Who else is useing his voice to fall asleep?😂

The footage 10/10 The Sound Design 10/10 The Narration 100/10 Making this free for us to all enjoy 10/10 Thank you so much BBC, David Attenborough is a gem and a one of a kind human being <3

The cuttlefish along with many other sea creatures are perfect depictions of alien creatures you've simply grown accustomed to.

Can you give a thumbs up not only for Davids narration but for the utter brilliance and sheer dedication of the camera people who capture this incredible footage. Truly masters of there art.

There's just something about David's narrative expression, with whatever the subject is. Makes Everything so much more Compelling and Fun!! ❤

Sir David has educated so many people across our planet, it’s unfathomable. Not to mention the spark of interest he’s more than likely ignited in thousands of youngsters to become biologists, palaeontologists, scientists, geographers, zoologists etc What a marvellous man that we’ve been lucky enough to ‘know,’ a true legend.

Unbelievable footage, it's hard to imagine how much time and research goes into just getting one shot. In the 8th minute, all those crabs, and then that Stingray glides in from nowhere and dwarfs all the crabs, like a patrolling alien. Just incredible.

I'm not a crab but that cuttlefish hypnotized me.

THANK YOU DAVID ATTENBOROUGH for all the narrations you have done over the years and the many more to come

everyday I find a new reason to love this planet and appreciate everything we have here, it is such a honor and a privilege to be able to see some of the things bbc and others give us to view. Thank you a million times over!

Jellyfish are deadly, but so gorgeous. It’s like a villain from a story that you can’t help be captivated by.

I worked one summer at a science center and the curator was a guy named Mobley. He had a thick beard that I asked him about, because it was so hot and he looked miserable. He pulled it up under his chin and showed me how his skin looked like scars from 3rd degree burns. It went down his chest and back in strings in some places. He was in Brazil doing research and while swimming one day had one tentacle from a Man a War hit his arm. He felt the pain ,but when he tried to pull his arm away it just pulled the rest of it on to him. He said that it came close to killing him, but during the 3 hour ride to a hospital he said he prayed for death. Said the pain was indescribable. I will say it looked bad. Like someone pulled super heated wires over his skin. It wasn't floating on top, but just under the surface.

David Attenborough is my absolute favorite narrator 💯💯

Only the BBC can do this type of nature programme successfully. The best camera technicians, and Sir David Attenborough's unrivalled narration.

Nature is such a miracle I can't help but weep as I watch these

I love David Attenborough so much man, GOAT narrator

Incredible footage. Sea life is beautiful, yet dangerous. I never tire of the Sea. Thank you.

Thanks to bbc for uploading this on youtube. Such Awe-inspiring documentaries need to be appreciated by the entire humanity. Kudos to Sir Attenborough and the entire team for their dedication and commitment. Great work🎉.

All of these epic shots and cinematography are truly amazing. But without David’s narration it wouldn’t be the same. It’s crazy how dependent these sort of documentaries are on their narrator.

I never knew how much I needed to see hopping crabs until now. They're so cute
