The Insane Biology of: The Octopus 

"You gained intelligence?" octopus: "yes" "What did it cost?" octopus: "shell"

I gotta go to work in 4hours and I'm over here learning about octopuses at 2 AM

I hope there is an updated version made. Octopuses and squid are now known not to be colorblind but just as their intelligence evolved differently than chordates their color vision is completely different. They only have a single type of photodetector and the fact that lenses are achromatic and have non-circular pupils and their visual system is much more complicated than ours so as to be able to extract color diffraction around the edge of the pupil and the achromatic distortions caused by lenses.

Ever since I was 8 years old, I've wanted to be a marine biologist. I would always wonder about all these amazing creatures that are found in the ocean... My parents wouldn't let me have my own phone, so I would ask them if I could watch a video on their phone about sharks and dolphins and all marine animals I could think of. My cousin is currently in university studying to become a marine biologist, and she lives on the opposite side of the world from where I do, yet every night, we talk about these mysteries of the ocean through messages. Although I am still in school and still have many years of school and high school, I still want to be a marine biologist. These videos of the ocean makes me even more curios! Thank you for sharing this information.

Having done a lot of diving - I can say that the octopus is an absolute marvel to encounter. Some (mostly the younger ones) are ... So curious. At first it's like "WOW! U THREAT?!" once it establishes that you are not, it's like "Eeer ... What are you then? I've never seen one of you around before." and there begins the act of mutual curiosity :3. You slowly reach with a finger, it sends a tentacle ... you both touch, sometimes they get frightened and clamp your entire hand, flashing black before letting go, but not swimming away. They are playful, find a shiny pebble, hand it to the octopus, it'll take it, check if it can be eaten ... discard it ... then a few sec after send a tentacle back to the pebble out of curiosity as to "why did he give me this pebble ... gotta check again for anything special". They really hold a very special place in my heart, it's not everyday that two species get curious about one another and attempt mutual understanding :)

"Lose your shell, and gain enlightenment" -Octopus

This channel inspires a sense of wonder about nature in me that I hadn't felt since I was a kid. Thank you so much

The craziest part isn't that they can change color to match their surroundings (as Chameleons can), It's that they can change the DESIGN of said colors, to match the contour or natural look of whatever object its trying to match 🤩

> ditched the shell > evolved intelligence So this is what it means to leave your comfort zone

I worked with a marine biologist studying cephalopods. He had one big tank for octopuses and one for crabs, their favorite food. One morning he came in and found that one of his octopuses had pushed the lid open on his tank, crossed the floor and climbed into the crab tank. Soon it became a common occurrence. He decided to give the octopus a mild shock when he found it in the crab tank to deter it. Within days he came in and found the octopus had still gone to the crab tank, eaten it's fill, but then climbed back to its own tank to avoid the shock. They are amazing animals.

This is some crazyy shit to watch at 2am, im absolutely mind blown

That was fascinating. As a diver, I've always had a great interest in octopus. This just put it on another level.

just how intelegent are they? octo : _wearing coconut shell while walking like a model_

Millions of years from now octopi will be studying why humans destroyed themselves.

Your content is so high quality! Congrats! I loved the Netflix documentary "Octopus teacher", cried at the end. These animals are amazing, more than we usually think!

They really hold a very special place in my heart, it's not everyday that two species get curious about one another and attempt mutual understanding :)

Can we just appreciate the fact that there isn’t a single ad in this whole video?

The next time someone tells you, you need to get out of your shell; they’re offering you a path to evolution, intelligence and enlightenment.

I feel it is a possibility that the octopus lost its shell AFTER superior intelligence had developed or atleast began, and was able to manipulate itsself/tools.... Therefore, through evolution it lost its shell to become even more adept at the camouflage and escape tactics it had come to be proficient at.. Cool to think about I just found your channel today, subscribing now great videos!

I watched this video couple of times and maan, i have to say, this channel is just such a jewel on youtube, thank you so so much!

Such content is incredibly underappreciated

Exam in 4 hours, have I studied? No. Have I learned about how octopuses are possibly the first intelligent being? Yes. Am I happy with my productivity? Hell mother f’ing yes.

What a great video, perfect visuals, fluid explanation, not too heavy and not forgiving.

Interesting video. I liked learning how they physically change colour so quickly. Fascinating. ❤ I only wished it was longer and more in depth. Perhaps a sequel in the future? 😊 Thanks for uploading!

I feel like the narrator is going to say "Everything Changed When the Fire Nation Attacked" at any second

changing colors and body textures is incredible but what amazes me even more is the speed at which the octopus does it…it’s freakin insane man

Their eyes are pretty amazing. Ive loved octopus forever but just noticed in this video, their sight is pretty much omnidirectional. They don't have a preference in movement direction because they can don't have as much of a defined front instead seeing and moving in whichever direction they choose

This video brilliantly captures their unique and incredible features! Thanks for such an informative and captivating one!

