- Dig into why jellyfish populations have increased, and how leatherback sea turtles can help get their numbers under control.
--
Over the past two decades, jellyfish have begun to overwhelm our oceans. If things stay on their current trajectory, we could be headed for a future where the entire ocean is thick with jellyfish. So, is there anything that can keep these gelatinous creatures under control? Mariela Pajuelo and Javier Antonio Quinones take a look at the jellyfish’s most ancient predator.

i love how every bad thing we do to the marine environment seems to harm every species except for the jellyfish
And rats, roaches, mosquitos, feral pigs, etc
@@mission3479 he was talking about marine animals
Climate change and overfishing are the main factors linked to Jellyfish blooms, so if we don't stop depletion our oceans of fishes we will have a jellyfish soup in the future
You’ve never heard of the mersquito before? Hate those buggers
They subsist solely on our hubris and failings. Small wonder, the population explosion
Leather back turtles are also killed when they mistaken ocean plastics for jelly fish. Fishing nets aren’t the only turtle killers.
Sadly, like most endangered or threatened species, the leatherback sea turtle faces many serious challenges. Their nesting sites are PRIME REAL ESTATE. They nest on some insanely cool beaches. They don't nest if there are lights. So development near nice tropical beaches seriously hurts their ability to keep a healthy population going. We want to actually see their population take off.
We can thank places like Playa Grande on the Pacific coast of NW Costa Rica for protecting miles of pristine beaches from development - and from poachers. I was lucky enough to travel there thru my university about 20 yrs ago. We went all over Nicaragua and Costa Rica during a three-week long whirlwind tour of paradise.
The beach was one of the last places we went. I was tired very tired by the time we reached there. We heard a lecture from this cool Biology prof from Purdue. He ran some study down there and coordinated a small army of volunteers and grad students. IIRC, they have something like 20 MILES of beach with zero development.
I grew up in the country, but at the edge of the suburbs in Upstate NY outside a medium-sized upstate city. I've been camping out in the wilderness. i spent summers on the family farm in a more remote area of Upstate. I thought i'd seen the stars, the night sky, but i hadn't until I saw it on a moonless night without a drop of artificial light in any direction for miles.
We had to wait for hours after the lecture. I was tired so i got annoyed like come on, let's just go to sleep. Thankfully I wasn't in charge and wiser heads prevailed. At like 2 AM, we were taken by a local guide far out onto the beach. They were incredibly strict about camera flashes and flashlights. He had the one light - a small penlight with a red filter that he only used a few times sparingly. We didn't need it soon anyway as our eyes adjusted. It was a long walk on the sand. Following directions we were silent. Finally we got to see something I'll never forget: a young female digging a hole and then laying eggs. My eyes aren't the best though they were better then than now and I saw this beautiful animal seemingly in a trance while she dug. She was only about a meter across - so a small one. we kept our distance and a few of us at a time got close enough to see each stage. Her process took a few hours so we all got a good, close view of the magic. I didn't know it was gonna be so amazing.
We did a lot of amazing things that trip, but none matched that. Everywhere we went was amazing but that seemed extra special. It felt like something so few humans get to see.
The preserve had armed guards IIRC to protect against poachers. One of the very rare murders in Costa Rica occurred a few years ago when a local volunteer - passionate about protecting the unique ecology of his country - was killed in relation to his duties protecting the beach. Everyone i met in Costa Rica - especially at the beach - had this amazing easy-going attitude. The truly lived this Pura Vida - the nation's unofficial motto (pure life). It sounded like this young man who was killed was just like that. The type of outgoing, smiling person that lights up a room, that everyone loves, that is so passionate about a just cause that you can't help but get wrapped up. Everyone leaves a place like that with a plan to return. Or to even move there. I did.
I never went back. I know now that I probably never will. But at least I went once. I'd like my tourism money to support their work, but i have none.
