Deep sea (abyssal) gigantism demonstrates the role of natural selection in driving evolution and survival, particularly in an environment characterised by challenging conditions and limited resources. Evolution tends towards the most effective adaptations to grant animals the best chances of survival. And whether large or small, evolution selects for the best-adapted body size to survive these conditions. Though widely debated and often controversial, the research that has been done into the science behind deep sea gigantism has significant implications in the human world; it is believed that climate change may have a greater impact on ocean dwellers than any other population of animals. As the colder oceans warm up, the balance of temperature, oxygen supply, and what organisms are present, will throw the equilibrium off course. And the giants, which rely so heavily on this fine balance, may be the first to go.

This one has been a long time in the making, I really hope you enjoy! I covered Deep Sea Gigantism in my first ever deep-sea film 2 years ago, and felt it needed a remake to do the topic justice. So sit back, relax, and prepare to immerse yourself in the wonders of the depths for half an hour. 😊

Such a coincidence that just an hour or so ago I decided to rewatch the first one because I remember how well done it was. Perfect timing.
@Chris No way, that’s awesome!! I would LOVE your thoughts on this one versus the original, if you’re willing to share 😁
@@NaturalWorldFacts Definitely. I'll do that when I wake up with a clear mind since I watch thee before I go to bed. I enjoyed this one very much though.💯
Amazing!
Wonderful educational video, love it!!!!

Isn't that what your ma does as well? Guess you can't teach a bad apple.
I have a three and a half year old daughter that is obsessed with the videos on your channel. She loves the music, your tone of voice, and all the video footage of nature. We often pause the videos to explain the things that you are saying, and she loves it all the more.
When she wants to watch one of your videos, she asks for " The nice nature science man".
Thank you for your amazing videos.
This has made my day and put a big smile on my face, thank you so much for sharing this with me. Say a big hello to your daughter from me! 😊 And thank you once again, this means the world.

@@bernardozuniga3662 his comment is gone and im afraid to ask but i gotta know what this guy said
@@FrostBitn he said something like "oh yeah a video with random facts thrown around with stock footage in the background, so impresive". Wierd response to the cute comment so im glad he deleted it
I've seen many nature documentaries through the course of my life and some of them are truly stunning. But never have I seen any documentary where such attention went into every detail - the titles, font choices, subtle design elements, infographics, edits, music, writing, narration... Everything is in balance. This is the boutique magazine of nature documentaries. Your passion is obvious and inspiring.
Your comment has made me unbelievably happy! I get a bit obsessively meticulous and ‘perfectionist’ when I make these films, which is why it can take me so long sometimes. So hearing that it pays off is just wonderful. I really really appreciate this, and I’m so glad you enjoyed!!
@@NaturalWorldFacts Take your time and just keep doing things your own way. You're making people happy.
I must agree, a marvel in every way
well said!
@@NaturalWorldFacts I'm in video production (not attached to this account) so I catch lots of random things people don't normally see and can be more critical. I have to say, the editing, narration and music combined is a beautiful dance of elements that bring on emotions of wonder and inspiration I haven't seen in a documentary like this. You should be incredibly proud of yourself, it's an incredible achievement. Something I can only dream of in my career. You're brilliant!
It's always a wonder to me how the photographers manage to get such amazing footage in such extreme environments.
Absolutely stunning isn’t it , like an alien planet
A lot of squids have been discovered by oil rigs.
Robots. Unmanned underwater robots with cameras are what almost every deep sea footage has been captured with.
I say almost because some has been captured by manned submersible crafts.
Using ROV
Robots..
I wish they would just give you a BBC earth camera crew and send you off around the world to do as you will 🙏🏻
That would be a dream come true!!! 😭
@@NaturalWorldFacts You deserve it man, and you’d do it justice. Maybe some day lol. Keep up the spectacular work. ✌🏼
I wonder if anybody has written to them suggesting that? I'm chronically ill and have a lot of paperwork ahead of me so I know that I may not get to it but I just wanted to mention the idea in case I couldn't. Ask patreon patrons if they would do it!
