'A real life horror film': Terrified viewers watch from edge of their seats as SNAKES hunting as a pack chase down baby iguana in amazing footage for BBC's Planet Earth II that even shocked Sir David Attenborough

Nightmare.. please! this is the reality of survival and natures way, the snakes have to eat too! Absolute fantastic show though beautiful filming at its finest! loved it

I doubt Sir David was shocked_ he has seen far worse things I'm sure. I watched the programme_ it was a great start. Hope the series continues in this vein. IT IS WHAT HAPPENS_ life (and death) are facts. If you don't want the facts don't watch.. and maybe enter a "closed order" (though even there you'll find nasty things happen).

OMG. I can't believe I've looked at the pics, just couldn't view the video......they are my worst nightmare along with worms....eah....I'm a keen Gardner too. I can do spiders ha!

I watched this last night. Heart-stopping stuff, wasn't it!

This is what hell looks like. Snakes and red hot lava. Yikes!

Kill or be killed. First law of nature?

I couldn't bare to watch...did he make it? :Z

The ONLY time I have ever rooted for an iguana. I cheered when that one escaped at the end. Now let's play the same game with Gemma Collins and Kerry Katona and see if the snakes get them!

felt like i was watching a movie for 30 seconds intense!!!

I hate snakes but was on the edge of my seat as could not imagine the horror of "en masse" hunter, killer scenario!

this is what a reality programme is all about, not under dressed and un educated idiots from Essex, Newcastle, Chelsea - take your pick....they have the morals of a snake, in all relationships.

I was screaming for the poor iguanas... the last one that got away, was epic. Those snakes were fast, very fast indeed.

It's survival of the fittest on the Galapagos islands. Ask C ha r l e s D a r w i n .

Edge of the seat stuff. I have to say when I first saw it I thought that it was perhaps photoshopped. To realise that, that was what actually happening was terrifying. Poor iguanas. My heart was in my mouth. But in the end those snakes have to eat just like anything else that lives and breathes and walks the earth. Love David Attenborough. I have missed him these past few years whilst he was away filming.

Horrific but absolutely fantastic television!

sssssssssssensational.

Never felt so many emotions in one hour watching a wildlife documentary. Superb camera work, well done to everyone involved. D. IOW.

Watched in horrified fascination! Never seen anything like it before. The way those snakes heads shot up in unison... aarrgghh! Luckily didn't dream about them - but really thought I would (shudder..)!

I'm glad he/she got away when the snakes seemed to get wrapped up in each other phew! and who knew sloths could swim! I do now.

its a bit like the american election who do you want to win - the snake or the lizard