LB sea turtles lay hundreds of eggs. usualy about half are infertile - they lay these on top so if a predator (like cats - an invasive species there) come along and dig it up, they get full on the unfertilized eggs.
The ones that hatch are pretty helpless until they get into the water. The scientists there collect the eggs, do their science stuff taking measurements, recording wehre and when, etc. collecting data, and then when tehy hatch, they bring them back to where they were laid and release. They get a slightly better chance of survival bc poachers and predators are less likely to get them. they release the babies at night and IIRC protect them until they get to the ocean.
They say only one in 500 make it to adulthood. One mom must therefore lay hundreds of eggs to replace herself and the male.
The professor from Purdue was optimistic about their rebound. He said that because they lay so many eggs, that there is huge potential for a boom in sea turtles at every hatching. I hope so because those oceans are rough - at least until they reach adulthood, when they're really too big and their hides too tough for predators to want to eat them. Aside from maybe the biggest of white sharks.
he had previously studied them along the Gulf Coast, where the lights from oil rig platforms and refineries scare the sea turtles away. He had some scary data - like one year there were thousands of nesting, then a refinery went online. The next year there were hundreds of nests. Subsequent years got down to dozens. In a few short years tehy went from many thousands to dozens and the agency with authority - either the EPA or the texas department of environmental conservation - were powerless. IIRC, they tried and a federal judge in texas sided with the massive oil companies. It's big business. It's not a wise enemy to make in texas. And this was the early 2000's with a republican in the white house fresh from being governor in TX. A Texan with ties to big oil as POTUS, with a VP with even closer ties. Cheney was like Darth Vader to me then. And even HE divested from his companies while in the white house.
All my plastic waste ends up in landfill, rather than "recycled".
@@richardthomas5362that is sad
@@jonasshiujunhimgsps6078 That's because of high labor and low salary in recycling jobs like plastic. It can get as low as 3 USD per 300 tons of plastic collected. Plus recycled plastic doesn't always come with the same high quality as it is with new plastic because it could be contaminated, and processing and repurifying it involves a lot more work than it already is as it is because different plastics have different types of polymer.
@@jonasshiujunhimgsps6078 Plus businesses love the third part of the Cycle but hate the first two, Reduce(not as much product sold) and Reuse(Less product sold over time), with Recycle being loved as it can be pawned off to a different person that they don't need to worry about.
Jellies are mostly water in content but when they’re breeding, which is a lot of the time, they are super high in fats making them a tasty meal for leatherbacks. They really are incredible animals.
They are bad
@@izdotcarter based on…?
@beccaf262 i assume personal experience
how can you be 'super high in fats' when you're 95% water. that literally makes no sense
metabolism
I went from “WHAT?? Pepper grain sized stinging jellyfish?!?” To “WHAT?! 2-meter sized jellyfish?!”
If you think a 2 m bell is impressive, wait till you hear about the lion mane jellyfish, which has tentacles that can get as long as 100 ft or 30.5 m. This species also has a bell size of 2.4 m.
As a jellyfish myself, I think our population is slipping out of control.
Of course it is😂
Weirdo
A real jell don’t tell
@@kanyemidwest293 I’m transparent.
Eyyyyyy --@@mustafaaalmosawi
I have to say this is so beautifully animated and the background music fits so well. I love how as we humans create problems like hunting vital animals for the eco systems at the same time some of our brilliant minds come up with solutions. Those nets that emanate light that other sea animals can see and avoid is an intelligent solution to save other species.
😊😊😊
"As we humans"👽
I know right ❤
@@Nobody-lz7tg I mean its us humans right or is there another intelligent species besides us?
We already have nets with special pockets in them that eject sea turtles if they get snagged. Also, Jellyfish are not limitless and they are even older than sea turtles yet never took over the world. Fish existed before the reptile and they lived just fine.
For a creature that is 95% water, they sure are a notorious bunch.
OK?
