This is definitely the most thrilling thing you will watch today.
When iguanas are born, their first tasks involve evading death. This scary fact has been revealed in a new teaser clip for Planet Earth II, the BBC’s upcoming sequel to its legendary documentary series narrated by Sir David Attenborough.
It features one of the most incredible documentary shots ever: a hatchling iguana dodging death on what appears to be an island full of snakes.
Dramatic footage from the long-awaited BBC series 'Planet Earth 2' labelled 'the stuff of nightmares', showed a baby marine iguana attempting to outrun a knot of racer snakes on Fernandina Island.
It’s got excitement, tension, a hold-your-breath action sequence, and suspense all wrapped into a two-minute sequence and its ending must be seen to be believed.

When the crew saw the snakes for the first time, they were too shocked to film - and host Sir David had never seen anything like it either, it was reported.
And it seems viewers that tuned in were equally horrified - comparing it to a scene from a film.
Ken Early wrote, "This iguana/racer snake drama on planet earth 2 is like a Mel Gibson movie."
"I've still not got over that Iguana and snake scene from Planet Earth 2", posted Twitter user Lucy.
Stuart Ellis wrote, "Planet Earth 2, absolutely unbelievable. That snake bit was the stuff of nightmares."
The programme claimed a massive audience of 9.2 million and a 36 per cent share of TV viewers.
This made it Britain's most watched natural history programme in more than 15 years - and it was more popular than the first series debut watched by 8.74 million viewers.
The much-anticipated series, which is formed of six parts and follows on from the first Planet Earth in 2006, has taken three years of filming and 117 filming trips.
