Why the octopus brain is so extraordinary - Cláudio L. Guerra 

this is actually the cutest animation ever

they left out that octopuses can teach other octopuses. there was a study to see how well octopuses could remember mazes. the old food is at 1 point maze with repeated attempts and timed. first time the octopus carefully explored the whole place ate the food when it got there and continued exploring until it was removed. second time it checked out the maze a little and went straight to where the food was. the next time they used a different octopus that was kept in the same tank, it went straight to where the food was. so octopus 1 told octopus 2 what was going on and where the food would be in a maze that octopus 2 had never been to.

y'all remember when Squidward had that talent show and started dancing...

2:57 ARE YOU FEELING IT NOW MR KRABS?!?!

An octopus is generally considered to have approximately the same level of intelligence as a cat. My personal view is that both cats and octopuses are far more intelligent than are certain humans (such as members of congress).

Adorable cartoon...don't be fooled...they are highly intelligent and deadly

"Every tentacle got its own intelligence" Is that why it is so hard to make Octodad fulfill his tasks?

The pink octopus was so cute!!

Our bodies work like a monarchy and the octopus works like a democracy?

the octopus's dance, though x'D

I'm pretty sure the plural of octopus is 83.14159

I know how octopus works Brain:"I want to eat that crab" Tentacles:"ok"

octopus are my favorite animals. they are beautiful, elegant, intelligent. such a great creature

I should breed octopuses for their intelligence, and create an army of loyal subjects to build my undersea empire.

Literally my favorite sea creature. I had a very candid experience when I was 16 going snorkeling with a "baby" octo (it was about 24" in length) that lasted for about 15 minutes. I suggest to read this booked called The Soul of an Octopus. Incredibly nice story. It has some amazing facts about these beautiful creatures

How do you make an octopus laugh? :D With ten tickles ;-) I'm here all week, folks :P

The sad thing is octopuses live very short lives (a few years at most). Imagine what they could learn if they lived a decade or 2.

what was that apple doing in the ocean?

1:53 lol

in 1000 years, we get to see squid man as a new race as they emerged from the ocean.

All hail Cthulhu!

1:44 cute af

3:59 im sorry but- this is just too adorable TvT

The expression of the red octopus at 3:03 is priceless. Well done animators!

Need 7 more 2 join my Octoposse.

cute animation, theese animals are so cool!

Now I know why squid ward is so smart

1:54 so cute. They will rule us and the entire Galaxy one day....

I'm now convinced that octopi are pretty damn cool.

Octopus : Look! A hooman! Little octo : What a strange looking octopus..

i love the little detail in the end when the two octopus hold tentacles

*SO MY YOGA GURU IS ACTUALLY AN OCTOPUS IN DISGUISE XD*

An alien intelligence if I've ever seen one.

At 3:53 the scuba diver's head and hair looks kinda like an octopus

Fascinating creatures. I love the adorable animations you have of the animals. I really love that little octopus. I remember when they discovered it fairly recently a few years back. They appropriately named it Octopusus Adorableis, or something to that effect. It's the perfect name for the cute little creature. They would make awesome pets! :)

When you realize that 3:25 is from Finding Dory

I just cannot get over how cute and high quality these animations are.

Those octopuses/octopi/whatever are so cute!

In spite of what Claudio L. Guerra (who wrote this lesson) teached us, the human somatic nervous system (SNS or voluntary nervous system, the system of voluntary movements through the skeletal muscles) behaves exactly like the octopods' brain. SNS also has a behavioral library from which it selects behavioral responses: when we have an intention, as the signal travels through the network, the SNS pickup the message and jump into the action to command the movement selected from the library which is selected in its wholeness, not moving the individual parts. To be clear, when we decide to grab an apple, the SNS selects the entire packet of answers for grabbing the apple based on the information collected at that moment from various channels, for example the distance between the body and the apple. These are clearly discoveries only from the early 2000s thanks to functional neuroimaging techniques, but as early as 1900s scientists such as Moshé Feldekrais speculated this and created movement educational methods based on this principle of our nervous system and that's why in motor rehab experts don't work only on the individual bodyparts but on the whole functions (to grab the apple in our case)! :) Anyway this is an exellent lesson, thanks you TED-Ed!

1:46 That octopus be vibin' man

I love octopuses. I had to study them for a lesson in college and they are amazing, really smart. We have a lot to learn about their way of life.