Littledudefromacrossthestreat, water is a very dangerous substance. Everyone who has drank water has died!

thats rich coming from a punk made from 2/3rds water 💧
@@byloyuripka9624 Still way less drenched.
As a jellyfish fan, i also believe they should be put under control
We should ban them until we know what's going on
As a jellyfish, we dont want to be controlled by yall.
As a sea-turtle fan, I agree
As a sea turtle, I would like to live freely so I can eat jellyfish (respectfully)
@@Navaneethkrishnamaru are cheating, jellyfishes gonna receive a temporary ban until sea turtles can return to the game
A 200 kg jellyfish and a half ton turtle? Man the ocean makes me feel insignificant
Wait till you hear about how much blue whale weight. Just remember not to act too surprise, I’ve heard they’re very self conscious about it 😂
That "I like turtles" kid was right all along!
I lived in a small fishing village in Peru and know firsthand how economically challenged, though vibrant those communities are. They absolutely need to continue fishing almost daily, so it's great to see that environmentally viable solutions exist to enable them to do just that.
dont care they are parasites
Damage to the marine ecosystem is especially detrimental to small fishing villages. Once the fish population starts to collapse, so does the local economy.
I've always loved TedEd animation but the info about small fishing vessels is wrong. The highest percentage will always be coming from large-scale fishing vessels. And much worse, they're even harder to regulate.
I love how it began with a simple scientific exploration of jellyfish -sea turtle relationship then escalated to social and political awareness
All environmental problems are, in their essense, social-political problems.
Everything has to be political nowadays
@@StavroginNikolaybecause politics affects every aspects of our lives whether we realize it or not
@@StavroginNikolay There isn't a single moment in history when everything is not political.
I knew it as soon as they talked about sea turtles and it was absolutely necessary to go off on that tangent.
Jellyfish can really adapt! Our crew got on camera jellyfish in a lake in Borneo that got trapped there, so their tentacles evolved and don't sting! And the lake looks like a scene from another planet. There are so many jellyfish living in there, it's fascinating to see the footage.
Got a link to your film? I'd love to see it
This reminds me of the Star Trek movie about the consequences of whale extinction... This was lovely to watch as well as informative.
another important reason to protect sea turtles❤
Some species of jellyfish are edible to us humans and considered delicacies in parts of Asia! They’ve been one of my favourite dim sum dishes since I was a child.
Anything that is alive is considered a delicacy at least somewhere in asia
Jellyfish salad is my most favorite dish to be served as appetizers during wedding celebrations.
Essence energy from jellyfish
@@Makes_me_wonder not wrong lol
I am glad you think they are delicious. Me - No thanks.
Ive been in the mood lately to give away jellyfish, just randomly like in an alley or street, just to those in need of them. Glad to see the earth is producing a lot of them.
As a sea turtle,i see this as an absolute win
The new animator and the music are both unbelievable. If this is a new style and outlook for TedEd, I am onboard. It is sleek yet awe-inspiring.
They have different animators for many different videos
Notice I said "A" new style, not "the" new style
@@benjaminlieberman3932 but they might not continue with it, since they mix up the style with every single video.
Jellyfish is a very common dish over here in China. I'm actually very surprised that jellyfish overpopulation is a thing since it's on almost every family's dining table.
What's the water content? How do you cook it?
@@pierrex3226 I think Goldthread has a video about how jellyfish is eaten in China. I'd post the link, but links seem to get comments automatically hidden or removed on many youtube channels.
I dunno. Is absolutely any jellyfish can be cooked? Even poisonous ones?
@@antonzhdanov9653 No, only some species. Look it up in Wikipedia, it's actually well documented.
In the kettle obviously, obviously.@@pierrex3226
Loved the Finding Nemo quote in the beginning! 😍
Kudos and many thanks for another brilliant video guys!