Is this a death threat
@@AlienAyleen 🤔
Glad I stumbled across this. A lot of CZcams “documentaries” are filled with misinformation and/or low production quality. This was beautiful in every way, and I look forward to watching many more.
Thank you, I really appreciate that!!
@@NaturalWorldFacts its just fascinating and i could just watch it all day
I totally agree regarding the misinformation communicated on many YT documentaries. The casualness of the presentation of incorrect information on these shows leads to misinformed people who then believe they are properly educated when they're not.
I'm a Science teacher with 40 yrs experience and it's a huge concern when people misinterpret Science and logic. Science is the foundation of how we progress and everyone should be very concerned about this ignorance of logic. What appears to be good videos leads to misunderstanding and over-simplification and this has become particularly evident regarding correct knowledge of the dynamics of Science leading to the pseudoscientific rubbish that many people readily accept today without questioning. Social media is largely responsible for this. This is particularly evident in understanding climate change, evolution and vaccination. When our leaders are also misinformed there is little hope for the masses they influence.
Hence why, one can make his part by watching all the add length, for maximum help :)
Bring back the dislike button so we can identify them. YT is pushing the misinformed forward
Hello! To anyone else also bewildered by the Greenland (sleeper) sharks' eyes, wondering if they're Just ~Like That~ bc of Deep Ocean Evolutionary Shenanigans, turns out that a lot of sleeper sharks have specific parasites (called Ommatokoita elongata) that latch onto their corneas and render them semi-blind. I suppose since the sharks don't prioritize vision for hunting, that the parasites struck gold.
Thank you! I was wondering what was going on there
@@ssprdyllc_lurkn Yeah, it literally looked like they had eyes made of spiders.
It’s gotta stink not having arms to pull bugs out of your eyes
@@Hym5225 Oh, don't get me started!!
@@KajiCarson "eyes made of spiders" Ugh - pure nightmare fuel, thanks so much! 😀
Sorry for the blurry shot towards the end of the film - I had some concerns about the legitimacy of some footage from a stock footage site in terms of its copyright allowances, so I have blurred the shot until I can officially look into it and obtain a license if necessary.
did you ever get this footage cleared?
One of my favorite topics about the ocean. Thank you Leo for making these amazing documentaries!
No worries at all, it was so much fun to make!!! Thanks for such a lovely comment

Sorry for the typo in the Greenland Shark length in the on-screen text! It should read 7m not 7cm - it was a formatting error from copying across my custom infographic text template. 😭
There's another in the text for the Giant Isopods at 28:00.
40cm to 15.7ft had me really shook for a momeny
I was looking for this comment!
@@Unicorn498 a 15ft long isopod sounds like a good idea for a horror film
Honestly I just saw it when the correction came up, it made me giggle. 7 cm is not that gigantic indeed ;)
I'm a psych provider who spends 8 hours a day listening to my patients talk about distressing topics. Although I love my job, I come home drained and sometimes feeling very emotional. Before I go to bed, I watch one of your videos and I feel my stress melting. Your soothing videos and calming graphics have helped me mentally enormously. I'm sure there are plenty others like me who just have not left you a comment yet. I hope you know how much your videos help and soothe us ❤️
I did a study on the humboldt squid once, their syntax is incredibly complex and beautiful! Their ability to communicate during feeding frenzies and stay coordinated is immaculate!!
Sure ya did.
What all went into the syntax? I believe that’s in the throat, correct? Or would I be thinking of something else?
@@corydinsmore1117 not everyone is American.
@@youtubegavemynameawaycuntbags or a petes.
truly incredible squid! Humboldt squid seem to play by their own rules! the feeding frenzies you mentioned, they are SAVAGE! and so calculated! I've always been fascinated with squid and octopuses, its a wild world they live in an some of the ways they operate are alienlike.
Yes!!! Your videos re-ignited my childhood love for marine biology. When you touched on deep sea gigantism before, it opened my mind to how incredibly nature can “copy” itself to sustain life.
It reminded me of how sunflowers are basically giant daisies… certain plants have leaf formations that are like the giant or mini versions of other plants, similar to how a mini version of a giant squid could be drifting far above his brethren, unknowingly.
