Snakes use two or more heat sensitive receptors (not eyes) to detect heat, and they then overlay that infrared information with what they see with their eyes. It's thought it evolved not as a means to catch prey, but instead to seek out thermal biases in order to warm up or cool down, and over time that sense has been incorporated into the seeking of prey.
the thermal imaging of the camera is about 100X better then a snake's. Snakes see shape but not detail. They see somewere around 2 degree variation from what I remember. The camera image shown here was like .005 of a degree.
sailure1 - It appears to mainly be mental and not changing their actual vision but I'm unsure of that.. like there's been studies of blindfolded snakes catching prey and all that just fine without any vision at all.. their normal vision isn't that greattt.. it makes me wonder about snakes like woma pythons and stuff how they hunt in burrows where they theoretically wouldn't be able to see anything and womas for instance don't have heat pits. So they must rely only on their jacobson's organ mainly.. it's thought all snakes have a slight ability to detect heat but yea.. their eyes are more suited for the dark but I donno about pitch black. Like a cat can't see shit in pitch black.
Gilbert Flowerface I own a blind Royal python. He hunts just fine, but misses his prey item a lot and even strikes where the prey was not were it is. I once thought he was striking at a reflection in the glass, but now I think its a residual heat signature. He wont eat dead items even if I warm them up.
sailure1 - (I kind of said this already I think but ohwell) That's interesting.. it's thought that they create a mental image of what they detect with their heat pits, even if it's something behind their heads.. which is interesting, they only see in black and white.. but in their minddd they can see people as like.. red.. but yea this video is a bit extreme. But then they also don't even need their heat pits or vision.. since their tongue is pretty good and how Womas hunt in burrows.. maybe your snake is a bit more gumpy because it wasn't adapted that way as a species so it's not coping as well. That's odd it only eats alive.. maybe it's just not confident enough.. but it should know from it's tongue what the deal is.. as long as you gave it a solid effort.. I think a lot of people who think they can only feed live often don't try hard enough or they give up too easily or don't try enough methods to make it work.. not all of them but yea.
I like how the snake regulates it’s temperature around it’s receptors to minimize contamination from it’s own infrared radiation. It’s the coldest part of the snake I can see on the thermal image.
Snakes are dichromatic, meaning they can see two primary colours, blue and green. In addition to their colour vision, many snakes have developed a sensitivity to UV light, allowing them to see in low light conditions. This adaptation was found in the majority of snakes analysed in a study.
So if you use a snake with no heat pits.. it should be fairly oblivious to it... This snake located it but I assume it's jackobson's organ told it that it's not something to eat. It can also use it's tongue and jackobson's organ to detect it to a degree.. I assume that's mainly how woma pythons (without heat pits) can hunt in burrows.. their eyes are better for darkness but I donno about pitch black.. So this is literally how they see with heat it seems (well to a much lesser degree since this camera is way better than snake heat pits)... and when they don't see heat it's just black and white since they can't see colour. Also what they see is pretty blurry and shit with heat so their brains act as correction to make the images better.. This sight also works when they are blind folded.. showing that they don't use their eyes in the literal sense.. it's all in their mind.. seemingly.. or maybe just mostly.. I'd love for someone to reply to this comment with some knowledge on the area.
You are correct, snakes are known to have poor vision because they have so many other senses to work with that we dont. With heat pits (in snakes that have them), jacobson organ, and their ability to feel the slightest vibrations, vision is secondary. The only thing I'm not sure about is you said this infared camera is better than heat pits. If you meant its better at reconstructing the image using the heat patterns thats correct but in terms of detecting heat, snake's heat pits are a lot better than even our best IR technology.
those were the nostrils. they are black because the snakes exhale is the same temperature as the surrounding air. snakes intake and exhale of air is not heated by the body.
What if there were glass between the snake and the ballons, would the snake still see the heat? - I think not. This would be a very important - revealing - experiment as the IR camera does not see the heat if behind glass.
Why make the balloon swing? Won't that make small gust of wind that it could feel? Also balloons have a smell. It's still impressive that just by some warm water it becomes so bright by infrared light!
MujakiKid the way the camera displays the image ...... bright white balloon and orange snake....is relative to the overall temperature range that the lense is picking up....so it would look the same if the balloon was at 50 degrees and the snake at 40 degrees and the background temperatures at around 30 degrees...... hope I'm making sense
I'm wondering, does this leak into their vision? Do they see some type of glowing like the camera? Or is it some completely different sense we can't comprehend?
+Winnie Blues mate They don't "see" it in a sense that we or the camera see things. They sense it. They feel it's there; like when you keep your hand on top of the oven.
Looked this up to see if snakes could be seen in the thermal spectrum as a lot of controversy about the latest Predator movie Prey where a rattlesnake kills and eats a mouse then shortly after it notices the Predator and tries to poison it but the Predator spears the snake's head. Didn't expect to hear Patrick Stewart aka Jean Luc Picard doing the documentary on this
Cold blooded doesn't mean that the blood is literally cold. Cold blooded means that they cannot maintain a constant body temperature like warm blooded creatures, so they have to seek out heat and cold on their own. Like in the video, the snake showed up on the infrared camera, even though it is "cold blooded".
while infrared may have advantages for hunting, i would absolutely hate only seeing infrared. i always thought that snakes had regular eyes (not perfect though) and used smell(tongue flicking)

