The Extraordinary Secret of Cephalopod Vision
HTML-код
- Опубликовано: 4 май 2016
- Cephalopod vision has always been a mystery to scientists. In spite of being colourblind, their behaviour shows they are able to distinguish colour, and this is due to the shape of their pupils.
These findings were made by Stubbs & Stubbs, 2015, who discovered that the U or W-shaped pupil, gave cuttlefish, octopus and squid eyes a unique way of diffracting light and detecting colour.
This is a video-adapted version of my winning talk in the FameLab Heats 2016 in Oxford, and content for #CephalopodWeek.

Tier Zoo sent me. And I'm not disappointed.
Same mate
Same, I am disappointed... I thought cuttlefish were wizards!
Same.
I can see this ability being pretty OP in water environments, I would love to reroll a cephalopod but their lifebar is so low you barely have time to learn all abilities.
Same here. Though I did know about this when it came to cephalopod eyes. But I am not saying no to seeing a re-construction of a animal vison!
TierZoo brought me here! That vid with cepha-lo-vision was amazing! To be fair, cephs can pour more points into their eyes, since being underwater protects their eyes from a lot of the worst radiation from the sun.
Tier zoo bought me here too
Me too
Yet another from Tier Zoo!
Incoming swarm from tierzoo. Nice video
It's a crime this doesn't have 100 million views. This is one of the most interesting thing's I've ever come across on the inter webs.
I was completely astonished by this research which shows the clever way in which octopus, cuttlefish and other cephalopods are able to detect colour, despite technically being colourblind! I'd love to hear what you think!
Octopus has the biggest eyes, bigger than a football.!!!
Awesome way to differentiate colors...
But i thought cuttlefish had many types of photoreceptors... maybe im confusing them with another animal
Mantis shrimp... thats the animal I was thinking of.
if a ceph can differentiate between colors than would it not be color blind by definition? How do we know that they do not perceive their world in color much the same way we do with the hardware they came equipped with? wouldn't that simply be a matter of processing
Hey great work on making this video, hope more people watch it. Just goes to show, you never know when a video you make will get more traction. Cheers.

Who else is here from TierZoo?

Guys I need a quick tip. Is it worth it to spend some evolution points to spec into cephalopod eyes?
@@TheWoodenshark Cephalopod eyes are certainly very good, but compared to the eyes many other creatures have, they fall short due to not being able to see many wavelengths of light at once. For this reason, I think it is best to go for cephalopod eyes if you need a lot of evolution points to spec into more advanced traits, such as camouflage, which is what many of these builds have gone for.
K, thx. Will go into camo.
No one:
Cuttlefish: (w).(w)
i found you through Tierzoo's Goat video, this is an awesome video. Good job :P !
Here from Tier Zoo. Learned a lot and now a subscriber :)
Welcome!! 😊
Tier Zoo shall bring you lots of likes these days!
This video is about to blowup!
How do you now that, brother goat?
@@syaondri Thanks, cap!
Woah, this blew my freakin mind!
That is such a crazy and unique evolutionary adaptation, and super effective! Why evolve extra cones when you can just change the shape of the eye to make it focus between different colors instead of between objects in the environment!
Such a cool video! And I love the simulated cuttlefish-vision... that really helped me understand what was going on. Very neat! ^_^
+Kristen T. Thank you so much - really happy to hear that! :)
I just found your channel because of Your vid on Tom Scotts channel and i'm really impressed, keep up the good work!!
Who is here from Tierzoo
Tierzoo rank/makes tier lists for creature categories and species and such - so you can make a better decision in your next playthrough on earth
So when a cuttlefish does those colorful mating displays, they are rapidly shifting in and out of focus from the intended mate's perspective? That must certainly be eye-ca...attention-grabbing 😊
Hadn't thought of that, guess it makes sense.
This has actually been a burning question for me ever since I learned that cuttlefish don't have color receptors - how the hell does a color-blind animal change color to hide itself? Now I know, so thanks.
I've just just discovered your channel, and I'm really glad I did!
Your older videos remind me of Science with Katie. It'd be cool to see you guys collab on something!
Great video! Loved the "ceph-eye view" at the end. :D Thanks for the link to the Stubbs & Stubbs 2015 paper; very interesting.
+flareblitz2010 Thanks for such a lovely comment! It was lots of fun to make the cephalopod vision simulation-reconstruction. :D
Perhaps the best RUclips video topic I have ever stumbled across.
You are super cool for knowing this! Thanks for explaining!
Awesome Video Ines! Can't wait to see more of them XDXD
+Aniq Ahsan Thank you so much Aniq (lovely to see you here!)