Nature has this way of exponentially growing or shrinking its genetic material like that (not sure what the actual term would be lol just started the video heheh 🤣🤥) in a fractal-like manner that just blows me away. All to sustain life and keep it thriving in its environment.
TL;Dr These videos blow me away, thank you. ☺️
It's the Fibonacci sequence - a pattern in nature, the stars, even the human brain. The "code" of all that exists (in this universe at least). *Warning* once you start "the Golden Ratio" research, you are hooked for life, lol 😄
At least that's my experience ✌️
has nothing to do with the fibonacci sequence, thats just psuedoscience. (Literally a number sequence in which a term is the two previous terms added together, lol) biology tends to have recursive body plans because there are certain aspects that are pretty much objectively good for survival. What amazes me about biology is how organisms use different systems to achieve the same results, because it can often achieve different side effects and have a knock-on effect to other parts of the body. It’s so cool
@Repent and believe in Jesus Christ I have no use for your magic sky god - you do you and leave me out of your fevered fantasies
@@suzannea6452 but, I think this guy may have a magic torch that never goes out!! Says if we follow there will never be darkness, only light. Seems to me pretty obvious he has a never ending torch battery.
He's a saviour...meh...maybe not
@@suzannea6452 you don't need to be miserable ..
This documentary is absolutely stunning. I literally caught my mouth hanging open a few times. I loved your calm cool voice narrating the facts. The music choice was perfect. Emotional tones that sounded both fantasy and sci-fi. It almost romanticized these creatures. The writing too was gorgeous. I subscribed in the first ten minutes. Thank you so much for your work
Thank you so much Holly, this is so kind of you! Welcome to the channel 😁😁
You are very talented at making this type of documentary. I have PhD in biological subject, maybe that makes me picky when seeing documentaries and presentation of various evidence, yet this was surprisingly very very impressive. I also noted the great choice of font and details. Highest quality I've seen.
Thank you very much! I’m currently an undergrad student studying marine biology, so to hear my film appears high quality to yourself, with a PhD, is just wonderful!! I love making these films. It’s my dream to get into creating or presenting professional wildlife documentaries after graduating that don’t dumb down the scientific content, but still appeal to as wide an audience as possible and evoke a sense of wonder.
Wel your videos are already worthy of discovery channel or bbc. I don’t know how you do it but this is simply top quality stuff. Much respect! I am a freshwater microbiologist, and my research is involved in sediment and water biogeochemistry, metabolomics and biodegradation of pollutants. After watching your videos I feel that my understanding of aquatic biology increases. Also looking forward to view all the rest of the videos.
I refuse to believe that you aren’t on the same level as Blue Planet. These documentaries are incredibly beautiful and soothing. It calms my anxiety to listen to and I learn so much more. The way you explain everything is so clear, leaving no real questions unanswered. I agree with the other comment. You deserve to be airing on TV. This is incredible 💙
Your old video on deep sea gigantism was already fantastic, but this is quite possibly some of the best content I've ever seen! I love the addition of adding in parts of "Hidden World of Islands" and "Giants of the Polar Deep" (the latter being probably my favorite video of yours so far). The sheer size difference between the average sea spiders and their polar region counterparts is still pretty insane to me. Thank you for making these videos! You've definitely been a massive inspiration for me to continue wanting and trying to pursue a career in marine biology.
Fun fact, the magnapinna has just recently been found to use its tentacles aggresively, so it may be more predatory than previously believed.
If you're talking about that one specific clip, it's still up for debate on whether it was attacking, fleeing, getting lifted with the current from the vehicle, etc. I haven't seen any other evidence of aggression. I'm curious to know which source you're thinking of?
@@ElysetheEeveeI’m enamored by the fact that you know this specific clip off the top of your head
its cgi, wake up retard
Wow. I just want to say, I'm just another person here to admire your work. This video is so damn good it's hard to believe it's on CZcams. Such quality, just thank you for blessing the people with such videos. It's almost hard to put into words that anyone watching this truly can feel PASSION in your videos, it's like we can tell this is done by someone who just really really wants to put something marvelous in the world, just because they want it to be shared!
