If Your Hands Could Smell, You’d Be an Octopus | Deep Look

- Those hundreds of powerful suckers on octopus arms do more than just stick. They actually smell and taste. This contributes to a massive amount of information for the octopus’s brain to process, so octopuses depend on their eight arms for help. (And no, it's not 'octopi.')

Everyone knows that an octopus has eight arms. And similar to our arms it uses them to grab things and move around. But that’s where the similarities end. Hundreds of suckers on each octopus arm give them abilities people can only dream about.
“The suckers are hands that also smell and taste,” said Rich Ross, senior biologist and octopus aquarist at the California Academy of Sciences.
Suckers are “very similar to our taste buds, from what little we know about them,” said University of North Carolina, Chapel Hill, cephalopod biologist William Kier.
If these tasting, smelling suckers make you think of a human hand with a tongue and a nose stuck to it, that’s a good start. It all stems from the unique challenges an octopus faces as a result of having a flexible, soft body.
“This animal has no protection and is a wonderful meal because it’s all muscle,” said Kier.
So the octopus has adapted over time. It has about 500 million neurons (dogs have around 600 million), the cells that allow it to process and communicate information. And these neurons are distributed to make the most of its eight arms. An octopus’ central brain - located between its eyes - doesn’t control its every move. Instead, two thirds of the animal’s neurons are in its arms.
“It’s more efficient to put the nervous cells in the arm,” said neurobiologist Binyamin Hochner, of Hebrew University, in Jerusalem. “The arm is a brain of its own.”
This enables octopus arms to operate somewhat independently from the animal’s central brain. The central brain tells the arms in what direction and how fast to move, but the instructions on how to reach are embedded in each arm.
Octopuses have also evolved mechanisms that allow their muscles to move without the use of a skeleton. This same muscle arrangement enables elephant trunks and mammals’ tongues to unfurl.
“The arrangement of the muscle in your tongue is similar to the arrangement in the octopus arm,” said Kier.
In an octopus arm, muscles are arranged in different directions. When one octopus muscle contracts, it’s able to stretch out again because other muscles oriented in a different direction offer resistance - just as the bones in vertebrate bodies do. This skeleton of muscle, called a muscular hydrostat, is how an octopus gets its suckers to attach to different surfaces.
--- How many suction cups does an octopus have on each arm?
It depends on the species. Giant Pacific octopuses have up to 240 suckers on each arm.
--- Do octopuses have arms or tentacles?
Octopuses have arms, not tentacles. “The term ‘tentacle’ is used for lots of fleshy protuberances in invertebrates,” said Kier. “It just happens that the eight in octopuses are called arms.”
--- Can octopuses regrow a severed arm?
Yes!

Glad i'm not an octopus....just imaganing all the time i've had to pick up something gross like a diaper, at least i couldn't smell and taste it as well
Eeewwwuuuuu !!!!!!! Well said 😌😰
If you were an octopus, you wouldn't need to pick up a diaper.

*SOMEBODY ONCE TOLD ME THE WORLD IS GONNA ROLL ME*
awesome video!
at my college's lab we always had to lock the octopus tank so she wouldn't escape. she stole my friend's gopro once and took a bunch of selfies too.
WHAT! Pictures plz or it didn't happen.
those pics got 'em on the front page of reddit: www.reddit.com/r/pics/comments/2xst4q/i_tried_to_get_some_photos_of_an_octopus_but_it/
These are HILARIOUS.
BTW, your videos are great! We're subscribers to your channel. Go science!
ah thank you! i appreciate that :) :) science4ever
you're amazing Lauren...but still miss you Amy..😘
Nooo! Amy.... Deeplook will never be the same without you ;_;
Oh and hi Lauren. Welcome.
Lol
And now, Lauren is leaving :|
@@akinoreh yoo fr!! Waaah!!
you guys deserve more subscribers
Thanks! SPREAD THE WORD.