The plan is to have a new one every other Thursday! :)
Thanks for sharing! I love videos that teach interesting lessons in a short time, I know these short videos don't provide a lot of ad revenue, but it's awesome for me as a viewer to learn a concise lesson without having to watch a 20-30 minute video, thank you!
I noticed all of your videos tend to keep to this shorter format which is why I've got to leave you a subscribe and a like, educational videos are my go to here on RUclips so its nice to find someone who tends to keep it nice and concise!
Love it! Great explanation!
great video! Very educational. I love cephalopods. Thank you for making this video. :)
❤️Muchas Gracias Inés por este maravilloso vídeo, me ha sido de gran utilidad!! ❤️
Your explanation was amazing! Thank you😄
Interesting critters who are named after the location of their feet. Now we understand their eyes. However as amazing as this is, the current vision master of the universe is the mantis shrimp. We were once amazed by their 10,000 g acceleration of the claw, but now that is eclipsed by the new information on their visual capabilities. Too much info to list here, but the next frontier is to learn how they communicate with each other using these covert signals.
Haha you can tell she’s very chuffed with her writing, ending on the “more then meets the eye” line.
Great vid!
Brilliant, as usual, thank you.
Great video. Subbed. Keep up the good work!
Thank you so much! :)
Me mola y mucho el estilo, tanto de presentar como el montaje. Y si, he descubierto algo nuevo y curioso de la ciencia, cosa que siempre me mola. ¡Felicidades! Espero ver los proximos y mucho ánimo :D
+Ivan Dequito Me alegro mucho - muchísimas gracias!
Very good! fascinating stuff.
This is really amazing--to continue the camera metaphor, their aperture is wide open but they can effectively apply filters by adjusting the focal length
Brilliant! Thanks
So awesome video Thanks a lot 😃Hope for u the best
Most interesting, something I was absolutely unaware of.
This channel is so good. I'm here from Tom Scott's!
That was amazing!!!
Lovely content. Amazing.
I could watch you lecture about seventh century Nordic poetry, or the number three, and be mesmerized.
Don't know why.
Wow that is crazy!!!! Genius technique
Very beautiful video
Amazing video keep the great work
+DooDchii Thank you very much! :)
very informative, educational! thx Curiosity ;)
I love how there's always something new to learn about these incredible creatures. Even after being dead-set on learning all there is to know about them when I was six years old!
Great vid. Thanks so much!!! I've always longed for an explanation of the iris shape of cephalopods. I'm an optical engineer so I'm eating this up! Also thanks for linking to the Biorxiv source in the blogpost. Why wasn't that in the description?
What I want to know next is if you know the Stubbs'. I want to hear the story of their relationship and collaboration. I bet that would be interesting. Are they Brothers? This question has been a very interesting one and I'm hoping the way they came up with an answer is just as interesting as the discovery itself.
Thanks! Subbed.
Cuttlefish are one of my favorite aquatic creatures ever, this is really fascinating to learn just how their eyes do work considering they're one of the main keys to their amazing abilities. Tier zoo sent me here and I'm definitely happy about it. 😁
what amazing intro music! Also amazing video:)
+Robbie Oosterom Thanks so much! Glad to hear you enjoyed the video, it always makes me happy to hear that!
And yes!! When I was looking for music I was completely blown away by Thastor's stuff.
The intro is from one of his latest songs, Johnson (minute 1:22 - 1:30-ish I believe) - the link is here. ruclips.net/video/D7ReP7K-GrI/видео.html
wow, thank you so much!
Wow, fascinating stuff! You, my dear, are subscribed!
no clue what tier zoo is, just a big fan of cephalopods! great video!!
another youtuber
great content, check it out if u want
Wow, i learned alot in this video. Tier Zoo sent! thank you for your explanation.
The reverb though
Great video. This is the first time I've come across this theory even though it's been out for about 6 years now. Previously only explaination I'd heard was based on the fact they have photopigments in their skill - but they hadn't figured out how that translates to colour vision. It would be great to see if someone could program an AI to use this sort of colour discrimination.
Wow that is sooo cool.
Legend was born.
Amazing
Nice video, I love weird and random facts about animals.
+Munchito696 Thank you so much - that's good to hear! :D
Nice vid thanks 😄
Great channel, I came from your video on Tom Scott's channel via your blog post.
Subscribed.
Same.
That's pretty cool, it's almost as if they can filter their surroundings to quickly take in what's happening. Like if they know the color of their prey, they can simply focus on the color and everything they need comes nicely into focus!
My 9 year old son wanted to know about octopus vision. thank you.
That was fascinating....I hope you may also investigate the Preying Mantis...They have some of the most highly developed eyes to be found in the insect world.
Thanks again.