Take a moment to remember, every comment you read that makes you smile, makes your day, makes you happy- for every like that comment gets, someone else is saying it again and again! I know I've gone down the comments after watching your videos just so I can go like all the positive comments. You truly deserve the best!
You have no idea how happy it made me to read this, and to know you enjoy my films, and that you think my passion comes through. I started this channel when I was 9, 11 years ago, as a hobby, and to this day it remains first and foremost exactly that - a hobby!! It makes me so excited to get to share the wonders of wildlife with people who hold the same passion or have any amount of curiosity for the natural world. I never expected this level of love or this sort of a response, so seriously, thank you. You, and anybody who leaves supportive, warm comments, are the reasons I make these films and stay motivated. Have a truly wonderful day. You are an incredible person.
This had me feeling like I wanted to become a marine biologist for a minute, the quality of editing and the soundtrack and the content were all fantastic, I want to thank you for making this and sharing this with me, I really enjoyed it, thank you.
When that one marine expert childlishly said "So cool" aftrer seing a long squid, it was so wholesome. Seeing someone geeking about their passion always makes me happy
We’re all just big kids in the field of marine biology!! 😁
Imagine what kind of fossils are at the bottom of the ocean and how massive those creatures could have been, if there even are any fossils
The pressure eventually will literally crush the bones to dust. Ever seen a skeleton on the titanic ? Neither has anyone else ;-)
The way you curated this entire video (especially with the background ambient music) is noteworthy. I rarely pay full attention to most videos on CZcams, but yours simply took me on a journey ceaselessly.
Thank you.
That means a lot to me to hear that - thank you! The audio and visual curation is my favourite aspect of film-making, particularly with my deep sea series, so hearing it paid off is just wonderful!
I was checking out the channel and saw that he kept his old videos up when he was a little kid! I think it’s so cute and awesome that years later, he still has a love for animals. It’s amazing seeing how much he’s developed; makes me feel like a proud parent for some reason lolol
I found the polar gigantism extremely fascinating. Is there any more info on it?
Yes! I have a (now a little outdated) video on the topic, but a lot of that was re-done and incorporated into this film. I am, however, going to be collaborating with a scientific expedition cruise next year who are setting out soon to study the Antarctic sea floor and in particular the worms that live there, so stay tuned!! If you're interested in watching my slightly older Polar Gigantism film, here's the link :D czcams.com/video/Rw4WX2Dd8HA/video.html
@@NaturalWorldFacts thank you so much! I’ve spent the last day or so reading as many papers on it as I can. Hopefully might do a project for my marine science seminar on it. So interesting
It's so fitting that the biggest sea creatures are the ones yet to be fully understood. The very existence of deep-sea gigantism is so fascinating, it makes many myths about sea monsters possible because we just don't know what's down there. So, cool!
Everybody deep sea naturalist until Cthulhu fhtagn
There be nothing
ive been hyperfixated on marine biology and sealife since i was a kid, and finding this video makes me so overjoyed. i love watching these amazing creatures float in depths far from human intervention, allowed to live freely as they are. my favporite animal has always been a bigfin squid, so interesting and awesome
Keep it up, and we’ll have the ocean completely explored soon!
Ignoring the fact I dozed off halfway through from your relaxing voice, I’ve never been so encapsulated by a documentary before. This was so interesting and amazingly put together. Thank you for making this.
Thank you so so much! 🤭 I have a whole deep sea series of a similar style, if you’re interested in seeing more. czcams.com/play/PLKzq2xKdfIot0rJTxkzPG7srMQm0sSeIG.html
I study marine biology at uni and the deep sea is an obsession / fascination of mine!! So making these films is such a fun hobby.
One of the best nature documentaries I've seen in years. Thank you. Please never dumb it down for the masses
If I'm not mistaken, the Greenland shark has a problem with eye parasites. I think it's something like 60% of the sharks have them.
Yup! Ommatokoita elongata is the crustacean parasite you’re referring to - it’s fascinating.
