- Cephalopods exhibit some incredible features. Out of all 8,000 living species of marine invertebrates in the oceans, by far the largest, most deadly and most intelligent are the cephalopods. A class of highly developed mollusks that includes octopuses, squid, cuttlefish and the mysterious nautilus. Their graceful fluid movements, vibrant colour changes and complex brains make them one of the most peculiar and important groups of organisms in our oceans. The largest - the giant squid - measures longer than a school bus, while the smallest could sit atop your finger. Let’s take a closer look at these diverse and often alien-looking invertebrates.

LMAOOOO
I know. Hate dumb selfish humans. Vegan here.
Because they taste delicious and have a lot of nutrients 🙃🙃🙃
I had a pet octopus that i found in a small puddle on a rocky beach. He was maybe 5 cm in size when i got him and have kept him for over a year in my aquarium. James (his name) was a very smart dude, he knew i went out every afternoon to catch crab for him because he would always be waiting in the front corner of the tank where i would drop the crab when i got back. He got rather big and i set him free when he was about 3 kilos. He liked to be handled and would hang out on my arm whenever i put it in the tank.
Such beautiful and highly intelligent creatures!
When I worked at a tropical fish warehouse the octopus was by far my favorite resident.
A while back I found an octopus in a rock pool as well. I remember just traversing the massive rocks that were apart of the beach area that met the sea and all of a sudden a huge splash occurred in what seemed like a fairly calm collection of rock pools.
Then I noticed a floating fish head in the pool and right after I saw it, he was camouflaging against the rock about a metre away from me. I called my family over to have a look and he got spooked and slipped underneath the rock. My step father in an attempt to lure him out tried to use his sunglasses as bait and the octopus actually grabbed onto them and was having a tug of war with my step father. Despite the creature only being maybe the size of a dinner plate his suckers had a really firm grip on it. It was really interesting.
@@eternalblue4660 It is sad that such a smart and fascinating creature must be so short-lived.
@@jeffthompson9622 Agreed, they always seem inquisitive when you watch footage of them. You can tell there is something more going on behind the eyes.
This is so high quality and it is so charming that this is an independent production.
Thank you so much!! It’s been a passion project of mine for about 10 years, and I’m off to Uni this year to finally study Marine Biology! I can’t wait to make more of these :)
I agree very high quality but I'd like to point out that anything on youtube could be considered independent production
@@d3athreaper100 most nature shows are usually made by big companies, this one is just this dude
I think that's what he's going for
@@lackofha1992
Ok but at 9:56......OUR deep sea hub.
I'm pretty sure there's a research team an editor and a whole team of people who deserve credit
@@NaturalWorldFacts omg this makes me so happy !! hope you do well and to more success in your career!
This footage is BBC/Attenborough quality. Incredible...
Raw footage creds go out to the brilliant scientists at OceanX, Schmidt, EVNautilus and MBARI :)
Check out their stuff, they post full ROV dive footage for people to watch and use like I do!
@@NaturalWorldFacts excellent video!! Do you have permission to use these videos on your channel?
This channel really deserves so much more attention than it gets, the production value and information in these videos is absolutely fantastic. Where do you get such incredible footage?
Thank you so much Jake! That means a lot :)
The footage is from a number of sources, but the main ones (and most unique) are MBARI, EVNautilus and OceanX. These companies are at the forefront of deep sea research, sending down high-tech robots and ROVs to the otherworldly depths in pursuit of new discoveries! Working with their raw footage and being able to turn it into these films, presenting their findings and research, it’s such a fascinating thing and I love that people are engaging with it so much :)
@@NaturalWorldFacts that's truly amazing 😮
Bold and brash
6:43 can you imagine what might have gone through the mind of the person that first discovered this creature
Looks like H.P. lovecraft shit.
fr, I got chills down the spine that was scary, I almost shit my pants
@@superfluous9726 It looks like a scay tall pale skinny ghost squid
"LOVECRAFT WAS RIGHT!! HOW DID HE KNOW?"
“UH EXCUSSSSSSEEEE MMMMEEEE???!!! WHAT IS THA-“ *weaponised terror and disorderly behaviour with confused screaming*
One reason why cephalopods are frequently depicted in the media as monstrous and menacing is because of their tentacled appearance, even though real life cephalopods would be passive when encountered in the ocean.
