- Brittle stars are eyeless, brainless animals that spend their time hanging out in dark crevices of coral reefs. But despite all this, it seems that they can still see...using their skin!

Maybe microbes can see with protiens
Hey Sci Show! I really wanted to ask a question about the coming death hornet invasion. Do you think that introducing small Japanese honeybee populations to European honey bees in a lab and making them cohabitate, and then releasing strong groups of these cohabitated bees offspring into the natural population of honeybees hopefully allowing them to cohabitate with those populations. My hope is that through both the heritage of the Japanese honeybee offspring and epigenetic exchange would potentially give these bees the ability to learn the overwhelming vibration tactics of the Japanese honeybees.
Gotta question to Scishow. Why did we develop a urinary tract through the reproductory organs when it urine could have had it leave through the anus, considering its passing potentially dangerous products through the reproductory system instead of one that is already compromised with feces?
“These brainless, shy animals” I felt that
He's acknowledging us.
I'm aware of creatures that can sense without eyes... Xenomorphs are a great example
Hrfjio - Wait a minute
I thought they had eyes, just that their skullpieces were naturally polarized and hid them.
Huh. Weird.
@@Guru_1092 their tongue has eyes
andy dufrense but their tung isn’t constantly out is it?
Did you notice that the xenomorphs never eat anything but they grow incredibly fast anyway? Did you notice that most xenomorph attacks on humans result in its own death? Yeah they really didn't put much thought into it.
At first glance I misread the title as “How BattleStar Galactica can teach robots to see through skin”.
...yeah that’s probably enough internet for the night.
By your command.
[proceeds to execute code to bring down the internet for 8 hours]
It's most likely not 'seeing' as much as it's 'feeling' light. Probably something akin to our sensation of heat.
A sensation no human could possible understand.
@@aaaaaaaaaaaaaaaaaaa790. I am understand
yeah pretty much. it is definitely not seeing shapes as it would need a brain to interpret shapes... our eyes don't 'see' shapes. They see input that our brain puts into shapes.
I dont believe there are any photocells that can sense heat.
@@tubadude-2269 he meant that their sense of sight is so underdeveloped, it might be sensing light the same way we sense heat.
In a creepy Sam Niel voice: "Where we're going, we won't need eyes to see.."
*I a wise Laurence Fishburne voice: "We're leaving."
Worst movie ever. (At least in my opinion. It seems to have a cult following which I can't grasp. But, to each their own). Still, it did have some pretty good lines.
This will be really helpful for hunting down humans when SkyNet activates.
I too am experiencing graceful degradation. Some might say, I age well.
See Without Eyes is a really great album.
1-800-CONTACT? They can't have my sight! I have special eyes.
Look. Look with your special eyes!
MY SIGHT
Well the brittle star in my reef tank is now 10 times more badass in my mind.
I was so hype to hear about some brittle sun somewhere in the galaxy, but no, it’s just Patrick Star lol
Don't act like brittle stars seeing trough their skin is the most important thing here when you are also talking about animals with crystals on their body parts
My first robot used photo transistors as light sensitive eyes. I also used a neural net and its goal was to learn that that bright light was its food source and always try to go where the food was. Usually it starved to death (battery died) before it figured this out.
"These brainless, shy animals spend their time hanging out in dark crevices of choral reefs"
me
What impressed me most was how it was able to form a plan and response to stimulus without a brain, how? Also can’t all animals see light with their skin, unless infrared doesn’t count?
Sounds more like these Brittle Stars "feel" light more than "see" it.
Hank: If you wanna sharpen your STEM skills then just pay for this online class to help!
Me, a STEM major watching this in between Zoom lectures: am I a joke to you
Thank you for all the awesome ocean facts lately!
Well, since single cell slime mold has shown memory capabilities, it seems that a brain is not required to retain memory. The research field of organic robotics is wide open and extremely interesting.
- And I really want to dig deeper into the field of psychology and see what this means for our models of human memory.
Graceful Degradation is my plan for the next 80 years. Fantastic video!!
Thanks Hank and team 😍
2:53 "... it might make the machines better at tolerating and adapting to damage.... localized injuries wouldn't have much impact on their overall ability to function."
The Borg.
You're describing the Borg.
You're trying to invent the Borg.