Is that why the one shark's eyes were floating around in its head?
@@toothfairy430 The ones with the parasite look like they have two really long eyelashes poking out either side of the eyes
Apparently they’re not too bad as they act as a lure to prey.
@@toothfairy430 Yep. It's 14:50
I am in love with these documentaries, you do a phenomenal job! Although I have noticed a few of your conversions from centimeters to inches or feet have been wrong in a few different videos. The one I saw in this video is the Giant Isopod; you have 40 cm being 15.7 ft long, when in reality that is about 1.3 ft long. I just wanted to point this out to you in case it went unnoticed when you edited the video. Keep up the fantastic job, the algorithm seems to like you recently so I know all the hard work will pay off!
Thank you so so much for the lovely feedback, and for pointing out my error. 🙈 I have gone in and added a little on-screen card in the top right that should pop up with a correction at the relevant timestamps… but it doesn’t seem to be working quite as expected.
Anyway, thank you so much once again! I’m working on quite a few exciting films (in fact I’ll be releasing a trailer for my biggest ever project very soon) so comments like this really help keep me motivated. 😊
Holy cow! I have immense respect for you! You’ve been doing this for so long, and you have grown and your passion for life increases. My son is just like you. All his books are about animals and even though he’s young and in the spectrum he is so knowledgeable about nature. More than most people, including adults.
I stumbled into your channel and I’m so grateful! I’ve been binging your videos. They are so informative and interesting! Thank you
Every creature has a different constraining factor for its ‘common’ size. I’m glad you explored so many different aspects of how various constraints get lifted
absolutely stunning, your production quality has been constantly improving 😍 as always, especially love your music choices!! good luck with university and thank you for making these masterpieces🥰
Thank you so much Ellie!!! 😊 This means a lot to me!
Wow, amazing work. As an architect I took several screenshots of this video. Nature is so inspiring, and learning about the conditions due to which creatures evolved to be the way they are, certainly helps us with creation and perfecting our man-made crafts. And I feel so blessed to live in a time where I get to have access to all this information for free. People like you who put in the effort and passion need to be appreciated much more.
Also off-topic, but your voice is so soothing and hauntingly beautiful. Keep up the good work.
Just found your channel and I’m blown away?? Like your content is SO well made!!
I’m learning about this (biodiversity, evolution, and climate change) in college right now. I’m an environmental science major and I love seeing people like you make great content informing people how important EVERY part of the global environment is.
My focus is on the extinction of species and declining biodiversity in islands, it was so cool to hear you talk about them! They are so important!
Definitely gained a subscriber!
Oh thank you so so much for this, this comment has made my day!! I’m currently a student myself (marine bio at university) so being able to tie in and expand on concepts from my course is so much fun and absolutely fascinating!!
Your course sounds incredible, those are some truly interesting topics. Do you know what you’d like to go on to do after college, and beyond in terms of career?
@@NaturalWorldFacts I want to go into wildlife rehabilitation or something that works one on one with the wild animals
Keep making these videos they’re great!
Funny enough I'm covering the exact same topics in my current term at university! I just found this channel myself and these videos honestly feel a bit like a more entertaining version of my lectures as it covers similar topics lol :D
Isn't it phenomenal that we can get such a stunning video essay like this on youtube? For free??? I'm losing my mind. This is so much effort with the intention of spreading a passion and knowledge. I loved this video so much, thank you
Love watching these when I'm about to sleep. Such great topics with intriguing information, it definitely answers questions that I didn't even know I had. Amazing video, by the way, lovely work! :)
I just saw some of your oldest videos. It’s incredible to see how you’ve grown up your whole life so passionate and knowledgeable about deep sea/wildlife, and how incredible your videos have evolved. Truly amazing to see!
I’ve only just found your channel today, but I am already captivated by what you’re doing! Keep up the great work, I will definitely be watching more of your videos! The quality is top notch; visuals, audio, content, you’ve got it all! The effort does not go unnoticed!