this experiment is about howto detect snake right?.... really need your comment please,,,i am doing a project which is about how to detect snakes in the jungle,,,
If they produced their own heat they would over heat. I've been working on a 400 degree grill 5 days a week for 10 years and now I need a heat source to stay warm because my body adapted to my surroundings. But I no longer sweat on a 400 degree grill at all, I tested myself and I only sweat when my grill is at 450+ and the hottest of summers produce no sweat on me and im comfortable when everyone else is "dying" of heat. The only drawback is on the cold days of winter I need 300 dollars worth of winter gear because that cold air pierces me to the bone and I shake and shiver quicker then my peers. Interesting stuff really.
your blood is not cool/warm. neither is their blood. That's not how infrared radiation works. You ever heard the term "heat signature"? what the camera sees is basically an area of heat/warmth. As humans can both generate and retain a certain amount of heat but we would leave "ghost trails" of heat wherever we went (if we're walking barefoot) which is why reptiles can track us so easily. for snakes, they can't generate heat but they can retain/store+regulate heat energy to keep warm. That's why you see snakes sunbathing sometimes. It is to store enough heat so they don't freeze to death at night. So what you see in the video is the snake's retained heat from being inside the bag possibly under a UV light previously before the camera crew started filming. A snake without a heat source for too long... Or recently swimming snake... Is practically invisible on an infrared camera. Please look up how infrared radiation works first before asking daft questions.
ok.....his example was not so correct, snakes they can sense heat in dark or in light....but there not so idiots to strikes on plastics, or wooden or metal materials !!!
I didn't think snakes emitted heat at all, so it's interesting that the IR camera could even detect his image. they have a highly evolved sense of smell, so I doubt he struck at the balloon, unless he was very hungry. In that case, if he struck and coiled it, that would be very dangerous for him. I'm sure they somehow prevented that. I also doubt that was a wild snake. He looked much too chill in this situation, around humans, to be a wild caught snake.
+Mikka Mills At 2:30 it seems like there are three balloons at different temperature swinging. I imagine they did not allot time to explaining the experiment and controls in detail.
The cameras see it, but we dont. So the softwares translate the heat seen by the camera into color codes. So its not the heat we see, but a translation of the heat through colors.
Snakes use two or more heat sensitive receptors (not eyes) to detect heat, and they then overlay that infrared information with what they see with their eyes. It's thought it evolved not as a means to catch prey, but instead to seek out thermal biases in order to warm up or cool down, and over time that sense has been incorporated into the seeking of prey.
how pissed was the snake when he bit the balloon and spilled water all over the place?
Maybe it was thirsty so it was very pleased 🥤
Btw this coloured thermal vision from the camera is amazing. It reminds me of the first person perspective of that alien "Predator"
Yeah I watched it too,i remember it
nice
In part 2 with Danny Glover, that generation could switch between different modes in its helmet also.
Woody Harrelson sure knows a lot about snakes

Bad
Snakes need to also smell and taste the air to find their prey.
And it's like the researcher completely forgot that nocturnal snakes have night vision like cats
Yes exactly that is what makes them good predators and Pain nightmare thermal vision is like night vision
@@pain002 night vision requires a little bit of light, total dark balloon in a dark box, even cats wouldn't be able to see it.
So that's how the indominus rex sees

its just so

I just remembered something.
It is no surprise that a snake can detect something in pitch black their senses are far more advance than humans

They can see it shamit
Bro 😂😂😂 came through with the common sense
But can you pinpoint it and hit it accurately? No.
Snake in two boxes
It’s his heat pits on his face that allows him to determine where it is
Good experiment dear,-'such experiments are encouraged for pure science purposes only,-'-'
First he tells us we're looking through the snakes eyes then tells us the snake can't actually see? Elaborate dammit!
If snakes can see hot things without touching, they would go blind if they saw that one metal slide
the display emits light, just saying
true but if he’s only going for the warmest one.
Why was the tip of the snake's head an abrupt black?
those were the nostrils. they are black because the snakes exhale is the same temperature as the surrounding air. snakes intake and exhale of air is not heated by the body.
Thanks.
Aren’t you looking through a snakes heat pits? Like.... they have eyes....

Yes, it would. I own 8 snakes currently, owned another couple of dozens in the past. They definitely 'see' the heat through the glass of their tank.
Glass spread the IR around but it definitelly doesn't stop it.
Why the nose of the snake seems so cold

So Scientific
That was awfully close to his face...
Is it seeing it ? Or is it sensing it through the jacobsons organ? This doesnt proove how snakes actually see.. just that they react on heat..
Can I use that to my Snake friends ?
Cool
Why is Patrick Stewart telling me about snakes
How does anyone really know how a snake sees ? Isn't it impossible to really know ?
The same way they know how other animals see…. Through Science/research study.
Maybe it’s just very sensitive to heat Bc it’s cold blooded
It's the labial heat pits that it has.
Was it just too much to ask to have the snake "attack" the balloon? I was waiting for two minutes for that snake to go full snake on that balloon.
But arent snakes cold blooded? Lol
Yeah u can't really know that that's how the snake sees.. it merely detects heat
would boas be the same?
If snakes see infrared would that mean that a cold blooded animal would be basically invisible to the snake? That doesn't sound logical though...

Killing them is best way than buy expensive antivenom from hospitals.
All living things have different angles of view, such as bats, eagles, snakes and humans ... Is what we see true?
Technically no
while infrared may have advantages for hunting, i would absolutely hate only seeing infrared.
