- Images of devastated coral reefs, a common reminder of climate change, can give the impression of a static landscape. But time-lapse footage of coral bleaching as it happens shows a surprisingly active process. This video, taken by scientists in a laboratory at Queensland University of Technology in Brisbane, Australia, captures a coral ejecting its resident population of algae. The behavior helps corals survive warmer water in the short term, but extended periods of bleaching can be lethal to corals and the ecosystems they support.

I saw miles and miles of bleached reefs in Maldives and it made me realize how wicked we are to ever have let the ocean get this warm..
Not wicked, just irresponsible.
First just ignorant, then ignorant and greedy.
Yet bleached coral reefs are being replanted with fresh coral and the new growth is thriving. Also, why are corals not colonising areas that were previously too cold for them? Or are they, but these new colonies are being ignored in the name of political correctness, which is in reality incorrectness because a small number of people are making $billions.
BTW check out the disposal of wind turbine blades that are unrecyclable, so are buried to last for eternity because they do not corrode, rot or otherwise break down.
Focusing solely on global warming is highly dangerous because some other reason for environmental degradation is being overlooked.
Coral bleaching is just as likely to be caused by plastic nano- and micro- particles that are known to infest mussel colonies for example.
Heartland Institute recently posted stats for ocean temperature rises to be only 1 oC in the last 200 years, most of which is in the last 70 years of industrialisation, I think we can deal with these small increases without pushing the doomsday narratives.
They also pointed out how coral globally has been actually increasing in recent years to levels much higher than previous.
This video clip is click bait misinformation as this is actually the spawning process of coral giving new life.
NG sensor any scientific data contrary to their narrative, this is coral spawning, not bleaching.
it's coughing its life out. So sad
🤓👆
no he just has smoker lungs

I didn't know what it meant when a coral ''bleaches'', so I watched the video unknowingly what this process was. I got the feeling it was sick, like it was coughing and clinging to life, but I was optimistic and hoped it meant something else. Then I looked it up and it made me very sad, the immature people in the comments disgust me.
I have raise coral and can tell you that is reproduction and life. Bleaching is entirely different. You might want to do more research.
What's your point? And btw, ''I have raise coral'' is not correct grammar, you might want to take some english lessons.
@@acidnidirbyh1105YOU need to do some research. This is the Coral spitting out zooxanthellae, AKA bleaching. Not releasing sperm and eggs.
Earth’s reaction to human existence in a nutshell.
It looked like it was clinging to life.
you, at highspeed, also look like you are clinging to life, just FYI.
Luis Martinez it’s not dead
That is sad, the poor thing looked like it was convulsing.
so sad seeing it die
understand a coral's life and it looks as much like it is dieing as YOU did typing this comment. Perfectly alive.
m m IT’S NOT DYING YET
They can still eat food but yeah they rely more on photosynthesis
@@acidnidirbyh1105 this is not what a healthy plate coral looks like
It is sad to see the damage we are provoking to the world
How depressing, you can tell it's suffering
This actually makes me really sad
that's so sad
This is called a Fungia Plate Coral, similar to anemones because of the tentacles. This is really sad that the reefs are dying and everyday trash pollutes our oceans, one day we will all pay for what we are doing to the earth.
I don't understand why people are making shit jokes for an attempt to get likes. Does this video really not make anyone concerned about the future of the planet?
Agreed
Some people are too dense to have it sink in. To some of them it doesn't matter cause they believe we'll be in living in a magical cloud up in the sky someday.
Concerned but also feeling powerless to prevent it.
I’ve heard once that some people laugh so that they won’t cry. It’s probably the same for some here
This is bad we need to find a solution for coral bleaching 😢 this is emotional to watch life fade away
its suffering😭😭😭
This is heartbreaking.
I had no idea how alive these corals are and it looks excruciating for it.
So many stupid and ignorant comments.
This is 1000 times better than political comments
Sparkey W ??
Sparkey W True
So true
If this is time lapse, how long did the recording of this take?
the music it's not so fitting for me...
What's that background music? I love it.
This is honestly the worst comments ever I can't even count how many I've reported.
Calm down snitch it’s just the internet
it looked so painful too....
Where's the background data for this research? How hot did they have to make the water to get it to expell the algae or were they really testing for reactions to chemicals like those in suntan lotions or runoff from farms/factories?
jjgiordano999 they raised aquarium temp from 26 to 32 degrees Celsius.