This animation honestly makes learning enjoyable for me. Thank you. 💜

4:00 made me cry

The pink octopus is so damn cute.

This is the best animation of Ted Ed, it´s very fluid and flexible and complex.

The eyes of octopuses (actually cephalopods in general) are amazing as well! They are actually better than ours because they don't have a blind spot like we do.

*Allowing their limbs to any point and at any direction* Dang they're the best dancers!

3:56 awww so cute.

There ought to be an episode on Ctenophora, and the evolution of neurones independently of other animals, as well as the determining evolutionary differences between ctenophores and other gelatinous animals. Beroida is especially interesting, being one of the smarter ones, and I think they deserve at least a small mention in the video. Thanks!

I thought the plural is octopussies.

The quality of the animation in this video is ace!

So interesting! I always enjoy these TED-Ed videos. Thank you!

these are one of my most favorite animal.. theyre awesome

1:48 PLEASE make this a gif

the animation in this was incredible!!!! just so cute yet appropriate. it fitted perfectly

As always the animation is adorable!!

THIS IS TOO CUTE how do you make it? :3 Too adorable :3

excellent video, complicated scientific stuff made understandable for everyone and well made animation too :)

I love the ending! so adorable!

This was so useful. Thank you for letting us know!

The best thing is that we can learn so much about our intelligence by exploring octopuses! We need to have an octopus department in every AI lab lol.

i'd say the plural of octopus is "octopi" since its kinda more appropriate kinda like cactus with "cacti"

octopuses (or octopi, whatever) are my favourite animals, and this adorable animation just made me smile ☺

Octopi 🐙 would make the world’s greatest drummers

Splatoon 2 Octo Expansion bought me here xD

"AWWW you made me ink!"

that ending was adorable 😄

Amazing animation as usual! Loved the dancing octopus!

Octopuses are awesome 🐙

1:46 what a cutie!!! :D

kuddos to cinematic.se the team in charge of these animations. this one, and the tardigrade, are definitely so funny. You deserve an Oscar !

yay, finally a cartoon animated octopus THAT ACTUALLY HAS EIGHT ARMS

"shake its tenticles" insert lenny face here

I'm getting Splatoon lore vibes

CORRECTION** Order : Octopoda Class : Cephalopoda

That last scene was so cute I melted

Here's to hoping we find something similar on Europa!

oh so thats how tentacle hentai works

I always knew the Octopus was special! I've been interested in them since I was very young, one of my first class talks at school was on the Octopus. Still learning about them and collecting Octopus-themed things today! Aha ha

Now imagine frying and eating them while they still alive :(

Cutest TedEd cartoon yet; lol, "captain's cookies" :D

Octopuses are the best.

they look sooo adorable

I like the open mind to accept the possible that is some create may intelligent than people. Especially, showing they are connected by love in the end of this video.

I FOUND DORY!!! 3:25

"They don't have lungs, spines, or even a plural noun we can all agree on" Well I know quite a few humans that don't have spines.

1:42 IM DYING OF LAUGHTER

That boy at 1:42 started popping and getting it in. I died. 😂💀

So an octopus is essentially a tentacle hivemind?

3:56 " daddy what's that?" "Its called a human." "Will they hurt Us?" "Probably not." "Hold my hand just in case."

Love Addison's narration😍

Of course he's only a little octopus 🐙 but I was really surprised by his strength!

of the plural form of octopus isoctopi and the plural form of cactus is cacti why don't we call the plural form of bus "bi" ?

_"who knows what other forms of intelligent life are possible, or how they process the world around them"_ the video says & I think that is one of the most interesting questions from this! Loving just the octopus intelligence & how, but apply this to plants & you open up a Pandora's box! (plants have been demonstrated to be capable of memory & other traits associated with intelligence, a similar system to the octopus could explain how)

I love octopuses! They're cute!

This sheds a new light on Dr. Otto Octavius' misbehavior

They're such smart and majestic creatures yet these mukbangers are still eating them alive acting like there's nothing wrong with that

hi I'm a pinniped. I'm eating an octopus while watching this interesting TED-ED video.

1:44 Its so cute oh my god. Its so CUTE! I mean look at him, hes like "Im an octupus and i have wiggly arms. Wiggeli-wiggeli" I bet his motto is "Dance like nobodys watchin" ^^

This video is truly the Dadliest Catch.