Octopus: holds out tenticle Diver: shakes tentacle Octopus: ...Damn these four legged seals are smart

When you learn something so incredible and interesting that you feel like you need to go tell someone about it, you know you learned something good.

the idea that another animal from this planet evolves to a point where we could talk back and forth with each other would be amazing. just imagine an Octopus walking biside a human on the street

This is a great video. And just an amazing channel in general. I love every part of science as it encompasses and represents our own inate curiosity as humans. And when it comes to biology I am obsessed. The life we are surrounded by is incredible, and that alone is a reason to live.

“... as fast as the fastest blink you can do.” everyone: blinks

"as fast as the fastest blink you can do" *rapid blinking

Thank you very much for this video. It is excellently researched (from the point of view of someone who does not deal with such issues professionally) and very well done, and it made me think a lot about how us humans tend to make often somewhat hasty and, above all, very often biased judgements about other species in our world. Thank you again for broadening my perspective and for collecting all these fascinating facts about cephalopods.

I love how we both appreciate the ocean with not just interest, but a respect that is given to dangerous things, like an orca

- ''So how did you get into Harvard?'' - ''I lost my shell bro''

Octopus: I lost my shell 140 mil years ago Nature: We gave you camouflage, texture-camouflage, shape-shifting abilities, and the ability to squeeze into any rock. Octopus: ok then.

I don't know how I had found this video but that's pretty amazing the explanation about the octopus skin and the color change - thank you so much for sharing this ;

This is stunning and well done ! Thank you!

Hey, I just had a thought about octopuses and intelligence being social: Octopuses may be social--internally. If their arms have semi-independent cognition, then an octopus mind might be more like a council or group mind than a unitary self. As I understand it, neuroscience is revealing that humans are not exactly unitary selves either. But for us the "multiple selves" are subconscious, more or less as portrayed in "Inside Out." But if an octopus' "sense of self" is somewhat plural, being localized to some degree in the arms, being an octopus might "feel" more like being a vessel with a mind-linked crew than being "a person" as we perceive it. Thus, a form of social interaction and consensus-building would be happening for an octopus at all times. That might explain why they are able to interact socially and play with humans even though they don't seem to have social structure among their own kind. Anyway, it's just a thought. :)

Imagine an octopus is talking about "The Insane Biology of: The Human".

Octopus gives me chills on how unique this creature is

There is a long interesting story of an octopus in the Vancouver Aquarium who dined on specimens in other tanks and was very difficult to difficult to catch in the act because he stayed in his tank when watched. Even from behind barriers.

"Their one of the most intelligent creatures" Octopus : they're*

I'm rooting for the octopus. Movies like to make them seem like monsters, but they really are very vulnerable...

Absolutely fascinating video. Thank you so much for this stunning footage.🙂

What a brilliant production. Thank You!

We wonder so often about being alone in the universe that we sometimes don't realize how incredibly diverse life is right here at home.

Man this reminds me of me and my dad watching late night documentaries about anything. Rest In Peace Papa

i have also been interested in pathology but i am still not sure, and this video really helps!

Octopuses: *sophisticatedly evolved to survive this long Humans: whoa, this animal is amazing! Maybe we should eat it

"Imagine having limbs that cannot move independently" -This post was made by octopus gang

Incredible. Thank you for posting

How do we even imagine an octopus "subjective experience", when its intelligence seems almost more like a collective cooperation with the arms rather than a "top-down" dictatorship (as our brains are, apart from the neurons in our hearts)? Imagine being "the head" of an octopus, sometimes dragged along by the autonomy of your arms. Or imagine being "the arm", dedicating your whole existance to the benefit of the other 7 arms and the head. We cant even begin to imagine the subjective experience of such an organism.

if they taught stuff like this at school i’d actually listen

Can we just talk about how the diver playing with the octopus was the most wholesome thing ever

bro honestly you feel me this one of the best vids on earthington

I have this video almost memorized I’ve watched it so much

My favorite creature ever. I was on a crab ship in Russia. I was the green horn so I had to empty out the pots. I was also making hooch quietly because it was forbidden (it was lighting in a cup) so I could swap liquor with the chef for him making me private meals. One day there was an octopus in a crab pot. I tossed it a live well. Came back once everyone was off the deck. Was gonna take it to the chef. it softly wrapped itself around my arm and I felt like I could see the fear in its eyes. I couldn't do it. I took it over to the side of the ship, held it over. It looked down, looked back at me, let go of my arm, and worked its way down the side of the ship until it got to the water. AMAZING CREATURES!