I keep corals, my aquarium heater malfunction and got upto 90°f they half of my corals bleached to death, i managed to save some by feeding them reefroids but it took them a year to recover. Btw start saltwater tank to see it yourself theyre generally easy with modern technology these days, ah, what am i saying they always have been easy lol.
You guys should have shown the entire dying process until the coral becomes just a lifeless skeleton, then algae takes over it
I think that this coral was growing in a lab and not in an actual ocean, so they caused bleaching in order to show and study how it works, then made conditions for coral better so it reabsorbed the algae and didn't starved
it looks like when people are put in a vacuum or space with not enough oxygen and start gasping for air...
You don't gasp for air in space, you depressurize and explode. Unless you mean when they're in their suits? In which case they know exactly how much air they have in their tank, and return to their ship long before it's empty.
@@erikdiaz6379 bruh people do not explode in space
I feel so itchy.
why did yt recomended me a coughing coral its soo sad
The spitting of brown liquid at the end is releasing the photosynthetic bacteria. They will sometimes do this if under too intense lighting as well
Look even the coral is sighing at humans.
Sad
the fact this video came up on 7 yrs ago and today in 2024 this phenomenon of coral bleaching still happening badly all around the world is so upsetting , people doesn't care at all about ocean but once they don't get any resources or the discontinue of main providers on earth which is plankton and algae , the bring on their edge and fuming talking about how people doesn't love ocean ...
song/music is 'Staying Close' from Ambient Drama 2
Ignorant coments .. the corals are the main source of oxygen on earth , the spur released is pure oxygem , when it reaches surface ita released into the atmosfere ..
I wonder how many times this happened over the course of geological time? During the Permian mass extinction of volcanism, and the extreme levels of CO2. What allowed corals to survive climate change then?
I think that even in the most devastating scenarious of climate change coral won't go extinct entirely. There will be a lot of damage to their population and a lot of its varieties will go extinct, probably they'll need tens if not hundreds of thousands of years to build new reefs and their disappearance for such a long time will have a great impact on many species including humans. But I think that it won't be the greatest challenge that corals faced through their long history.
And about permian, at this time corals were pretty different compared to modern ones. Nowadays many varieties of coral have symbiosis with algae that povides food to coral via potosynthesis. But when conditions for coral aren't right, algae may start producing harmful compounds, so in order to protect themselves corals can temporarily get rid of the algae in this very process of bleaching. It's dangerous for coral because if bleached for too long, coral may starve, but ability to bleach may save coral's life if conditions will be harmful only for a short period of time, since it could reabsorb healthy algae and reverse its bleaching. Symbiosis of coral and algae became a thing only in triassic, before it all corals lacked both algae and the process of bleaching, instead they were eating plankton, algae, worms and even fish in order to get all of the necessary energy (modern corals eat too, but for them it's not the main source of energy)
@@akeem2983 Thank you for taking the time to reply, I'm taking geology in university and I'm enthusiastic to understand and learn about everything.
Coral bleaching is like a relationship with a bad break up. Coral and zooantellea is having some stress thats affecting their relationship and its becouse of us, global warming, ocean acidification, pollution and human activities.
Zooxantelae becomes toxic and corals kicks them out, but they'll starve as 90% of the corals food is produced by the symbionts
SO A SERIOUS QUESTION HERE: What just happened in the vid? i dont know whats bleaching for a coral, more information plox
***** algae is its food?
+nacha laica No, the algae produce food for the coral, and give it color. Higher PH levels cause the coral to expel the algae and eventually kill itself.
@@DemonJolt lower pH not higher. Acid is below 7 and alkaline is above 7
@@DemonJolt higher ph levels or temperature? Or do both correspond with each other?
Theres a bunch of reason for a coral to expel its symbiotic algae, one main reason of this is the temperature rising, 90 degrees and above will kill the algae, in the reef aquarium hobby its usually bad parameters like ph and alk also mag, and well bad lighting as algae uses light for photosynthesis.
WHAT IS JUST HAPPENING
mazen mazen A coral is releasing that plant cells inside of it that give it life because they are no longer working. This is a result of heat stress.
Wow this was really painful to watch.
Wow.....
looks like its throwing up
😢 sorry my little friends.
Life exists in different forms.
Wow
NG sensor any scientific data contrary to their narrative, this is coral spawning, not bleaching.
my question is.. why did you filmed it instead of saving it
Saving it requires time, once they expelled the photosynthetic algae its over for that algae but not the coral itself, theyll have to feed it and nourish it until it regains theid symbiotic algae.