🐙 are fairly docile but I've heard most squids are predatory like Humboldt or some squid in the sea of Cortez won't tear you apart but they will definitely try seeing if they can take you
@Squ¡¡d 🐦 🐈 and 🦑🐙 are my favorite animals ❤ 👌
Sometimes they stick to people but I think it’s out of curiosity. It will be grim to think they do it for fun
I just went snorkeling in the Bahamas and saw two squids! They were just chillin! I swam close-ish to then (I wanted to give them their space) and it was super cool! They were just as curious about me as I was about them, truly fascinating creatures! 🦑
I feel like most animals are this way because being a monstrous, hyper aggressive animal would be a pretty bad survival strategy. Most animals run away from us or leave us alone, unless very specific situations where their survival is threatened. Except Moose. Moose are fucking diabolical xD
Whenever I see a giant squid I get chills down my spine. The fact that something that large exists is terrifying yet beautiful in a strange way. I do however wish you went more in depth about the lesser known cephalopods like cuttlefish and nautilus, those things are just so interesting and diverse and I’d love to see what you have to say about them!
Are nautilus really that interesting though? I have such deep love for & fascination with cephalopods I just can't get enough of them, but I've never really considered nautilus in the same category as octopus, cuttlefish and squid. They seem so primitive, so primordial, they really don't seem to have evolved to any level of complexity even approaching the other cephalopods. I could be wrong, that's just my impression of them, but to me they seem like the cephalopod equivalent of goldfish. I've loved aquarium fish since I was 10 years old, especially the genus/species with more complex behaviour, but goldfish are boring AF. They literally just swim around and eat whatever they can fit in their mouths. Do nautilus do much more than that?
@@lachlanbell8390 It is true...but the fact it has barely evolved means it's already perfect for its environment! I'd love to know how it actually has been so successful. Just throwing my two cent's out there :3
@@sayosweeti5757 are you a girl?
@@TheGrayton2000 yes i am! I’m just very into cephalopods :))
Yeah, I get chills too, but for a different reason. Imagine being in the water with that giant clever bastard. I'd probably have a heart attack and die before getting eaten lol
I never comment on TH-cam videos but I need to this time. The quality on these videos is amazing. The combination of images, background music and narration is very well done. Sometimes the content or the length of the videos may not appeal to everyone or attract millions of views (yet) but the work done here is phenomenal and you deserve a lot of attention. Great work!
Thank you so much!!! That’s so lovely to hear, I’m feeling really motivated thanks to you :)
Making these films is so much fun and I’m not planning on stopping anytime soon! I can’t wait to share more and hear what you think. Drop me a comment anytime and I’ll be sure to respond, welcome to the channel 🦑
Man, this reminds me of why I wanted to be a marine biologist as a kid. Great production value on your videos, my dude! A small, but noticeable thing, is the appropriately-chosen music in these; the mysterious creatures have mysterious music backing their appearances, & it’s a subtle but meaningful thing that really reflects the feeling of living underwater...it’s such an alien concept, fascinating and frightening in equal measure to myself. Great work on your videos!
You’re spreading knowledge freely about our natural world. With such great production. God bless you and your endeavors.
Thank you so much Tubb 😊
I love your voice. It's so calming.
Thanks :)
I looked it up, and turns out that this channel and the Deep Sea Hub are made by the same person. Cool work!
Thanks so much! Did you find me through this channel or through the hub? I adore the deep sea and am so pleased people are enjoying my projects 😊
@@NaturalWorldFacts Hi! I found you through this channel
Glad you found me :D Drop me a comment anytime, I’ll see you around
@@NaturalWorldFacts Deep sea is where it's at mate!
This is by far the most addicting TH-cam channel I’ve ever watched!……hands down.
This channel is going places. From the production levels, to the information and it's delivery, all expert quality in my layperson opinion. Wouldn't feel out of place on the BBC. Keep up the amazing work, you've found a fan in me.
Thank you, that’s really really lovely to read!
Oh finally a cephalopods video!! Those are the absolute best marine invertebrates :D
Best part was about cephalopod bioluminescence and gigantism, especially because those are the most poorly known, mysterious aspects when it comes to fossil squids.
It's also brilliant that you're putting the music in the description :)
This channel's gonna blow up, I can feel it.
Thank you so much Christian!! This was one of my favourites to make by far - getting to show off the diversity of these creatures from the shallows to the depths. Those with gigantism truly blow my mind - the size of these things, it’s incredible how they come to be that size.
Thanks for the support 😁 I’ve had a huge boost in motivation these last few months and its thanks to you and Alex!
@@NaturalWorldFacts tripp
I stive to learn about marine biology, so this is amazing! It actually feels like a national geographic documentation! You've done an amazing job
Woah thank you so much!! You’ve made my day
Same and I see u also play splatoon
@@Mariana_Manta u play to?
@@Vicsm3ds0807 yeah it’s one of my favorite games

I just discovered your channel this past week when I was looking for documentaries on the ocean zones for a project. Your documentary Into the Abyss was amazing and I’ve been watching the rest of your videos whenever I can. Absolutely love and adore your content! Sending lots of support from Texas!
Thank you so much, that’s so lovely of you to say. Making these videos is so much fun in itself, but knowing there are people out there who enjoy watching them is just incredible. I have many more yet to come, and I just can’t wait to share them :)
I hope your ocean zones project went really well!