The animation gets better and better with every new video ❤
Cant believe my childhood source of stock knowledge is still spitting fax
The fact that they are the oldest living creatures before the dinosaurs ever lived, them taking over the world is likely to happen. Not even a meteor can stop them 😭
These animations are outstanding. Thank you.
" A world packed with Jellies." Now I'm starving. 🤤
I wonder if humans can invent a new food as the jellyfish is the main ingredient. 🤔
Are you a sea turtle?
@@aliahmia4420Humans are so crazy for the thrill of discovery so it would not be surprising if they actually did it. ( In the future of course.)
@@lukesams3349yes. I'm a human turtle who slurps jellyfish like jelly. 🍽️🤤
@@aliahmia4420 Actually dishes made with jellyfish as the main ingredient already exist
the knowledge which our education system can't give-
probably cuz they don't want you talking about jellyfish at your job interview /j
So basically its a race between A.I. 🤖 & Jellyfish🪼 for who can overtake humanity the fastest 😅
There's always nukes if all else fails.
The thought of a sea of jellyfish will give me nightmares for weeks. Thanks.
Im so glad my country eat Jellyfish and make delicious Jellyfish lol
Look at how caring that fisherman looks at the end.
I hope this gets viral. To the point where it can influence policy makers. ❤
Seeing Sea Turtles as an unlikely protector reminded me of Gamera.
Truth is, there's not enough turtles out there to suppress the expansion of jellies.
Yeap, that's would be a fact likely for a whole 21th century bcs jellyfish is capable to multiply yearly while turtles takes decades for each generation.
Never were, they aren't never their main predator. But a video about tiny bogues, sardines, damselfish, etc feast on jellyfish when they spawm can't reach a political view.
This is why we need to protect all sea turtles. Without them, you wouldn't even be able to go to the beach.
And when you eat fish you are contributing to the deaths of sea turtles as they get caught in these trawler nets that are left in the ocean. So go vegan and quit eating fish.
The irony is that, the jellyfish are just doing in the sea what humans are already doing on land. And I bet we are increasing and destroying at a faster rate. :(
what if there is a land version of the leatherback turtle? Just waiting for its moment. WHAT IF... 👽
@@K4R3Nif there was we extincted it already
@@K4R3Nwe actually do already have something like that, natural disasters
How am I here so early?
You're not
@@FarisClassicThey are pretty early actually
Mm
U build different that’s why
Yeah!
The starting quote from Crush in Finding Nemo sent me wheezing 😂😆
Meanwhile in Jellyfish-Tube there's a video dealing with the issue of the rapidly growing human population
The easiest way to prevent jellyfish is to carve stones that can whistle and plunge them deep in the abyss, because jellyfish love music!
(For those who don't get it, it's a SpongeBob reference.)
I pray you’ll find the courage to start over. Stay blessed guys!! 🙏🏼
The fact they have such a cute name but aren't cute at all is concerning
Gotta love the Finding Nemo quote in the beginning 👌
Nature is amazing, the balance is magical
This should be the immediate answer readily avalilable whenever anyone asks why protecting sea turtles is important.
Jellyfish boom is indeed a large problem connected with global warming. I was always kinda scared of them and an idea of sea filled with jellyfish seems nightmarish. Though I don't really want all jellyfish to disappear, nature and it's diversity is beautiful but I support protecting of sea turtles as jellyfish natural predator.
Global warming is not a main factor. The main factor is relatively recent (somewhere from 60es progressively with continuation of development till today and mass spread of technology around the world in 80es-90es) intensification of agriculture with mass use of nitro fertilizers. They are vital for better and faster growing of plants, though, washes out from soil into water and from rivers into ocean, where ramp up massively a growth of algae consumed by marine animal life. And jellyfish is just the most rapidly breeding species catching up with explosion of marine plant life growth. Though, global warming definitely helps making their breeding lands wider. And the problem here, that jellyfish is not preferred meal for most marine predators, turtles being likely the only one highly adapted to their consumption. An due to that, in future likely there will be a quite bad explosion in growth of relatively fast breeding predatory fish which can use a jellyfish as a meal, but just in case of hunger, preferring other species as their meal, likely driving them to extinction. And while jellyfish multiplies in numbers on yearly basis, turtles need decades for yach generation to grow.