That was pretty interesting
Now that's just unfair! Why couldn't we get that ability?
@@syaondri
Plankton
Woah I came from tierzoo and am definitely not disappointed, this was incredibly interesting
cool stuff!
+Nick Hamilton Thank you! :)
I’m also here from TierZoo, pretty neat stuff.
2:49 Anyway, if you ask me (which you haven't), I think cephalopods are delicious when cooked with salt, butter, and/or garlic.
can they choose when and which colours there focusing in and out off
I*'m from Tier Zoo, and you have such a beautiful voice
We should not be surprised by these findings. Different environments (in this case in a marine environment) can direct evolution of colour vision along a different pathway, in this case of the highly evolved cephalopods.. Another win for scientific research cf. dogmatic rigidity of creationists. Excellence research by father & son.
Tier Zoo sent me. Love Cephalopods. Found out we have the same octopus plushie.
CEPHALOPODS
MORE THAN MEETS THE EYE
Centorea 88 i actually sang that out loud gdi
So, they basically have a spectrometer in their eyes, only instead of rotating the grating they move something inside their eyeballs.
en.wikipedia.org/wiki/Optical_spectrometer#/media/File:Spectrometer_schematic.gif
Well no shit. I'm blown away.
Evolution FTW!
Thats crazy.
The reason why we need to focus and for our binocular vision is because we are creatures that are designed to hunt prey. To accomplish this we need to be able to judge distance and to see the prey sharply so that we can use weapons accurately. We cannot chase prey down and fell them like the big cats and other predatory animals because we do not hane the speed, strength or body mass.
can you do a video about that octopus plush you have
perfection
what was this supposed to be?
Wow, could this also be why dolphins have U-shaped pupils, or is it probably for a different reason?
does this mean they can only see one color at a time? and is it a choice to see color or does it happen automatically while looking around?
In the current meta cuttlefish manipulate wavelengths of light to help them see clearer and in color
Great video! I'd like to see your full blog post but the link doesn't seem to work anymore?
+nick jones Thank you! :) My domain appears to have expired (in spite of them taking payment). I'll be fixing that this evening and it should hopefully be up by tomorrow
The link should work now - thanks again for letting me know. :)
If a ceph can differentiate between colors than would it not be color blind by definition? How do we know that they do not perceive their world in color much the same way we do with the hardware they came equipped with? wouldn't that simply be a matter of processing?
Dang, cephalopods really are aliens, I'm not sure how I could function with eyes like this yet cephalopods can perfectly blend in with their environment despite only being able to see one color at a time.
I loved the lesson, and just absolutely love hearing your talk! It's all wonderful 😍
When I die I hope my second life is being a Cuttlefish, man they are so awesome!
Now i know why cuttlefish has wonky eyes
Very interesting to see one of the different solutions to vision across the spectrum (pun not intended). There is this myth that mantis shrimps see many more colours, because they use more different receptors. One of these days I will maybe make a video on that if you don't beat me to it, that is. ;-)
+Phrenomythic Glad you enjoyed it! I read a paper recently about their eyesight and it does seem that their eyesight may not be as complex as we thought, but rather they are exploiting a different way of processing colour that's easier to process. It's probably something I'll cover one day, but I do have other visions (and non vision) topics planned before (so you should totally cover it, because I don't envision, haha, such a video coming out anytime soon!).
Draw Curiosity Aaargh! All the puns that such a topic leads to... XD
But yes, that paper is exactly what I had in mind, which is why I termed this a "myth". :-D
Anyways, great! I will keep this on my topic list then! :-)
I look forward to *see* what you make of it. :)
Draw Curiosity Ha! Its release is not in *sight* yet! :-D I still have to put up the very first video in my new series dubbed "Alien Analysis". But I'll *see* to it that happens soon!
'
I have finally starting making my video on this topic and it is *looking* good so far! Thanks for the inspiration!
damn that's cool
She seems so strung out
It was the first video I ever made 😅
Tier zoo is really good publicity.
What's the outro song?
Super interesting! :)
A small request for the next video: slightly lower volume on the music. It interfered with your voice.
+Jim Groth Thank you very much! :) This was my very first video, so hopefully you'll find my more recent content has better audio mixing :)
Draw Curiosity Oh. Really good first video! :) I'll be sure to check out more of your videos.
I can dilate my eyes at will. That’s normal right?
The audio has a really high pitch. Idk if it's my phone or the video itself
This was one of my first videos - took me a little bit to figure out how to record and edit sound better :) the audio quality in more recent videos is much better!
I hate the fact that humans never give credit to the octopi amazing color changing abilities. They're also the true masters of disguise. Not that the dam old lizard. I forgot what it's called.
