'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

Could be worse, if these animals had to put up with screaming personalities in a jungle.

Shows you what nature is really like , its not all fluffy chicks and adorable kittens , animals need food to eat just like humans , so welcome to the real world

So did the iguana live?

It was like a scene from a horror movie!

best piece of TV ive ever seen!

Snakes do not have the ability to share a meal. Therefore they are not co-operating in the hunt. It just a bunch of snakes trying to be first to grab the lizard.

outstanding!a truly talented crew who shot all the amazing footage in the programme.i was spellbound.....

Incredible viewing, especially in HD!

There have always been occasional scenes of animals chasing and eating each other as part of nature programmes over the past few decades. It's obviously not pleasant to watch but it is entirely natural and should not be omitted, regardless of the animals cuteness rating (such as in the case of the penguins). Far worse is that our screens are full of man-made violence in both films and news reports, and sadly there is a lot of deliberate cruelty to animals in the world. Nature is incredibly striking and sometimes sad or horrifying, but should be portrayed realistically.

I was enthralled from start to finish. Some lovely moments and some very sad moments - but that's nature in all its beauty and ugliness.

Really enjoyed the snake chase especially the one that got away against all the odds.

It was a very well made and edited piece of footage, I was cheering on that baby that managed to escape and then avoid recapture many times, what a start to life! welcome to world little one, now run for your life or 100 hungry snakes will eat you!

Proper television program at last!! Superb!!

Nature at it's finest...Brutal

Equally as awful is the seagulls slaughtering the baby turtles after they hatch and break through the sand for their run across the beach to the sea. Nature can be very cruel. Humans do their slaughtering behind closed doors to terrified animals en masse. And that doesn't even include the mass Hindu slaughtering of buffalo and other bloody practices for weird religious reasons.

those snakes reminded me of when a famous person dies and all the snakes come out to get some inheritance money.

Didn't know they could move so fast.

Welcome to the world. Poor little sods.

an amazing show and the scene with the snakes was brilliant camera work. The iguana's can run faster than the snakes,its just the amount of snakes that ambush them on the run to safer ground but as D Attenborough said there are thousands of adults so it seems there are a lot make it.Cant wait for the next episode.

True nature in the raw. Absolutely fantastic scenery and the penguins on the volcanic island were amazing to watch. Looking forward already to next week's programme