This is SO interesting

Thank you !! Incredible and so interesting

I have always quiet epicure of your videos. Now, I have to break my silence to express to you my greatest admiration and gratefulness for the creation of these contents. Of a few contributing factors your videos have probably been the major reason for me to develop a free time interest in biology/zoology. I’ve watched several Insane Biologies and my jaw kept dropping upon the magnificent details of some creatures. You made me grow a fascination for so many animals in turn! The quality of your videos is a blessing and gets the best out of RU-vid: entertainment and education in one. Your soothing voice, background music, motion pictures, cuts, structure of the videos and contents make you my favourite RU-vidr and an inspiration to learn! I really hope you come across this comment and can understand how much appreciated your is. I wish you all the best!

“But in their arms, which can smell and taste, and even think” “So, what do you think, arm number 6?” “I agree with arm number 2” “Alright, we’ll go with arm number 2’s plan”

"the octopus lost its shell 140m years ago" poor thing, we should help them find it

So interesting story about Octopus. Thank you.

Netflix: My Octopus teacher. Good documentary with great closeups and commentary. Gods attention to detail, His creativeness and sense of humor in His creation of some creatures is absolutely amazing!!

They dropped armor in exchange of speed.

The octopus is the most amazing creature on earth. Just incomprehensible.

They are really impressing creatures. I love watching them. They are so unique with the ability to change in every colour or any structure,and this very fast. It is remarkable what they can do. Cool video 😅😅😅

can you do a video about snakes? perhaps including the snake detection theory and some cool facts like snake movement etc.

Me: about to go to sleep RU-vid: OCTOPUS!

If octopus had been social being, they will be a entirely separated civilizacion by now.

Amazing. I am going to watch the Netflix series now too. I've been always fascinated by these wonderful creatures. The decentralised neural system , mimicry, gaming, and planning actions are just outstanding.

God this makes me wish I could get back to school and pursue marine biology like little me dreamed of.

"no social bonds, not social hierarchy" Octopus GANG.

I love them so much

Extremely interesting. I enjoyed that. Thx. Watching from Ontario Canada 🎉. Going to check out your podcasts.

I think cephalopod intelligence is “hard wired”. An octopus has a very short lifespan, as little as 18 months, and has to learn everything from the moment it hatches completely on its own. Its mother died before it emerged from the egg, so it is born an orphan. This has huge implications, because despite being intelligent it has no “mentor” to learn from. It’s also a mollusk, so in a way it’s a slug with awesome superpowers. They’re fascinating animals.

6:05 'as fast as the fastest blink you can do' *starts blinking as fast as I can to get an idea >;0

Absolutely amazing!

you did such a good job with this video. Octopuses are a close second for my fav animals :) next to sharks

My favorite part is "how could a creature evolve so differently from humans?" The answers simple evolution doesnt have a set path it's just testing until the test survives long enough to be added to the patch update.

Human: “octopuses inhabited the earth before humans” Also human: * calls octopus “alien” * Octopus: “these aliens got way too comfortable in MY house” 🤔

The more I learn about octopuses, the more I fall in love with this amazing creature. So complex and smart creatures. 🙌

Wonderful content and explanation.

That octopus carrying the two coconut halves like walking with groceries was the best thing ever. “ Do-do-do-do-do. Off to do something fun” 😆 They’re so cute 🧡

“as fast as the fastest blink you can do” Me: *blinking intensifies*

Amazing video! I am amazed by these creatures, they’re so cool 👍

The day we would be able to connect our brain to simulated other ones to feel what other creatures feel (black mirror sci-fi thing for now, but i do have real hope), this is THE animal I will pick. Everything in their biology and brain is sooo different from us.

One of the most underrated facts about them is how they have no front or back. They have complete 360° movement.

The curse of the Octopus: they only live a couple years :( imagine what would be if they lived as long as us.

Absolutely amazing animal and another really great video. I'm hooked.

This video contains so much information And love it ❤️👍

One of the most amazing species of Octopus is the Mimic Octopus, it not only uses it's shape changing skin and camouflage to hide but also imitates other sea life both as a way to escape predators (when being chased by a damselfish it'll make itself look like a banded sea snake, which is a damsel fish predator) but also to hunt (imitating a crab to draw in another crab). The list of animals it's been observed to imitate is quite long (Jelly Fish, Lionfish, Sea Snakes, Zebra Sole, Flatfish, Giant Crab, Sea Horses ect) it has also been recorded imitating at least two species we don't know about (the same shape were recorded in separate locations being used by different individuals).

Imagine octopuses evolve to go on land millions of years later and find our ancient buildings and projects. The explore it then start to restore it and make a new life before the sun devours them whole.

I saw this on my friends phone during our break at work and now I’m watching this 12 hours later at 1am bcz I thought this video would be interesting AND IT IS I love these guys 🐙

That's very nice all the things we've learned about this creature, it's a real shame it had to wait millions of years for the rest of us to get here

AS FAST AS THE FASTEST BLINK YOU CAN DO! Literally everyone blinking as fast as possible, damn thats pretty quick.

Why can't regular schools present content like this? I remember sleeping through my entire elementary classes.