Deep Look Spread the word? Ok! THE WORD THE WORD THE WORD THE WORD THE WORD
Sjejj Oeoeo3 omg 😂😁😁
Ttttttttttttthhhhhhhhhhhheeeeeeeeeeeeeee wwwwwwwwoooooooooorrrrrrrrrrrrrrrrrrrrrrddddddddddddd
ik, this channel is so interesting and cool! 6.6
I love Octopuses. they're so cute and incredibly intelligent, and kinda goofy. Especially the ones that climb into a conch shell and walk across the ocean floor. xD
Jillybean711 Octopii - just so you know. I wasn't trying to be shooting you down, just passing on info. 😊
Ian Macfarlane they are both ok but "octopuses" is more correct in a way, as well as octopodes
Jillybean711, sorry it has been brought to my attention that you are in fact correct. Octopii it seems is entirely correct as the plural of octopus, however it's is now becoming objectionable, and that the answer given by Lapis Angsty Lazuli, (and used by yourself) is now considered preferable, especially in the UK and the USA. Sincerest apologies. Thank you for your interjection Lapis Angsty Lazuli. I'm away to bury my head in my pillow😳
Ian Macfarlane good night hahaha
+Ian Macfarlane It's fine. XD Everybody makes mistakes. I'm sure you'd much prefer a nice calm and collected correction than a rather rude one. x3
I feel so lucky to have found this channel!!
And we are lucky to have you too.
Wish her nothing but the best! Let's get the new girl a warm welcome hopefully she feels it
Welcome Lauren! Amazing content and quality as always. Thanks to the whole team for these awesome videos =D
Cool profile picture!
For your first episode, you did great! I didn't even notice the difference in voice, that's how great you did. Cheers to future episodes!
Great new video. I wish there were more :( miss Amy but this new narrator is great too. Keep up the amazing work guys. I always look forward to your videos.
0:57
Keeper: i have to go now
Octopus: *hugs keeper's hand*
Keeper: oh my gosh-
Omg those popping sound from the sucker is so nice
Excellent job Lauren! Amy has an adoring crowd (rightfully so) and I'm sure you knew people would miss her, but the transition was seamless. Can't wait for the next video!
the sounds in every video are so satisfying
ohh, almost didn't make it through two weeks without an episode. Love the videos!
Great video! And great first episode, Lauren! The octopus is one of my favorite animals. Watching them move in water is like poetry in motion. One could say I'm a....sucker for them!
We TOTALLY look forward to more videos with Lauren!!
I want it on my back somehow. Lol
BlackEagle352 yeah I need it to scratch my back LOL XD
BlackEagle352 just think how it would look ...loooool
1:02 is actually pretty cute. He’s giving his keeper a hug
*THE HENTAI IS COMING BACK TO ME*
Lauren does a great job! Oh, and also: Great quality, as always :)
Thanks! We appreciate the feedback.
This is my new favorite channel.♥️
Amazing videos.
Thanks!
Deep Look, you are awesome :) I love all your videos 😊
Watching you guys from thailand 🇹🇭 you guys are the most easy understanding channel for knowledge and your quality of videos push the limits even more. Keep up the good work
Your vid is always so educational & the graphic quality is never short of exceptional :-) Deserves more more subscribers IMHO,
Here's an idea, velvet worms, I think they have one of the coolest chemical weapon I've ever seen.
Lovely vid. Thanks heaps.
I love how the music plays in the background and it intensifies when the octopus is doing something. 🥰😍
editing is next level, I like :)
Love the sound effects!
I'm addicted to your videos!!
another amazing vid. thank u
I just loveeeee your videos!!!😍😍 i can spend my whole watching the videos on your channel❤👌
Thanks Soo sha!
"The central brain doesn't call the shots"
Spider-Man 2 was right on the mark
Underrated channel af
Great episode, as always! I like Lauren's voice, but would be happy to hear Amy again sometime. Do you guys have any plans on having her narrate again, when Season 2 of The Leap is done?
i was the only one who liked this comment for 6 years and i just randomly found it again wow
one of my favorite animals.
I like how they can fit through any opening larger than their beak. Octopuses are cool.
And yes Octopi is considered incorrect.
Fun Facts about octopus!: Flapjack Octopus is An cutest Type of octopus!
I love Deep Look and started to get used to the voice of Amy (Lauren has beautiful voice too). When Amy uploads something to The Leap is there any feed or sometimes to get some notice? Lauren great job!
Wow. How can a channel this good has modest subscribers?
yeeeeees! the octopus is one of my favourite animals , sooo cool . amazing video as always
These beautiful creatures do not deserve to be eaten alive.
Yay another Deep Look video!
Oh! You've covered my favorite marine animal! New HD footage of octopuses! And by Josh Cassidy. Happy Valentine's Day to me! Thank you, Deep Look! :)
Great video!
Reading the title I thought immediately that my hands can smell too if I cut garlic. My nose can run, hair can stand, skin itch, feet smell
I love the popping sound.. so satisfying :D
Another incredible episode from an amazing channel 😊
Many thanks, Simon. What should we film next?