I can’t believe these amazing creatures exist on our planet - the aliens aren’t in space - they’re in our ocean. Absolutely fascinating and we’re so lucky to have such hd videos. the ocean will never in our lifetime cease to amaze us.
I recently geeked out and made an enclosed terrarium in a giant cereal tupperware with my kids, there was room for tons of different rocks, wood, plants, worms and insects. They loved it but I think I had more fun than they did lol. I followed your instructions and its doing well so far. Thanks for the idea dude. 👍
This is actually insane that such high quality documentaries are available for free. Gosh I love the internet
I was in the mood for a documentary with this exact sort of tone what with the calm music, the soothing voice, etc. This was perfect, absolutely beautifully made and so fascinating to see. Love it
As ever, an exceptional presentation. I'd expect to find something like this on the BBC or equivalent organisation. Leo, you have an incredible talent and produce compelling content that is quite remarkable, especially given your age. Incredibly informative and wonderfully narrated, your channel is truly remarkable.
I often wonder how deep ocean pressures affect ocean pollution? Is it altered in any way?
Too often CZcams and other networks feel like a violent assault on the senses manipulating your emotions to hijack your attention and leave you mentally drained.
This video instead greets you with calm and gives you a half hour of exploration that stimulates curiosity and appreciation for the world with impeccable quality.
I am very pleased to have found this channel, excellent work.
I made my first CZcams account in 2005, almost 20 years ago now, and I still get amazed by how far it has come thanks to these amazing independent content creators.
I love how excited the scientists are catching the squid on camera
i rarely ever comment on stuff, but i gotta say this might be one of my newest favorite channels :) literally so informative and entertaining
What an insanely well put-together video! ❤ Your tone of voice and cadence coupled withe the music and the footage makes for a hypnotic viewing experience. Thanks for putting in the effort to make this masterpiece. I love seeing people share in their love and fascination for nature
The deep sea is both fascinating and terrifying. It´s like setting foot on an alien planet. The creatures look like they come directly out of a story by Lovecraft or a painting by Bosch. Amazing how life can thrive under such extreme conditions. But like "Ian Malcolm" said in "Jurassic Park": "Life will find a way."
Always happy to see a notification from you! It's great you're back to uploading. Deep sea gigantism has always fascinated me. Well.. deep sea anything fascinates me. Lol. Thank you for the upload.
yeah
This is so sweet of you, thank you :D I really hope you enjoy, it’s a topic that’s always fascinated me too so I really hope I’ve done it justice!
The big fin squid is one of my favorite animals probably. I love how mysterious, alien like, and showing pictures of it to people and seeing there reaction.
Your voice is poetry in itself. We can hear the care, the passion and the attention to details through it and it's fascinating. I ve watched your videos many times and i never get enough of them
I want to thank you for your incredibly well explained videos and how educative and entertaining they are. I always felt obsessed with the ocean, but I also held a fear towards it. Thanks to your videos I can feel myself more comfortable with visiting further more about the ocean. I initially grew interested about the deep ocean because of the cookie-cutter shark, my favorite parasitic lil fella. For my 2024 goals, I decided to watch your videos more often, and write down notes to get to know more about the deep ocean. I watched a few videos of yours with my dad, his native language isn't even english yet he understood how you explained it really well, he enjoyed it too. I also love the choice of music, it helps me concentrate a lot. Your videos have inspired me, and intrigued me more to study and learn more about the ocean. So huge thanks, and I'll be more than happy to continue my journey of getting to know the ocean life with your videos. Have a great day💓
I've always been amazed yet terrified about all the magnificent things the ocean has, I never thought I would watch a 30 minute long documentary about this. I really appreciate your great efforts into making these types of videos for people to learn. Keep doing such great videos, you gained a new subscriber. Greetings from Mexico.
I remembered the original gigantism video when I saw this, glad you decided to remake it. I can really see the effort and love put in. I also wanted to let you know I appreciate when you but the name of species in the corner in the shots that aren’t audibly explained. Thanks!
i usually have a hard time staying focused on a documentary because of my adhd, but your speech pattern and pacing of the video had me absolutely enchanted the whole time!