So indeed, before turtles catch up in numbers, what likely won't be a matter for whole 21th century, we would likely have seas and oceans overgrown with algae forests and stuffed with jellyfishes. Both are notorious for their poisonous kin.
Limiting production of nitro-fertilizers is possible, though, replacements are less natural for environmental cycle, harder to produce, less effective and more harmful for nature while susceptible to lead to the same issue. So far the best angle to solving this issue is better food processing and larger variety of food products in consumption. Bcs, "only" 11% of population suffers from hunger 20 is underfed and around 60% suffers from malnutrition due to bad diet habits mostly inspired by food products cost disparity, while 30% of all food products rot before finding their consumer. So, refrigerating, dried up packaged food processing and reprocessing of expiring products (expiring ham to frozen pizzas or expiring milk into cheese e.g.) should be largerly promoted making it accessible to the most vulnerable economically people solving at least hunger issue.
Imo, limiting access to fertilizers is wrong practice as hurts farming in general, as well as usually farmers in poor countries suffer from it mostly due to shut down of programs aimed to grow their efficiency due to application of modern technologies in their industry. Yeah, big food corporations are totally not pummeling their concurrence....
So much better promoting better food storage, processing and healthy varied diets (a call for vegetarians actually. They destroy planet ecology by promoting only vegetation as food source, so higher need of arable lands (so, deforestation either) and fertilizers, so higher amount of fertilizers into oceans, ruining their ecosystem stability more). We are producing more than enough food for everybody already. We fail to deliver.
Didn't you never wonder all the protection towards the sea turtles, but their numbers can't really increase. Maybe protecting a nest at al costs from natural predators, smooth the sand path for the babies, incubate them outside the beach pick up any baby who runs in the wrong direction, don't leave predators to feast on them all of that isn't really a biological protection of a species which evolve to spend high metabolism to produce thousands of eggs.
@@antonzhdanov9653 I think you have failed to notice that a great portion of the agricultural production goes to feed livestock. So no, vegetarians aren't making the world worse, lol.
Just wait until there are jellyfish that use a plastic casing, then it's over for those pesky turtles.
I love how the quote in the beginning was from crush
Jellyfish: "I fear no man, but that... Thing... It scares me."
Mola-mola
this is why its important to save the turtles!
This is exactly why I keep a whale shark in my living room!

Last year while diving an underwater canyon in Honduras I swam through a jelly and it startled me and I slapped it…… suddenly its jelly buddies surrounded me and stung me. Ruined the rest of the trip.
Great info 👍
Jellyfishes overpopulating entire sea in the whole wide world.
Sea turtle : *"It's free real estate"*
ah yes,jelly fish,the one i though it was made out of jelly in my childhood
love love love how sea turtles are portrayed as an eldridge nightmare (to jellies) by animation :D
Jellyfish haven't made it through all 5 mass extinctions and 500 million years of existence for nothing. They're so adaptive, it's amazing.
The background music I would've loved to hear on this video is...
"The Jellyfish Song" by Caroline Konstnar. Here's the opening lyrics:
"Some say jellyfish are lazy,
but I don't think their lives are all that crazy,
Soft-bodied sea creatures,
showing off their curvy features.."
There are a couple of 'family-unfriendly' words beyond that point that might need to be bleeped out, but it's a great lo-fi tune nevertheless.😊Check it out right here on CZcams.
Of all the things that were tearing down the world now I can add jellyfish something I never considered before gosh darn it
Let me be honest, I don't care about any of these. I am just here to appreciate the art. And its amazing.
i was absolutely not aware this was an issue, damn
Really nice animation!