Deep Look - honestly, I've been blown away with everything you've done so far. I mean... Roly Polys are crustaceans? That's been my favorite weird piece of info I use as an ice breaker in conversation (am I a nerd?)
How about tardigrades?
At the end I couldn't even tell the difference between the two voices lol
Why do I think that the octupos' eyes are like a MAD reaction
your bids never cease to amaze me
*What did the octopus said to the police during his get away???*
*Octopus: so long "suckers"*
I love this video it's very educational;)
Basically this "What is Happening to My Body?" Video for Octopus 🐙
Why is it so satisfying to see these suction cups. Part of me just wants to play with them
"Hey Squidward, what do you think of this sauce?"
Squidward: *dips his tentacle into the sauce and leaves it in the sauce* "Mmm, nice, tasty."
Wonderful video. Theres a book about them from a woman who befriended an octopus. They’re so intelligent, curious and gentle too. It’s called “the Soul of an Octopus”
hi amy i like your voice when you explain so understanding and thanks
Incendiculum,acetabulum, dang those are some harry potter magic there
love that pop up sound :D
Smell is basically taste. And it takes a tongue to taste. So basically what they’re saying is if your skin was covered in taste buds- like a tongue, you’d be an octopus
Popping sounds: so satisfying!!!!
Octopus watching this: OHH i didnt know the human being wasnt capable of these kind of things!
I just about lost it when she peeled off the octopus tentacles
Never knew it creates a popping sound
You are very good at taking these kind of videos. You can take a video about mole crickets or Camponotus inflatus or phytalmia mouldsi insects but this is just an advice. I am a bioengineer and I want to give you some advices about the fantastic insects. I hope that It will be your success on your path. Good luck, and thank you for these videos. :-) :-) :-h
I love octopus, i think they are the most fascinanting animals in the world. I wish work with they someday.
really well made!
Thank you!
I feel like octopus is smarter than me...It's probably the closest thing to aliens that we've ever seen.
tearing off that giant pacific's suckers must have been painful
also, I'm totally going to make "hundred of suckers" into a sound asset
Octopuses are genius: for me one of the most brilliant and incredible creatures of the underwater world. They can change shape, color and they are very smart.
That's why I have it tattooed on my right arm..
I feel like the reason Octopi have big heads is because they need such a big brain just to operate that body. Camouflage, 100s of individual muscles controlling the suckers that can grab, smell and taste on 8 individual arms that are like long muscular noodles, they spray ink, they are crafty and great problem solvers, incredible range of movements they can do.
Writing this as I watch and listen, and literally and learning that this thing basically has multiple brains all working together. Wow.
Where was this filmed at???
Lauren my fav Deep Look narrator 😍
imagine that person hasen't taken a shower for 1 month amd watched this video then smelled its hand thinking that if he will be an octopus
One of the best Channels on TH-cam!
Thank you! Spread the word.
I'll miss Amy, but glad to have you Lauren!
Dont need a vacuum seal wheres my octopus
Your videos are so awesome it makes my brother intelligent thx for showing us animals habits
You are welcome Cecile!
Plungers are so popular even animals took inspiration
If my hands did smell, that probably means I'd have to wash my hands.
i've just found this channel and i can't stop click next vid
If my hands could smell, that would be the least of my issues
Great Channel!
Thanks!
If there's ever a "Best You Tube Video Title", you really should submit this one. I've seen it about twenty times now, and, although I can't figure out why, I still find it funny every time. Or is that just me?
1:20 "i Phil Swift here for Flex Tape"
Can you make a video about the anglerfish I really admire those
Thnx for the best scientific videos
Great idea - we'll look into it.
On water: Looks like a normal squid
On land: Looks like a piece of pancake
Most mind blowing thing about this: The suckers technically don't stick to the surface, they actually make the surface stick to them instead.
both of them are great, amy or lauren,
What if my feet smell and my nose is running?
That's gonna be my pick-up line on Valentines Day
That's awesome. Do they hold on to their keepers as a sign of affection or more as a, get me food?
i've waited for sooooo loonng for a new episode :)
edward nacion me too
We make 20 episodes a year. Each one takes about 6 weeks to make!
52/20 = 2.6 weeks per episode. Something doesnt add up. Love your content tho :D
If my hands smell, I wash them.
Great video, I did not know that about those suckers so thanks for making me more educamated.