Happy birthday hank
Hank good at making words come out of his mouth
So that's why I'm running like a devil is chasing me, when i turn off the lights in the living room and dining room..
Love the shirt!
Hank, your shirt just won the internet.
Our eyes evolved from a patch of skin with photoreceptors...so it's to be expected that we will se photosensitive skin...
That was the mollusks , chordates evolved eyes from extensions of the brain.
00:56 - ...so, that mysterious area in the human brain that can inexplicably sense light would be considered [extra-intra-ocular?] photoreception? 🤔
You mean the pinneal gland? It's not inexplicable. It's the leftover of the pinneal eye or parietal eye of ancient reptiles, also called the "third eye". Except that now instead of having its own eye to perceive light, it receives terminations from eye nerve cells.
Thank you for the “eye skin”.
Happy birthday (on May 5) Hank!
We do see with our skin. When you feel heat, your skin is seeing in infrared.
nihil1 it’s amazing how we classify ourselves as having five senses but we have so many more. The one you stated is one I’ve never really thought about but you are so right. Brings up a new question though, do we feel hot air and/or flame the same way, are those three distinct ways of feeling heat? Or two distinct ways? Or all the same?
True, and not only that, sunlight makes us produce vitamin D
That's not really how it works
Thermoreceptors have nothing to do with infrared except when infrared making things heated. They basically sense the temperature difference with some nerves discharge when they get hot or cold.
@@suzyqilplants ong I'm sure that's not how that shot works 💀
Phft. I can sense infrared with my skin. ;)
I want to say your wrong, but you are technically correct.
Do you want to get touchy robots?
Because that's how you get touchy robots
We detect infrared light with our skin as a sensation of heat. That's part of why we know finding shade on a hot day cools us down. It seems like a lot to ask a person or any other animal to draw a picture of their environment based on that information.
Yup. But when it is windy or colder out. That is not as strong. Or goes completely.
Ok this is friggin cool
Extraocular photoreception ... "Hi, I'm Daredevil ..."
yo hank whered you get your button up, im in love with it
Brittle stars can't see California without marlon branda's eyes
I think I just had a stroke reading the title
Seeing without eyes = impressive. Acting upon that without a brain = amazing!
Great. Take every weakness out of the robots.
Make robots more tolerating and adapting to damage...sounds like a great idea.
if only we could all be more like Ophiothrix suensonii,
what a wonderful world it would be....
Thank you for not calling them "starfish."
I'm pretty sure I can sense whether I am in the light or in the shade without my eyes. Of course there is a threshold, it has to be decently bright.
My Brittle star can sense food the minute it drops into the tank even if that is out of “sight.” My bamboo shark was the same..poor eyesight, good senses. They can “smell” food in the water, and my star will go after it and catch it with its arms and those arms can curl up around food or even pass food along its rows of hair-like projections towards the center.
Okay, but this is a really cool idea for a type of space alien
space alien is a great way to say alien
"It could help robots to operate in much more dangerous and harsh environments."
Elon Musk: Let's send Brittlefish to Venus!
When the light
Hits your arms
Wait a minute
That's not right
Brittlestars
Brittle stars are really interesting animals. Why is so much of sea life so interesting to learn about?
(clears throat) Brittle Star Galactica
So does that mean humans can see infared light, which is just heat, with their skin?
No
The beginning of the video was very confusing, because I thought it was a scishow space episode and that the video was going t be about some kind of star in space.
I love your channel and videos😍
I hope that robots look like brittle stars too, I want weird star robots
I'd love to see what you think of gaming Ai!!! Like warcraft wow ai
See, this is what I want from my movie sci-fis. Aliens who see using crystals from their skin. Steven Universe's gems don't count, even if it is just light seeing light on semi-pseudo ocular photoreceptors.
I never realized some people called them sea stars. I'd always heard them referred to as Star Fish.
On that same topic, I finally googled why the Brits insist on adding an extra "i" to their pronunciation of the word "aluminum." They always say "al-yoo-min-ee-um." Turns out, apparently, they actually spell it with the extra "i" across the pond. The more you know
Please do an episode about the different types of pain like sharp or burning. Also, why our bodies register the pain as such.
Eeeeek! These scared me as a child. They gave me the creepy crawlies and I admit that I’m my knee jerk reaction lead to the deaths of at least 3-4 of these things.
I just avoid the rocky areas now when I swim.