But why does bleaching corals=death, cuz some corals need algae to eat, without it theyll starve but it will take some time for them to starve as they can still technically eat via their mouth.
Research in order to save it.
how long did you record
Poor coral :(
I'm confused. 😟
The coral was dying
At first I thought it was a process it had to go through but looking at the (...more concerned?) comments and watching the recommendes video (about what coral bleaching is)....I finally understood what was happening....it's really sad....
(Couldn't think of any other word atm)
this is so sad to watch, we have failed our planet
One of the strangest things I've seen
Vanguard84 it’s dying-
It sneezes out all the zooxanthellae
may i ask ,what are they releasing?
algae and dead cells
cool thx for the info
Cupid Kid zooxanthellae
ok! that ruined my day! poor guy...
absolutely cooool☺☺☺
thank u thank u thank u for the video!!!
this is messed up.
saddest thing I've seen on UA-cam
It sneeze?
WTF did i just watch
A coral dying.
Nafisa Humyra Yeah that's my name what you read.
It's pollution not tempreture
Prove it then
i have always wanted to see a breathing lump undersea. thank u
the top actually looks like lips and I'm not sure if I'm weirded out by that or just in awe
😂😂😂😂
W
You seem like a breathing lump above sea.. hopefully you cease to exist soon as well.
What
you can tell its suffering from from coral bleaching
I dont want to sound disrespectfull towards mother nature but good god that is discusting
Το κοράλι πεθαίνει :/
When you smoke for the first time
Coral is symbiotic with algae called zooxanthellae that live in tissues and give color to coral. When this algae are released, coral bleaching occurs, and the nutrients to coral reefs are interrupted because algae provide 90% of the energy needed for coral. Factors that induce coral bleaching include oxygen deficiency and salt change due to an increase in animal plankton. as a result of overfishing of fish with an increase in water temperature or a decrease in water temperature.
🙏🙏🙏🙏
Mr Stark, I don't feel so good
I know this is a serious video but this makes me feel sick....ewwwwe
me too
Gross and sad
Love this videos!
its amazing :)
what's that gas or whatever it is that the coral is spewing?
Its algae
not the bleaching........the corals fertilizing😇😇
Right? I think thats what its doing here, its a male fungia coral and releasing sperm, but since it natgeo they probably know more than I do though i do keep corals and ive seen one of my coral bleaching, it actually releases this brown stuff that looks like a poo, it does make sense since zooxanthelae color is actually brown.
It's so sad :(
wot is it happening is it coughing wot
for an explanation of what is being shown, go here

sorry nature
Any one know the name of this piece of music?
Most likely several days, possibly even weeks.
song/music is 'Staying Close' from Ambient Drama 2
First I guess
It’s just a coral people!!
It’s depressing seeing weird comments 😔
If the coral start bleaching at a great rate this means that the water quality has dropped significantly and in turn depletes the ocean food chain by not taking part in the cycle of life.
This is just sad..thank God scientist are making artificial reefs or we would be so screwed ..devastating..half the great barrier reef seen from space is desimated
It's the blob monster from that game Inside that Markiplier played
3 a galar corsola irl
2 so sad!
1 it looks more alive then ever
sick vape cloud dude
Womp womp
For god sakes , will someone administer some nyquil cold and sinus, it's sneezing like crazy! 😯
I don't get why this is cool I'm a saltwater guy and I would love to have one of those corals in my tank. so why the bleach??????
its not adding bleach... its coral dieing
ok what a relief still they should call it that
+Mr N The coral is expelling algae that normally resides in them and give them nutrients and their vibrant color. After this unfortunate process corals turn white due to the absence of algae and that's why this is called "coral bleaching". Coral bleaching is happening all over the world due to increase in ocean temperature i.e. global warming. If the temperature doesn't decrease back soon enough the corals die. So many corals have died already.
+Stephanie it actually makes sense though if you think about it. Why would a large volume of algae release be beneficial as a reaction? It could be the algae is liberated to grow in matt form, that would blank the sun out and thereby cool the waters. Trouble is, that strategy has not worked, the result being the coral dies.
This bideo is gross lol.
belching, not bleaching.
Poor animal :(
Nossssaaaaaa
これを見て エヴァのあれそっくり!と思うヤツ多いと思う。
cool
First
lol
Damn nature you crazy
I was told it becomes bleach white that's not an entire time lapse😠
I wish I could bleach myself
equivalent to saying " I wish I could kill myself."
