The mysterious cephalopods. Here’s something for all you deep sea nerds/aficionados. Facts that I can’t even pronounce. 1. cephalopod /ˈsɛfələpɒd/ is any member of the molluscan class Cephalopoda (comes from Greek, kephalópodes; "head-feet") such as a squid, octopus, cuttlefish, or nautilus. Fishermen sometimes call cephalopods "inkfish," referring to their ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology. There are over 800 species of cephalopods and marine biologists keep finding new ones. 2. Cephalopods are found in oceans all around the world. None of them can survive in freshwater, but the brief squid, Lolliguncula brevis, found in Chesapeake Bay, is a notable partial exception in that it tolerates brackish water. Cephalopods are thought to be unable to live in freshwater due to multiple biochemical constraints, and in their 400+ million year existence have never ventured into fully freshwater habitats. (400+ million years. That’s impressive) 3. Cephalopods are found in all levels of the ocean, from the abyssal plain to the sea surface. Their diversity is greatest near the equator and decreases towards the poles. 4. Cephalopods are widely regarded as the most intelligent of the invertebrates, and have well developed senses and large brains. 5. Captive cephalopods have also been known to climb out of their aquaria, maneuver a distance of the lab floor, enter another aquarium to feed on the crabs, and return to their own aquarium (so maybe not a good idea to have other pets incase your squid develops a taste for cats or dogs) 6. Many cephalopods are social creatures; when isolated from their own kind, some species have been observed socializing with fish. 7. They have good vision but are color blind. Strange considering they can change colors ie camouflage. 8. They propel themselves through the water but some octopus species can walk along the seabed. 9. The Kraken are legendary sea monsters of giant proportions said to dwell off the coasts of Norway and Greenland, usually portrayed in art as giant cephalopods attacking ships. Yeah, we all remember the Kraken in Pirates of the Caribbean franchise and that weird squid 🦑 face pirate. He was creepy. 10. Since it has numerous arms emanating from a common center, the octopus is often used as a symbol for a powerful and manipulative organization, usually in a negative context. Hey, even James Bond encountered Octopussy. 11. Hawaiian creation myth says that the present cosmos is the last of a series which arose in stages from the ruins of the previous universe. In this account, the octopus is the lone survivor of the previous, alien universe. Now that is a cool final fact. Enjoy all you deep sea lovers! available WW except GAS

Octopuses are my favorite creatures. They are insanely intelligent, graceful, beautiful and unlike anything on this planet. It pains me that their life span is so short. My one wish is to be able to interact with one before I die. Watching the divers interact with them was heart-warming and emotional for me. This truly was a beautifully executed documentary, one I will revisit many times. Thank you for this.

This was excellent! We really need to honor the people who do this often dangerous but quite educational work. Thank you to everyone involved.

If we ventured to another planet, and didn’t know what an octopus was, we would absolutely say “we found an alien!” It’s so amazing to see interactions with the divers...

The deep sea is like the deep space. Infinitely mysterious and interesting.

I've been obsessed and in love with octopi since I was a kid. Other kids thought i was weird because my favorite animal was an octopus, but they're just so sweet and intelligent. Seeing their playful interactions with divers makes my heart so happy. They're just so cute!

You really shouldn’t film these fish without their written consent.

Lately I’m addicted to this type of documentaries lol idk

The deep ocean is as eerie and mysterious as the deep space!

10/10 my kitten loves this documentary thank you so much

I got to know some local wolf fish and When we dive this spot where I live which is on Vancouver Island we would bang gently on or tanks and 9/10 times the Wolf fish would swim out of their hiding spots and meet up with us and wrap around us inviting us to rub and pet them as we swim to what they like us for which is feeding them spiny sea urchin ... It’s a strange feeling to be diving and have a big 7-8 foot wolf fish wrap around you like a constrictor snake but without the crushing death ;) they are super gentle... Great video !

Fantastic photography. That sequence with the marlins feeding was wild and very rare to see.

That was amazing watching Octopus how they communicate with people

If you try and imagine what an alien would look like, these guys are fascinating, their features are almost unreal.

Marine Biology is a field of constant discovery, the biodiversity is almost immeasurable, just wonderful to watch and learn 🙂 Another great upload from this marvellous channel. Thanks! ✌🏻

Dear Free Documentary, As always, I love you

Beautiful documentary. All are absolutely amazing creatures. Giant squid have been historically feared by man, as in the legend of the Kraken. But seriously, they are so intelligent and octopi have been known to escape from their tanks. Also, it's amazing that the water pressure of the deep keeps the colossal squid intact, and once at the surface, they fall apart, due to little to no pressure. I am waiting for the day when real video footage of a fight between a sperm whale and a squid is released. I really hope we can get something in my lifetime.