Before I clicked on this, my initial thoughts were " I thought sea turtles do feed on jellyfish?" 😅
My initial thought was "land could definitely stop jellyfish" my second thought was "mola-molas"
Also the other person is 100% a scam
Your videos are always great, but the artwork in this one is probably the most beautiful one so far ❤
I ate jellyfish in Manhattan, NY 2 years ago! It was delicious!!
what did it taste like?
Leatherback's esophagus is really vicious looking; good thing they're only terrible for the jellies.
What a nice idea - allowing poor people to work AND saving turtles. We need more solutions like that.
TED-Ed how do they eat no more than 1000 metric tons through their 50 year lifespan (18250 days) given that this number of 0.4 ton of jellyfish a day ? Cause otherwise It would rather be like roughly 7300 tons ? Maybe I did not understood, and still I really like this episode thanks to you guys !
No you're right they messed up
Thank you 🙏
Jellyfish translates to “Mother of seas” in my language, Turkish. Well, now I get the reason behind it.
I stopped buying fish years ago, little LEDs aren't going to stop the fishing industrys destruction
I love with the animation ❤
Narrator: Is there anything that can keep these gelatinous creatures under control?
Turtle: EAT THEM!!!!
As someone who loves jellyfish and studying them (my username is literally the phylum many species of jellyfish live in lol), they have been around for 500 million years, and thanks to how we treat our oceans, they will be around for 500 million more.
"I like turtles!" boy was right all along!
Ted Ed is telling us the truth.. through jellyfish. thank you Ted Ed
Make a movie about Mutant jelly fish.
Teenage Mutant Ninja Jellies?
Human activity need to be put under control not the jellyfish. The jellyfish is just a byproduct of our actions
The first part of the video reminded me of another species that is crowding the land...us.
New fear unlocked: Leatherback Seaturtles
Amount of tedex videos i have watched that makes enourmous big problems, about fisherman from two specific town or something is just countless. Keep up the good work lol
An army of cloned SpongeBobs and Patricks would help.
I love how we activly do everything we can to promote harmful things while destroying the things which stop said harmful things.
About damn time
I love jellyfish, they're sooo cute! But they are little troublemakers so it's okay if we support sea turtles that help control jellyfish populations.
That is such a novel solution. Amazing that it actually works.
just searched google and there is only 30-40k leatherback sea turtle left in the oceans...sad
Yep can confirm, I do encounter Tantacool every step in ocean
In Australian prawn trawler nets require *"Turtle Exclusion Devices or T.E.D"s* (sort of like a hatch they swim out )
04:50 - Yay! Theres hope! 👏😀
That could be the theme of an animated movie: a group of fishes protected by one old turtle and one decides they should take part of the conflict beetween their old protector and the Medusa Gang.
It's kind of sad irony that we have sea turtle issues of conservation and them eating plastic, yet jellyfish populations are exponentially exploding. This should be prime time to be a turtle with an all you can eat buffet.
I believe the huge Ocean Sunfish also consume jellyfish almost exclusively.
Yeap, but ocean sunfish gets use of them as their meal just in a case of hunger, preferring hunting another pray over jellyfish. Growing those would devastate ecosystem driving a lot of species into extinction, while turtles chew jellyfishes casually non-stop, preferring to stroll like a sea-cows and amass number of less nutrient ones over more pro-active hunting of something better.
Though, indeed, the issue of turtles, they can't solve issue of jellyfish number explosion bcs they are too slow-breeders, some fishes are way safer bet.
This is one of the first time ever someone who is talking about saving the environment also takes into consideration that ppl living on the edge of poverty like peru etc cant just "stop fishing" and die... and that they cant be the solution when they are only thinking about surviving. Its easy to say u want to save the environment if u only have to stop using plastic bags and turn of ur lights when u leave ur house when u come from a first world country.
me watching this while my paper straw slowly dissolve into my milk to save turtles