The only issue i find with your videos is . . .
They end too soon !
Thank you !
👍😉
Thanks so much!! You can certainly come here again 🥰😌☺️
@@NaturalWorldFacts Super cool video! This is the first time I watch your channel and it immediately got my sub
Glad I found this channel at 2 AM. Squids are so weird and interesting, love em. Fantastic production value!
You should start a podcast or make some longer videos. This is so interesting and your voice is oddly calming
This is the 3rd video on this channel I've seen so far and the production quality and research is astounding! This kind of thing is something National Geographic would take 7 years to make and then only release to those that can afford it, but here you are knocking out mini segments for free!
I don't know why but I've always been interested in cephalopods in general and when I first saw the Magnapina Squid I just thought about how amazing and unique every deep sea creature is.
Absolutely riveting material!
I'm a very happy subscriber sir!
Your friend from Canada!!
Thanks man. You’re starting to sound like a true brit with that eloquence! Maybe my narration is rubbing off on you 😉
Jokes aside, really glad you enjoyed the vid again.
Your friend from the United Kingdom of Great Britain and Northern Ireland!
Man, the oceans are still majestic and mysterious, and to think we still don't know so much about them and their residents. Great video :)
These creatures are so uniquely interesting, beautiful, and intelligent... we are truly blessed to live during a time where deep sea explorations like these are possible 😍
these videos are so calming to watch, not the mention the high quality and the availability of captions
you deserve waaay more subs
This was such a pleasure to watch, all the clips and all the editing was incredible! I never had a particular interest in the deep sea but I sure do now, instantly subscribed!
Thanks Amy 😊 that means a lot, welcome to the channel!!
I want to thank you guys. There are not enough words to convey my gratitude for the videos you produce. I have a 4-year old and probable 'aspie' who devours them with such side eyed wonder. Our second home is the acquarium, but this is by far the next stop to scratch that itch. David Attenborough is a legend in his work, but the amount of detail and labelling you include makes you the ultimate in our eyes. She dreams of deep sea research and has a particular interest in cephalopods, tardigrade and other extremophiles, I believe they are called? Anyway, you're wonderfully curated images and information inspires and brings her endless joy, so thank you, thank you, thank you!
i saw this vid in my recomendations and i got super excited! i love cephalopods and i immediately clicked on! your voice is so calming and the production feels like something out of a nat geo documentary! i cant wait to watch your other vids!!
I want to be a marine biologist but everywhere I look there's almost no resources to start studying. These videos are so interesting and I love your channel!!!
I wanted to be an Oceanographer for 10 YEARS lol it was my passion for the entirety of my childhood & my answer whenever anyone asked me what I wanted to be when I grew. When I got closer to graduating my parents discouraged tf out of it by saying the pay was terrible & the jobs were scarce where we lived. This is so fascinating. Mine boggling you don’t have more subscribers.
this channel is underrated. you make me feel like i am watching a documentary, so professional and amazing
These creatures have fascinated me since I was a child, thank you and well done.
Truly amazing quality. This kind of video is the jewel on TH-cam's crown
This is awesome! The shots of all the cephalopods are so beautiful! Truly, some of the greatest creatures.
You have a soothing voice and made a carefully-detailed documentary about a sea creature I find to be the second most interesting one there is in the deep blue sea, right after jellyfish. Thank you for making this. It's very educational and straight to the point. :)
I'm completely in love with your videos and narration. It's a travesty of immense proportions that you don't have more subscribers. Amazing work!
Aw that’s so sweet, thank you so much
Impressed! Going through your content. This is one of my favorite videos on youtube now. Completely blew my mind. This will be forever stuck in my memory. Thank you.
I've really been enjoying your content.
Thank you for taking the time to create these videos.
We need more people like you and fewer Kardashian types.
they are amazing! it's honestly hard to believe a creature like that exists on earth! now i know why they're my favourite animals.
I am truly grateful I found your Chanel, I am a really big natural sciences geek..lol
Also, your soothing voice helps me fall asleep when bob ross can’t
The plural of squid is squids when talking about multiple species, i.e. one giant squid, many giant squid, many giant and colossal squids
the more you know
You must be squidding? Oh no, you are serious
@@Dogsineed he was for eel.
I was dissapointed that a group of squid isnt called a squad
@@alifandaniakbars.ip.3693 SQUID SQUAD!!
Just found this channel, and I honestly adore it! Your voice is so calming, and even though I like understand almost nothing its interesting to watch LMAO. Amazing work! :D
I'm so glad I found this channel. It soothes the soul...
Aw thank you :)
I just recently discovered this channel thanks to the algorithm and I've been binge watching your videos since last night. 💛💙💛💙
Me, seeing any deep-sea creature: it's just floats there... menacingly!
