Mysteries of the Twilight Zone | Worlds of the Deep

In the deep ocean, life is concentrated at chemosynthetic oases where primary production is made possible via chemosynthesis at cold seeps and deep sea hydrothermal vents. The non-chemosynthetic regions of the deep are divided into two very different worlds. First is the midwater, where pelagic wanderers tread migratory routes that span entire oceans, and planktonic drifters and their predators take part in bioluminescent light shows. It is separated into zones based on depth, including the sunlight zone (epipelagic), twilight zone (mesopelagic), midnight zone (bathypelagic), abyssal and hadal zones. And below, lies the deep sea floor. A kingdom of mud and ooze, where sessile creatures cling to any solid outcrop and corals craft kingdoms on the seamount crusts. The worlds of the deep sea could not be more different, and yet their stories are fundamentally intertwined. In this episode, we delve into the Twilight Zone.

Written, narrated and edited by me, Leo Richards. This channel (Natural World Facts) is a solo passion project dedicated to exploring the wonders of the natural world and telling stories that inspire! I'm so excited to share this series with you at last.
Schmidt Ocean Institute (SOI) is a non-profit oceanographic research foundation that has been pioneering deep-sea research and discovery since 2009, on board their old vessel RV Falkor and their new RV Falkor (too). Their remotely operated vehicle (ROV) SuBastian is equipped with a suite of sensors and a 4K camera that has illuminated the depths and live-streamed dives around the world. Most footage shown is filmed and provided by SOI. Huge thank you to them for contributing their footage, and working with me to create this series! Check out their website: schmidtocean.org/

Hi all, I’ve been working on this film for 4 months, balancing it with University and other films, so I’m super excited to share this at last! Do let me know if you enjoy. It’s been a pleasure working with Schmidt Ocean Institute and the breathtaking raw footage they so kindly provided. Episode 2 - the Midnight Zone - is underway and I can’t wait for you all to see that too!
-
This is what I’m looking for. No dramatised tv films, just facts about the natural world beautifully put together.
-
I’m one of the ROV pilots for SOI. That siphonophore was longer than 50m. That was just the outer ring. That glass octopus was also much bigger than 40cm. What a great video. Thanks for putting all that together

"The deep sea floor is, at first glance, a place of filth and decay -- destitute, perhaps, and full of horrors. But if we look a little closer, we uncover a place of beauty -- a realm where corals craft mighty kingdoms on the seamount crusts; where the delicate structures of sponges provide refuge for others; and where scavengers attend bountiful feasts that last for decades." This is just achingly poetic.

The production value in these videos are insane. Well done!
-
Grab your popcorn and goggles, everyone!! It’s going to be phenomenale
-
Thank you for presenting nature and ocean life in a way that doesn’t make everything seem weird, creepy, alien and crazy. I have dearly missed more matter-of-fact and down to earth presentations of nature that were lost for a while during the reality tv booms that gained foothold in discovery and animal planet. I love your channel so so much. I can’t wait for more

the baby jellyfish being born at 15:49 and starting to swim was too adorable i started crying

What a wonderful addition to your already fantastic channel offerings, Leo! Mesmerizing and beautifully produced as always. I am absolutely awed by the amazing variety and beauty of the deep ocean's inhabitants, and truly appreciate your efforts to showcase them for us. I'm eagerly anticipating the next episode!

I'm only a bit over halfway through, but I wanted to say — beautiful work. You have such a knack for making these videos. I was completely enthralled (the footage of that Glass octopus took my breath away)and you've completely captured that childhood wonder I had while watching documentaries like this as a kid. Even how you narrate is perfect; gentle, clear, and slow. You've made something absolutely beautiful.
-
I really enjoyed this entire video. The stunning otherworldly footages, calming music and your soothing voices. Looking forward to the next episode!
-
These documentaries are amazing. Honestly one of the best nature documentaries I've ever watched.
-
Whoever did the sound design for this video did an amazing job. Really well done sound effects and background music to keep people captivated.
-
It's like watching from a museum show, always fascinated about the water world.
-
this film is so beautiful. the sound design, music, narration, and footage are all so breathtaking. the creatures are described with awe and respect instead of fear or discomfort. it’s very refreshing to see. i’m excitedly awaiting the release of the second episode!!!
-
I’m currently in the hospital recovering from a surgery, and this is such a good watch! Absolute gem as always ❤
-
I have been so excited for this! Your work is absolutely fantastic and your dedication to providing high quality, free nature documentaries is wonderful! Thank you!
-
I would advise watching this with headphones. I decided to wear mine today and wow, I hear ocean sounds I never heard before. Your voice never disappoints - has a lovely, soothing quality. Channel is always interesting.
-
This is the best channel I've found in a while. Incredibly written, narrated and edited.