Edit: I finally watched the video. Glad that the star wasn’t on the screen the whole time. I’m glad I made it through the whole video.
We can already design robots with the same ability, using photoresistors. They're very cheap and simple to work with. Brittle stars obviously aren't resolving any details, they aren't focusing light, and they probably don't even care about color. They're really just trying to find a place they find safe. But, they also move incredibly slowly. They don't have to accidentally worry about bumping into something and breaking, in the same way a robot would.
Slow? Not really. Compared to their cousins they can move incredibly fast.
There are numerous decentralized control systems. In vehicles (my field of work), there is a separate computer for most systems. Most operate over some form of can network. It's just a way of decentralization, but if one gets wiped out there wont be another to do its job, and if the network goes down nothing happens. I'm sure the industry will build redundancy in future systems...
This means they can regenerate cones/rods equivalent when they regenerate limbs, right? That could be usefully to study for healing ocular damage in humans.
i have no eyes and i must see
I've been watching Sci Show for years. I liked their videos. That is why I decided to create my own sci-fi/futurist Channel. Sci Show, if you are interested, would you like to have a collaboration? 👍🙂
@Awesome Sauce Thank you so much!!
It is nice to see people inspired this kind of videos and make their own. We need more science and less youtube drama channels.
I can sense infrared light with my fingers.. I do it every day on the stove.
In all honesty finding out star fish had eyes was weirder
I, for one, welcome our omniscient robot overlords.
Ops is are great and all but WHAT ARR THE CRYSTALS FOR?
Probably good vibes
I wonder what senses we havent evolved yet
Well, we "see" with our skin to. We produce vitamin D if we are in the UV radiation from the sun, but not in UVA radiotion from a solarioum. We percieve heat via infrared radiation.
Graceful Degradation .. my life at best.
I knew Patrick was smarter than he seemed
All things Marine 😂
isn't that what radio mesh networking does now?
cool!
Maybe microbes can see with protiens
hmmmmm
I early on hypothesized: body's are 'brain' by deign of multiple cells coinciding as organisms do; however even more 'brain' can be concentrated by having nerves and moreover by having nerve clusters and furthermore in having a central nervous system processor in it's own body cavity: but a brain is the organism sans organ proper. If an argument against this posit can be directed at, viruses, for this purpose; that'd be fine: as this hypothesis engages viral bodies in the same vein as non-brain macro organisms.
Simply - they are walking eyes
Correct me if I'm wrong but we, hooman, can "see" sunlight with our skin? 🤨
Haha.. It's funny how in Wuxia Novels, People can breath with their skin.
Amphibians actually can breath with their skin.
The word you're are looking for here is feeling, not seeing.
They feel-see. See-feel.
Well Helen Keller could sense colours with her hand/skin.
But, usually, current robots have a little brain for, practically each articulation, motor or servo.
Now, I have a hunch that circuitry complexity could only increase as there will be a need for little cpus for each bunch or grid of sensitive covering/skin. So, even more wires and fiber.
Why do we need to study starfish to understand vision and sight? Aren't there flowers and other plants that change their orientation based on the movement of the sun?
AMAZING Video, @SciSchow
What if the crystals between the nerves create a sort of EXO brain. And you kind of neural network that doesn't require the nerves to create the brain. This could mean a lot.
How can mirrors be real, if our eyes aren't real?
So if you hit one with a Laser would it blind the patch of skin you targeted with the Laser. Here is a Question you did not answer
I read "battle stars" 🤭
So you want replicators? Because this is how you get replicators. Decentralised means no Central control for processing. Means no Central off switch.
Late HBD Hank!
these brittle stars remind me of Danzo from Naruto
Quick Question Mr. Green: Whats your favorite colour??
Exoskeletal not endo. Carbon compsites
repair bots
LCD screen reversed with micro photovoltaics
xbox and playstation players on remote repair units and remote battle units
multiple auto functioning control nodes with programmed functions decentralized.
Primary, seconday and tertiary backup main circuits
Multiple decentralized nodes
It is funny how robots are becoming more human and humans are becoming more robot (devoid of emotions).
Graceful degradation is just co-opted borg tech
Why does toasted bread taste better
Great, give robots body full of eyes, so that when SkyNet activates even severed limbs of robots will hunt down humans efficiently.
Graceful degradation seems to be akin to autological.