I love these videos with the chapters, the extra work is well worth it 👌👌
What always blows my mind... is when you consider that; at every moment, of every day (including right this very second) there are creatures like this, as well as creatures of all different sizes, just...swimming, eating, fighting, mating, EXISTING in the pitch black world of the super deep ocean. They withstand pressures that would kill US in a nano-second if we were to suddenly be exposed to them, and temperatures just a hair above freezing..
So remember....; "Every moment, of every day. Including right this very second". :)
Thanks for these videos NWF. This is a topic that I find truly fascinating.
Always a mind-boggling thing to ponder! It’s such a mysterious and beautiful world down there.
I've been on a binge of your channel, you make such informative and interesting videos! The quality is amazing. I'm happy that you get to do what you love :), hope school goes well for you!
I’ve watched a bunch of these tonight and man I can’t get over the editing and music! So well done
That’s so good to hear, thank you so much!!
As a marine biology student myself your videos are very helpful! keep it up man🙂
Such a calming voice makes it even more fascinating. Giving NatGeo a run for their money
Thanks 😁
I'm binging all your videos. It's so good from quality to the way the information is delivered and how informative it is.
Your videos are incredible. I can’t believe I didn’t know about your channel sooner!
This is so relaxing to watch and listen to. It's also so informative and interesting and keeps me wanting to watch and learn more and I have thalassophobia!
Thank you so much!!! Your feedback made me smile, I really hope you enjoy the rest too 😊
im only just now discovering your channel and it really is such a wonder to see
im slowly falling in love with deep sea animals because of your videos
Aww thank you, thats so lovely- the deep sea sure is fascinating! It evokes a mingled sense of fear and wonder that’s so unique
I believe that this is the most educational, beautiful and life affirming site !
The most amazing channel I’ve seen in years. Subscribed.
Congrats mate. Truly good job on the production of this video and your follow ups.
This is an amazing project/production. This needs more love, attention and views. This needs to continue to grow for more amazing videos of our astonishing planet and the creatures and ecosystem within it. Keep up the great work guys!
Thank you so much!! It’s just me making these by the way, though sometimes I feel like I could do with a team 😅
Well I believe with continual growth of the channel, I'm sure you can definitely find some people to become a part of this team.
Make sure they're people who are just as passionate about it as you are and won't settled for less and continue to press on in the discovery of the unknown and even just more coverage on the known as well.
Also, is it you who is going down and getting this footage? If so, that is miraculous! I envy you, being able to see all of this wondrous beautiful and mysterious life below us.
Just watched this vid with pleasure. I subscribed right away. I'm a scuba diver so I've seen some crazy stuff on night dives. The thing that really struck me was that these amazing, wonderful, beautiful and on and on...only live for 5 years TOPS. That's a lot of stuff to figure out in just a few years. My husband, daughter and myself went to Mexico where the water is only knew high when the tide was out. My daughter found a cool shell that she hung onto for a keepsake. She had the shell in her hand (she was about 7 years old) and what crawls out...yep a really small and gorgeous octopus!!! It crawled out on her hand and let her hold it and watch it for a few minutes or so. What a perfect time to explain to her about octopus and how they were just SO cool.
Love falling in sleep when listening to this nice friendly voice.
I'm with the people who are congratulating you for the outstanding presentations...You have a new subscriber.
Thanks for quality and professional attention to keeping the narrative easy to understand..
Bravo!!!

i love your videos so much. i have a huge fear of oceans but these videos help. i dont think ill ever be able to go into the ocean but knowing more helps me be able to think and talk about it more
hey i just wanna say that i've been following you for a few days now & i look so forward to watching your videos. i've binged watch hours of them & i love them. ive learned so much. the music & videos are always made in such a unison that it makes them hypnotizing. from what i've seen in your other videos descriptions, links, & replies that you make to people; you put so much effort & love into your content that it's invigorating. thank you for these; & i can't wait to see you glow man. ik other people comment how awesome you are & i hope you know that everything of what people are saying is true about you man, you've earned all the praise that you've received:)
You’ve put a huge smile on my face with this comment, thank you so so much for taking the time to write such kind words about me and the channel. It’s genuinely motivating to hear that you enjoy the films, and to know there are people out there who love learning about the natural world as much as I do! The whole process, from finding music I love, to writing scripts and editing stunning footage taken by deep-diving ROVs, is just so enjoyable, and I’m so so pleased to hear you find them hypnotising and binge-worthy :) Making these films has been a huge part of my life for the past 8 years, and I have absolutely no intention of stopping any time soon! I can’t wait to share more films and hear your thoughts - it makes it all worthwhile. Also, it goes without saying but welcome to the channel my friend! Drop me a comment any time and I’ll be certain to respond. Stay inquisitive :)
I really like your calm nice voice!
