How we're growing baby corals to rebuild reefs | Kristen Marhaver

- Опубликовано: 22 дек 2015
- Kristen Marhaver studies coral, tiny creatures the size of a poppyseed that, over hundreds of slow years, create beautiful, life-sustaining ocean structures hundreds of miles long. As she admits, it's easy to get sad about the state of coral reefs; they're in the news lately because of how quickly they're bleaching, dying and turning to slime. But the good news is that we're learning more and more about these amazing marine invertebrates - including how to help them (and help them help us). This biologist and TED Senior Fellow offers a glimpse into the wonderful and mysterious lives of these hard-working and fragile creatures.

this is what TED is supposed to be about. well done.
I grew up at the shores of the Caribbean, and throughout I've seen reefs turn from majestic swarms of life and color into bleached graveyards covered in filth. I thank this woman, because she brings me hope, that I will show my grandchildren, at least some of the wonders I saw as a kid.
my knowledge of corals was very limited, thanks for this video!
Adam Chester
no, because i was ignorant on this subject.
Ronald Mcarther is a troll lmao wow get a life
This video nearly got me teary eyed. I hope everyone that watches this, gets inspired to do something that will help our planet and or help the people on our planet. Either indirectly or directly, it doesn't matter but the ultimate goal should be to commit yourself to a profession that "gives", "inspires", "smartens" and makes for a more happier & brighter future.
Watching this gives me hope for the future.
This presentation was so awesome! The way it was explained has brought a better awareness of reefs. I have an innerstanding of what corals are now, and what has happened to them as well as the urgent need to protect and save them. Kristen you rock!
She loves so much his job and she do it with her heart , we can understand from her innocent smile . thank you
This made me cry...
One day I hope to do work I care about as much as she cares about corals. This is incredible and inspiring.
Kristen is a *Hero* !!
This was such an amazing vid. Her way of treating this problem is new and a little sad. Instead of us all coming together we must recreate and make anew. Love the vid never the less.
GO coral baby!!!!!!
Thank you!
Funny how biological and chemical TED talks always seem to have a small audience in comparison to so many other TED talks. Too bad such intellectual interest is so under-appreciated.
brilliant work. thank you Kristen..
An excellent insight into the problems, nicely done and good luck for us all.
She is so passionate about this. She is very inspiring ❤
I now see coral reefs in a different light. Thank you so much.
so beautiful! keep up the research!
Thank you!!
been crying every time I watch this video.
brilliant !! thank you
Coral are the world's greatest natural architects. They are amazing little creatures that deserve our time and resources. They really are adorable babies :3
This is amazing! I've never thought of corals as animals before...
this was awesome!
Such a passionate talk! It's so inspiring listening to people who are sincerely devoted to their mission.
This insightful perspective on the implicit worthfulness of coral reefs offers an amazing paradigmatic shift over the traditional approach to environmental protection: ecosystems are not just beautiful, romantic, yet useless monuments to the natural history; instead, they are mighty active powerhouses which silently, relentlessly and unwillingly contribute to human prosperity, thus deserving respect even from those greedy cynical guys who are exclusively focused on profitability and exploitation. Brilliant speech.
Wow thank you.
very informative talk, great :)
Thank you thank you THANK YOU!!!!!!
that was very nice, dankjewel!
This has the right content for a cartoon film with a message "Saving Coralino" 😁
she's awesome
ah, I really love corals, I wish I could help
great science..
I love coral.
I had trouble with it at first, but it got easier for me.
Hi everyone, someone could help me to find articles about this work ? Thanks ! Lovely work !
"We started watching them at night to see them reproducing..." not creepy at all when applied to any other situation...
wow amazing
I hope this projects are funded in my country too. It's time we need to educate people about this.
I never know about Corals and they are what ate used to see back then when I was in Nigeria. Pls if any can explain more to me I will like to know more about this
I really never know it before in all my life.
This is a noble venture and I'm so glad we're doing it, as a lover of corals and oceanic life forms and an inhabitant of earth, but only a year after this video 30% of the Great Barrier Reef died off in a single season by bleaching as a result of increasingly warming water temps. In other words, it doesn't matter what we do on land to seed the reefs if the water is too hot for them to live in to begin with. Corals are extremely sensitive creatures. They require precise Ph, salinity, temperatures, and trace elements. Ask any saltwater reef aquarium hobbyist; you can kill these things super easily in only a few hours.
What is most likely the best option is to keep corals in aquariums on land until we get our global warming issues under control, then reseed them.
for anime lovers who'd want something with corals, I'd suggest "Eureka Seven"
I now understand my teacher who say stop asking questions to who ever is reading your text
im looking forward to start a coral farm..im really into it..but there seems to be very few knowledge bout them in the internet..its like knowledge about coral raising is limited to us..is it illegal to raise our own coral farm?
hello Kristen
Can someone provide some information about coral reproduction rate? It's urgent please reply if you have as soon as possible
She is doing god's work.
truuuue
For anyone that says they wish they could help corals I just wanna say that u can there is no limit "You are the limit"
👏🏽❤️😍
We should do the same with fish. Not just take it up like hunter gatherers and overfish but plant fish ocean wide. Fish don't take any land, fertilizers or pesticides and look after themselves. The earth is 70% oceans. it provides the best omega-3 fat, vitamins and proteins. We find them by sonar. If left alone other fish and sharks eventually will eat them. We can ensure that there is a plentiful of fish in the enormous oceans.
+rawstarmusic look up aquaponics
Phillip Lam Oh I love it. Aquaponics, ways to use the biggest life habitat on earth, the oceans for plants and fish, foods and veggies. Without sharks you can even take a bath cause we don't need much sharks around. Multiple ways to fill the oceans with life. As long as we plant there's fresh food the year around. Fortunately it's healthy food. If you eat a lot you become more healthy, if you eat a lot of burgers and fries you get less heathy.
+rawstarmusic we need sharks too
Hawaiian Mermaid 23 No we don't need sharks. They make sure that there is not to much of smaller fish like tuna but we need all the tune we can get. The soup we make of them isn't tasty so fish them out and let the oceans overflow with food fish.
rawstarmusic sharks are mostly needed, they don't compete for fishing resources with us, rather they eat ill and old fish, helping fish populations to be healthier, without the risk of epidemics. Thus, sharks help us to have a tastier healthier fish dish on our table
Does anyone know any good conservation projects to which you can donate money to?
Now can I say ...save the coral reefs?
me like coral! me watch ted! me like earth!
I went to the CARMABI website but I couldn't find anything about their funding. I wonder who funds her research. There is no profit in this unless there is a promise for medical applications like she mentioned in the beginning.
"BABIESBABIESBABIESBABIES"
Hope all safe the SEA...
BUEN VIDEO CON SUBTITULOS EN ESPAÑOL FELICIDADES.
Relax
☺☺☺
Ha ha so nervous. Dr. Vaughn send me here...err not really .
Corals depend on many other organisms to survive. A coral reef is the most complex ecosystem on earth. Hard to duplicate or "save"
Is this on a ship?
Moreover Powerfull Baby
4:15 lol corals are comedians
I'm not sure corals have a good shot in the wild. Rising temperatures and ocean acidification aren't doing them any favours. But if we can freeze the eggs for the future - not everything is lost :)
Who’s here 2019🥴
Great work and hopefully you can make a huge difference. I have to say I'm not at all surprised that she's taking Coral sperm back to her lab. This chick digs corals.
Keep calm and spawn coral.
why can't we farm Coral in a salty lake?
What's up
Cute little baby pillar corals.
thats whats up
save the coral reefs sksksksksksksksksksksksskkssk
You say we live on a human planet. We are guess here just like all living things on this planet. The planet can do very well without us. It is up to us if we thrive or die.
Amazing explanation about Corals! I wasn´t even aware that we already lost 50% of them globally.
Here is a link about the current situation and some tips on how we can help Corals:

She looks like the combo of Nicole Kidman and Sigourney Weaver
Funny she didn't even mention the name we (not scientists) give to coral's larvae: jellyfish. Yes, jellyfish and coral are the same thing.
they are not the same thing, they are related but as much as you or I are related to a cat
Mud Hut wrong. Coral polypes actually spew out jellyfish as a means of reproduction and expansion, the jellyfish will then spew out a fertilized egg which will attach to the ocean floor and develop to become a new polype (coral).
I'm a wildlife biologist, you're getting terms confused of colloquialisms. Jellyfish and Corals are in the same Phylum but belong to different orders, the same way mammals are in the same phylum as other chordates. They share similar anatomies and strategies, but corals are not the same thing as jellyfish. They have different genetic lineages with a common ancestor. Research Phylum Cnidaria if you don't believe me.
Mud Hut I'm only a student in biology but I'm sorry I have to disagree. Since I'm french, we might be using different terms and I might be mixing it up. Even so, I have my notes and cycles right in front of me, and it says there are indeed different orders, some only sessile (talked about in this video), some only free (jellyfish), but most have 2 stages: one where the individual is fixed and as a colony makes up a big part of the coral, and spew out a free jellyfish. I'm quoting wikipedia (just so I don't make any error in translating, I cross-checked with what I learned in class):
"In the Cnidaria, sexual reproduction often involves a complex life cycle with both polyp and medusa stages. For example, in Scyphozoa (jellyfish) and Cubozoa (box jellies) a larva swims until it finds a good site, and then becomes a polyp. This grows normally but then absorbs its tentacles and splits horizontally into a series of disks that become juvenile medusae, a process called strobilation. The juveniles swim off and slowly grow to maturity, while the polyp re-grows and may continue strobilating periodically."
the free medusae will then host the zygote's encounter, and the egg formed will develop into a larvae which will attach to the ocean floor to make a new polype.
So, true the jellyfish isn't actually a larvae (I was over-simplifying it, my bad), but what you said isn't wright either.
You basically said nothing at all
El Niño/global warming has destroyed over half the Great Barrier Reef this past month. As well as many more reefs worldwide
everybody is so casual wearing shorts/chappals etc.
very unlike TED.
+Vaibhav Gupta Because they're all biologists XD
iluan Hernandez yeah may be.
When the content of the talk is interesting and important...who cares about what they are wearing? ;)
alejapt i don't care (lol look at my profile pic)
but thought it was interesting if look at ted events it costs $6000. so people are well dressed.
Pointless.
Not to be offensive but all I could here is lips smacking.
Thank you!
