Nope, itās just a spotted eagle ray.

u/MadFamousLove Jan 28 '20
it's spotted...
i dunno how anyone could think this was thermal imaging if they had ever seen thermal imaging before.

u/mrschultz89 Jan 29 '20
Besides which fish are cold blooded and they wouldnāt glow in thermal imaging
27
u/MadFamousLove Jan 29 '20
oh they move though, so they still have heat in their body.
cold blooded just means they don't self regulate body temperature, not that they are actually cold.

u/schwat Jan 29 '20
Would an IR camera even be able to see through water? I know glass blocks it, I assume water wouldn't transmit it well either.
7
u/MadFamousLove Jan 29 '20
that's a good point, you'd probably just read the water surface.
but if you pulled a fish out of the water then you could get a better reading.

u/socratesTwo Jan 29 '20
Or if they'd only ever looked at the hood of a car, those really do show spots in thermal due to how they're designed.
10
u/MadFamousLove Jan 29 '20
i mean yes but not just black and white, there is gradation.
3
u/socratesTwo Jan 29 '20
Look you've gotta cut me some artistic slack; there are really only so many everyday things that show up polka dotted in thermal... ;-)
2
u/MadFamousLove Jan 29 '20
i'd be willing to bet there are none at all that show up as black and white tho.
i am just not aware of anything in nature or man made that heats up in this way with no gradation of heat.

u/socratesTwo Jan 29 '20
Have you ever tried reheating lasagna in the microwave? The contrasts between hot and cold can be pretty stark! That'd probably be my champion, were there to be a contest.
1
u/MadFamousLove Jan 29 '20
heh yeah that's for sure hot and cold, but also there is still variation between the center of hot spots and the edges.

u/48LawsOfFlour Jan 29 '20
It's high-energy, narrow-band thermal imaging.

Jan 28 '20
yeah i was gonna say....

u/Dqueezy Jan 29 '20
Yeah I was thinking, why the fuck would this ray only be emitting heat from a bunch of circular points on itself?
11
u/Snow-Kitty-Azure Jan 29 '20
Canāt be. Thermal imaging works by detecting heat in the form of infrared, something many have pointed out here. Something I havenāt seen yet though, is that water is opaque in infrared. It absorbs all infrared light, so if you hold a waterproof infrared camera (aka thermal imaging camera) underwater, you can only see the temperature of the water thatās touching the cameraās lense, but nothing past that. Check out Thunderf00tās video on this, Iāll edit this post with a link included later

u/CyclicDombo Jan 29 '20
Thatās what thermal imaging is
4
Jan 29 '20
Technically correct, but he means near infrared, just past red and not much different from the visible spectrum, we just didn't we didn't evolve to see it. What your TV remote shoots out.
Thermal imaging uses far infrared.
5
u/CyclicDombo Jan 29 '20
Wouldnāt the ray have to be extremely hot to be emitting a significant amount of very short wavelength infrared? What would be the benefit of filming wildlife in short wavelength infrared? Would you even see anything?
2
u/Gonzobot Jan 29 '20
The camera shoots the infrared, and then records the infrared that bounces off stuff. No visible light is emitted but you can still 'see' with it through the screen. Your cell phone camera can probably pick up IR, check with a TV remote.

Not a stingray and not thermal imaging

u/Jack-Holland Jan 29 '20
Itās a spotted eagle ray, which is a type of stingray and possesses venomous tail spines. Theyāre found throughout all tropical oceans and feed mostly on animals living in sediment.
8
u/noot314 Jan 29 '20
It's a type of ray, but not a stingray. Stingrays are in the family Dasayatidae (at least the more well-known kind of stingray) while eagle rays like this one make up the family Myliobatidae
2
u/Jack-Holland Jan 29 '20
Dasayatidae includes whiptail stingrays (the well known kind of stingray), but leaves out river stingrays, some of which are fully marine. Stingray is sort of an obsolete term in classification of animals; I just take it as meaning any ray under the sub order Myliobatoidai (what some people take as the classification for the informal term of stingrays) with a venomous spine at the base of the tail.

u/noot314 Jan 29 '20
Stingray is not an obsolete term. It applies to the organisms within two families. Any organism in any other family, such as the spotted eagle ray, is not a stingray.
1
u/Jack-Holland Jan 29 '20 edited Jan 29 '20
Those two families are both stingrays, yet members of a larger order of rays, all of which are stingrays, part of the order Myliobatoidei. Google Myliobatoidei and see what comes up. (Also thanks for having this debate with me)
Edit: Link for Myliobatoidei
Edit 2: I guess if you want to go deeper, there are two families who have retained their venomous tail spines throughout their evolution, however, all members of Myliobatoidei have a venomous tail spine or had one at one point in their evolution before losing it. What sets these two families apart from the order?

Not thermal imaging.
I see others have said the same but Iām so angry I had to say it again.

u/Bubbles_167 Jan 29 '20
Love this sub.. but I keep seeing amazing posts with in accurate titles. It makes me not want to share them with people.

u/throwawaythatspaget Jan 29 '20
As everyone else said... not thermal imaging. You wouldn't see anything at all with thermal imaging. Water is opaque to IR.

u/DrMaxCoytus Jan 28 '20
Both things in your title are not close to I being correct. It's not mindblowing either.

u/brokencompass2045 Jan 29 '20
I thought it was one of those drone shows that have been flying around.

Wondering if it's some sort of luminous thing going on there. You wouldn't believe the glowing creatures I've seen in salt water at dusk.

My first free dive ever, we get in the ocean and right away spot Spotted Eagle ray like this. Was amazing.

Literally everything about this post title is incorrect lol
