'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

Horrific to watch. Still shocked from last night's program. Worse than a nightmare!! Poor little babies...... they knew they had to run to live. I enjoy pleasant programmes, sorry. Happy animals......... yes please. Nature is indeed mainly nasty..... most must chase, kill or eat alive another animal to live!! Horrible, just bloody horrible!

Reminds me of women chasing men with money

I'm not "terrified"; but I AM "amazed" that there are wimpy numpties who think this is bad. If you want to see pack mentality, go take a dekko at the local benefits office on payout day.

ThePC brigade who is shocked by this should visit their local abbertoir or wrap themselves in cotton wool and forget where meat comes from. This is real which so many people do not want to face. Reality

The Iguana reminded me of the Brexit vote with the Europhile Westminster snakes trying to constrict the life out of it....

I've never liked snakes - sorry snakes but you just aren't likeable

Lilly Allen was up the top of the hill to comfort the lizzard

David Attenborough absolute legend !

Snakes do not hunt in packs...EVER...they all just happen to be hungry and trying to get the food first...Animals that hunt in packs share their kill...snakes do not do this

I'm confused, I thought the Daily Mail & it's readers hate the BBC & would like to see it shut down. And the fact is that it is unlikely that any other broadcaster in the world would make such a program. My message to DM readers; Be careful what you wish for.

Nature's not all Walt Disney you know.

It was the komodo dragon scene that scared the bejeezus out of me!

Television at it's absolute finest & worth every penny of my TV license.

We had a huge snake as Prime Minister...they called him Tony.

We know it goes on but nature is so damned cruel. I hate to see any living creature suffering terror

You can't call it disgusting! Its just nature!

I may never recover... ever.... from some of those sights and who knew we would be cheering on a sloth....#lifeisharsh

Fantastic episode, if the rest of the series is as good we're in for a real treat :) I did wonder, how did they know they had to run, they've just hatched haven't really found their legs and then the poor things had to run for their lives, I guess it's a built in instinct. I didn't know I could feel sorry for red crabs either, but then until last night I knew nothing about them, but it's man who has caused the problem by bringing the ants there ....

Planet Earth was beautiful once, then one day the Human Race turned up.....

Run! Run! Oh, I'm going to have nightmares tonight....