BEAUTIFUL, GRACEFUL!!!! and incredible. Thank you for the post!!!.

The divers & scientists & camerapeople are brave so BRAVE!! If it werent for their interests & documentation we wouldnt appreciate so much because of what we have learned through generations. In Aww all I can do is appreciate say Thank you. Thank You!!

Other octopusses: Where have you been? We haven't seen you for awhile. Tagged octopus: You'll never believe it. I was captured by aliens, taken up out of the world and into a terrible place that had no water. Then the aliens did all kind of weird things to me. I was finally able to escape but I'm still kind of shook up. Other octopusses: Suuuure. Aliens above the world. Tagged octopus: But it really happened I tell you. The aliens only had 4 tentacles and they never seemed to use 2 of them. Other octopusses: You were just dreaming. We all have visions when we dream. Luckily your nightmare could never come true.

Quality upload 👌

Superb documentary never thought I’d end up loving and respecting Octupi that used to terrify me. The baby leaving fro their care was so full of feeling.

thank you for showing that there are still a few humans who can appreciate the magnificent creatures we share this planet with xx

41:48 Octopus returns to tell alien abduction stories that no one will believe.

Wait a second, is it not “octopi”? I’ve gone 26 years thinking “octopuses” was incorrect. This documentary is more informative than I expected.

The narrators voice is so nice and soothing. I love these documentaries.

By far one of the best documentaries I've ever seen.....thank you!!

Fun fact: the way seals and sea lions move on land is called galumphing. Yes, galumph is the actual scientific term.

Absolutely magnificent! Utterly mindblowing! Perfect setting...Paul Bendelow is such a wonderful and serene narrator! These creatures capabilities are indescribable! Thnx for this unique and splendid film!🦑🐙

Absolutely staggering. Thankyou for sharing these amazing creatures with the rest of us mere mortals.

Very informative, enjoyed this alot.

Animal documentaries always relax me and put me to sleep 🥰 I love learning.

Absolutely amazing documentary. Much props to the divers.

Manta Rays are such beautiful creatures, they seem to fly under water and I never tire of looking at them. 😁 Cheers

Amazing! This doc was an emotional rollercoaster lol. I was happy, sad, scared, shocked! Just amazing. The interactions were flawless! Keep up the good work👍❤

Watched full video without skipping. Very nice. Good effort from the team.. 👍👍

Thanks for an excellent documentary. love these amazing creatures.They really seem like aliens!!!

I find it heartbreaking when I see squid’s and octopi caught in nets. To me they are almost sentient beings. They have such a huge intelligence.

These nature documentaries are highly relaxing for me so whilst trying to Learn from them fall asleep when sat peacefully in my chair so thank you for the hours and professionalism put in to create these films i

When I’m really stressed out or not feeling well, I curl up on the couch with my pillow and a blanket and watch these.

It's 4 am and I'm watching a documentary about octopi. Fun.

I came here for the cephalopods and ended up learning about a hundred other things as well 👍

dolphins: Yayyy this is fun! Everyone else: What am I going to eat Jellies: *rave music*

When I was in elementary school, I had a summer marine biology education course. I learned by watching the staff interact with the residents(marine animals), that octopuses are as smart as a dog. They remember faces and the way people treat them. I don't think cephalopods are from this planet, or they are the ancestral precursors to modern human ingenuity. They have personalities and likes, just like people. An octopus mom, is dedicated until death... But at least in an aquarium she can see her young develop.❤

I did no expect this documentary to be as good as it was. Really interesting and easy to watch

Wait. The Humboldt only comes to the surface during full moons? That almost seems ominous.

Thank you so much for sharing!😍😍🥰

Omfg the footage had me in awe the whole time! They way that white tip shark scanned the diver with his eyes up and down was spectacular to witness. Great content!!

Extraordinary creatures! Thank you for the beautiful work ❤

I wish there were more videos about jellyfish,octopus and squid.

Enjoyed this documentary on Octopus 🐙 & Squids 🦑 very much, very informative and the divers provided dynamite footage 🎥

Great to unwind before going to sleep.

This is a great documentary. Equality educational and intriguing. I hope we can protect these beautiful ecosystems.

