said that Planet Earth II reveals our planet "from a completely new perspective, using significant advances in both filming technology and our understanding of the natural world."
Charlotte Moore, one of the producers, added: "This new series promises to be an extraordinary experience for our audience. Filmed over three years across the globe with all the very latest technology, the series uncovers stories about the natural world we have simply never been able to witness before."
The series takes viewers on a journey through jungles, mountains, islands and cities, exploring all the habitats of the world and how animals survive in them.
Planet Earth II promises to give fans the most immersive wildlife documentary experience to date.
New camera technology means that audiences are being taken closer to nature and experience it as if they were there.
The BBC said the original series, first shown a decade ago, "redefined natural history film-making, giving us the ultimate portrait of life on Earth".
It was also the most expensive documentary ever broadcast, costing £20million and taking five years to make.
What's happened so far?
Episode 1, , took a look at creatures on remote islands, including penguins, sloths and albatross.
Fans of the show were on the edge of their seats as dozens of racer snakes chased newly hatched marine iguanas on the Galapagos Islands.
Viewers were also left heartbroken by a penguin's struggle to feed its family on the sub-Antarctic island of Zavodovski.
Episode 2, Mountains, offered a glimpse into the lives of mountain animals, including snow leopards, grizzly bears and golden eagles.
Episode 3, Jungles, took viewers to "flooded forests [that] are home to caiman-hunting jaguars and strange dolphins that swim amongst the tree tops". It also examines ninja frogs, indri (the world's largest lemurs), flying dragons, unusual fungi and glow-in-the-dark creatures never before caught on film.
Episode 4, Deserts, showed how animals come up with ingenious ways to survive and flourish in some of the world's most hostile conditions.
The episode featured stunning footage of a giraffe making a heart-stopping escape from a pride of lions' ingenious trap.
With its life in the balance, the giraffe shook off one of its would-be killers and then trampled another as it made a daring getaway.
Episode 5, Grasslands, took viewers from the saiga antelope of Asia to Brazil's giant anteaters.
Fans were divided over spectacular, but gory scenes which showed five lionesses trying to take down a huge Cape Buffalo to feed their hungry young cubs.
Episode 6, Cities, gives an insight into the lives of animals who share their habitat with us – from Albi in France to New York.
A harrowing clip released ahead of the episode shows a leopard snatching a piglet from beneath its mother in Mumbai, India.