Started this video to challenge my thalassophobia. ended up crying at the beauty of mother nature creation
your videos have become some of my favorite on youtube, they are so comforting and informative, and you talk about so many interesting species, ecosystems, and phenomena surrounding the ocean that others do not. your video on cnidarians is my favorite, and if i feel sad i'll rewatch it and it will make me feel a lot better. thank you for these amazing, beautiful, and informative videos that you create.
this is so relaxing. i’m a herpetology student, but i love the deep sea and especially large squids. the footage of the bigfin squid from the oil rig always excites me- it’s like a scene from a found footage horror film.
It blows my mind, not just the animal facts but that this video is free on CZcams. Amazing production value and well put together. Thank you!
This narrator’s voice is so soothing and beautiful. I would usually listen to him for hours. One of the few best voices in the world! ❤😊
Thank you so so much, this means the world to me!
okay but watching the emotional and meaningful ending from an amazing documentary immediatelly switch to "your chance to win a Custom Tesla Model S-APEX-" broke me lmao
🤣😭 I’m fully aware of the irony, but I wouldn’t be able to afford uni or the video production without sponsors. I hope it wasn’t too intrusive or took away from anything - I reject brands if they’re opposed to a post-roll ad. But still, I’m sorry.
@@NaturalWorldFacts I dont think it ruined anything! the sponsor section was not only at the end of the video (not interrupting anything) but also cut really short, so it's pretty much as "un-annoying" as sponsors can get, was rather amusing than annoying👍
footage of the deep sea is a level of soothing i can't explain.
the troubles of the surface world seem silly when i think about how much is going on somewhere we can't even go in person
Can I just say that I LOVE the new graphics with the timelines that you've got in here? It's amazing and it really elevates your already amazing videos just that little bit. The fact that I can watch something this high quality for free on the internet is astounding- I love it so much!
not sure if it’s a british narrator, the background music, or just the clips of deep sea life, but (in an extremely positive way) this feels like something i’d see playing in a natural history museum theater. thank you for making this, it was very nice to watch on a rainy sunday afternoon
I don't regret refreshing my main page of CZcams, not gonna lie.
😁 I’m glad you’re here
I've always had a passion for astronomy, yet the ocean is always the thing that fascinates me most
I love your channel, Leo! This is some of the most amazing videos and documentaries I've seen. You have such a calming and comforting voice as well. You're like a young David Attenborough! Keep it up and looking forward to more videos. Cheers!
That shot in 15:59 was jaw droppingly stunning. One of the most beautiful images i have ever seen in my life.
Thank you for you deep sea videos, they remind me a lot of my childhood back when I was obsessed with the abyss, dinosaurs and space... I would've killed back then to see such good quality videos like this.
I am a life long lover of documentaries but I’m a stickler for quality. This was wonderful. And the music selection, so often neglected in documentary films, was exquisite. Bravo.
The cold temperature makes total sense. Look at people from the Norway, Sweden, German, Russia, mostly big and tall. People from hot regions, like Mexico, Southeast Asia, are all tiny.
The balls of the narrator to say there's no Lovecraftian creatures is insane have you ever heard of the bobbit worm that can grow up to 33 feet in length.
This was amazing to watch! It's nice to see a new video from you even though you are probably really busy. The polar deep section is an especially nice treat for me. But it is equally saddening how that is one of the ecosystems most affected by climate change. We hardly know anything about these incredible creatures and rob ourselves of the chances to study them. So thank you for showing them to a wider audience. If people were more aware of their existence, there would probably be a bigger effort for conservation. You are doing a good deed, my friend. :)
Just the intro to this doc alone is an 11/10. So glad that I found this series. Top notch!!
holy- the moment i heard you speak, i knew you would be the new youtuber i listen to as i fall asleep. your voice is so soothing.
Amazing audio quality, music, and visuals. I Would love to see you cover more natural world facts on things other than the ocean. Keep up the great work!:)
The Big Fin Squid is Just Cthulu trying to not Look Suspicious and failing at the task
This is one of the best videos I've ever seen
Beyond the extensive research, it's simply so well edited! With an amazing atmosphere kept throughout with a perfect use of music.