For anyone who hasn’t yet, but loved this doc, be sure to watch “My Octopus Teacher!”…✌🏼🇨🇦

Fantastic work on this documentary! I always enjoy educating myself through personal research and by watching programs like this. It’s much appreciated. Also, is no one talking about this terrifying-looking squid at around 5:16? I mean, don’t get me wrong; it’s a beautiful animal, but it’s enough to give me nightmares.

I love playing these in the background while I play/study

Very interesting and enlightening, thank you for the good works also feeding the sea animals with the salmon scraps is so cool.🙏🏾🙏🏾

Nice documentary. I really enjoyed it.

thank you for these uploads!

13:50, the shark had a huge gash next to the gills and the other 2 looked like they were protecting/comforting them ❤️

Sorry to see you go through that Nick! We all know that you do an amazing amount of work to keep your critters well!

Wow what a beautiful and full of knowledge documentary...🤗😍 Thank you for all your efforts for making this possible.👏👍👏👏👏 Keep it up and be safe.

It is always so funny to me that when scientists pet any animal they always seem to like it.

I like how you always give the camera people a mention by name in your films 😊

Fantastic documentary, very interesting

these are fantastic videos! thanks for sharing the information and the awesome footage.

I love this documentary

Thank. you for,this wonderful film 💖

Great Nature film.💚👍😎

My stress free reliever. I enjoyed much

If I was a treasure hunter I would take pics of gold and silver coins, and shipwrecks, etc, on my dives and show the pics to every octopus I came across to see if they would catch on and lead you to anything familiar they saw in the pictures if there was anything like that sunk in the area. I mean is that not unreasonable to think they are intelligent enough to understand what you are "asking"?

Amazing, watched and enjoyed ever second.

Incredible Beautiful, I ve got tears in my eyes. Thank you for sharing this beautiful World ❣️😍

I injoy watching the species

So like an alien abduction for us? (Octopus taken out of water .. tagged and weighed.)

Beautiful video👍👍👏🏻👏🏻👏🏻

A number of years ago i was diving with a octopus in Quathiaski cove that was about 18 ft from tip to tip !! Amazing friendly octopus!

Awesome video guys. I love learning new things.

Thank you for these great images! On your next film PLEASE let us know how large the various sea creatures are. They all look BIG when filmed from close by... 😜

Thank you for your beautiful video. Enjoyed ❤️❤️❤️

Thanks🦑 I favored Ann subscribed.

Great upload.

It’s 3am and I’m watching octopus videos lol

Absolutely beautiful documentary👍👍👍👏🏻👏🏻

Thank you so much for posting this wonderful video, showing the “ majestic beauty “ of the “ enormous “ diversity, of marine life in our World’s oceans . Is absolutely “ amazing “ breath taking. Peace and love brothers and sisters of good faith 👍🤝👏❤️🙏💪❤️🤣🌎.

as a chef, is it bad that i start thinking about how to make a good dish with all these seafood....smh 😁😉👌🏽🤪

Enjoyable and interesting. No squids and octopuses in first 24 minutes except for noting an unnamed new species of squid, fishermen delivering their catch to the market, and a short visit to a museum.

What an inspiring video!very beautiful!ive always have loved octopuses esp.the lil ones!it bothers me to see or hear how we are ruinin our own oceans n the creatures within!smh!🤦‍♀️😥🐠

Check out "My Octopus Teacher" a short film/documentary on Netflix!! Filmmaker Craig Forest spends an entire year interacting with one octopus off the coast of South Africa in like a kelp forest or whatever they're called lol!! It's pretty astounding how not only how intelligent they are, but also emotional too!!! You can actually watch over time how the octopus and him form a sort of bond. I believe it won an academy award for like best documentary too in 2020. I highly recommend checking it out though!! Especially if you're watching a documentary like this!!

Amazing creatures 😮

Great to hear a commentary using scientific name and all else is great

Alternate title - 25 mins of fantastic shark info followed by 26 mins of squids and octopuses 🤷‍♀

🦑🐙Great Video 🐙🦑

I believe that a research team recently got footage of a giant squid underwater.

Excellent production....great narration voice and soundtrack. Great filming...Really impressive and enterrtaining as well as informative. Great documentary overall!!!!!

Just beautiful thanks to everyone God Bless you

I enjoyed this.

thank for the free documentary. Very usefull

Outstanding documentary! Thx

if I saw a octopus in the ocean id probably freak out but at the same time their so cool and interesting to watch