I love this
Amazing video ! I was searching for informations on how the environnement of species could module their size, and then I stumbled across your video that really helped understanding the phenomenon of insular and deep-sea gigantism. Thanks !
Thank you for another beautiful and informative production. Your videos are made with so much skill, effort and passion and they're an absolute joy to experience. Thank you also for introducing your viewers to fantastic and lesser known musicians, in the tracks you use. I've always been creeped out by marine life in the way that other people are by spiders, but your content has really helped me to appreciate the diversity of these lifeforms in spite of that gut feeling.
Thank you for talking about the sleeper sharks!! And for telling the correct years of that damn green lantern study! My absolute fav sharks are the six gills, such strange, puppy-faced giants.
This was a really lovely video!! Major props man!!
I love this documentary. I started rewatching it the moment it ended.
No way! Thank you so so much! 🤭
I do research and alot of my time is spent shifting through data in front of a computer. I love listening to these videos and glancing at the visuals as I work. I also love the music you add to the background and have added a few songs! You should consider a playlist of the music you use, I would absolutely follow it
mans just made a whole documentary
I have to say, I've been following your channel for over a year now, and every time your videos never fail to enthrall and fascinate me. Each one has improved always consistently and now, with these recent 30+ min videos, your channel is legitimately reaching proper documentary level and quality. I am truly impressed with the production value of your videos and support full on this longer length format, even if it means waiting longer, please continue to do so!
These go so in depth and I appreciate the research and you leaving where you have cited everything. Your website is something really interesting and I like flipping through it and your writing. I’m going to get your t shirts for myself and my partner. I hope both sides of your pillows are cold. I LOVE your work and I’m eagerly waiting for another really long video to watch a quadrillion times!!
Dude's got most soothing voice ever. I love deep sea videos, so having this amazing video combined with the voice is just *chef's kiss*
I recommend your videos to anyone who will listen. You’re out here making the content we crave. I appreciate your hard work and dedication. This is a craft that you’ve clearly mastered. Thank you. 😊
At 28:00 I'm quite surprised by the Giant Isopod's relatively diminutive metric sized compared to their truly gargantuan Imperial cousins. Those things get 10 times larger than I would've thought! Excellent video as usual.
Same with the imposing 7cm greenland shark
😭😭😭 Ugh I should’ve got more sleep before attempting conversions
@@NaturalWorldFacts I wouldn't worry about it too much, the overall quality is otherwise top notch, I love these documentaries you do!
@@Isaac_howell Thanks Isaac, I really appreciate that!
@@NaturalWorldFacts Our ability to joke about the mistake means that no actual information was misinterpreted. Merely a tiny slip up in presentation.
Have been looking for literally any good channels for nature documentaries / video essays and you’ve been a total happy surprise to say the very least. So beautiful and well-done
I am so glad this came across my recommendations. Beautifully done, one of if not the best film on deep sea gigantism i have seen
As someone who is very interested in deep sea life. I have to say. This..... this was amazing and inspiring to watch!!!! Insane work, my respect!
Liked and subscribed!
Thank you for having captions!!! There’s so many documentaries on this platform that do NOT include them, they are hugely appreciated!!!
These videos are GREAT. I particularly appreciate delivering facts without having to create a narrative or sentimental story and drama behind the natural world and its inhabitants. It's hard to find documentaries that don't do that. One slight criticism I'd have is the insertion of text while the narrator is still talking, that makes it difficult to follow both (at least for a non-native English speaker like me), specially if the text is more than 2 lines long and when they disappear so quickly. Maybe insert the text in the pauses and/or leave them on the screen for longer.
I sat down to fall asleep and found your video on whale falls by accident. "Perfect" i thought, "something nice and boring with a soothing narrator to fall asleep to." Then i got invested and had to know more. 3 videos later i now know more about deep sea creatures than i ever have in my entire life, and yet am not asleep lol thanks bro, i love it
An absolutely amazing and jaw-dropping documentary. Makes me realise how much more to the world there is than I ever thought. Thank you for these videos.
