Terrific video! I've been a commercial diver since 1959 and have witnessed a huge change and not for the good. This educational video is exactly what every diver needs to see. Well done Khaled bin Sultan Foundation!
We've Got Trouble and I have to amdit that Game Freak made it very accurate to it real world inspration from the typeing right down to its destructive coral diet (or in pokemon's case, destructive Corsla diet) bad pun aside, its always cool to see Gamefreak make Pokemon that take inspration from seldom known animals, plants, mytholgical creatures, etc

Crown of Thorns Starfish Crisis - Take 2 In a few weeks, our science team is headed back to the Cook Islands, where we witnessed (and cleaned) a massive crown of thorns starfish outbreak while there on the Global Reef Expedition in 2013. We're headed back to see how the reefs have recovered from this voracious and incredibly fecund coral predator, survey the crown of thorns population on the reefs, and take dna samples of the starfish to see if we can identify where they came from and how they reached these remote reefs.

I love the video it is very informative :) I am doing a school project on COTS and was wondering who I would need to email to ask for permission to use small parts of the video in my school video project, I would only be asking for permission for small visual scenes (no audio) and of course referencing included. Thank you
The venomous thorn-like spines that protect this starfish are the least of our problems - this species is destroying coral reefs in many parts of the world due to an imbalance in the oceans - find out more in this video from the Khaled bin Sultan Living Oceans Foundation. ua-cam.com/video/-ardrFZuFkU/v-deo.html
One of the most common natural disturbances we observed on the Global Reef Expedition was the outbreak of Crown-of-Thorns Starfish (COTS). These voracious coral predators can completely consume the coral on a reef. The reef ecosystem can take decades to recover from this type of disturbance. COTS outbreaks have been linked to pollution and overharvesting of its top predators, allowing these animals to multiply into unmanageable numbers.

Deadly Starfish Eats Coral The venomous thorn-like spines that protect this starfish are the least of our problems - this species is destroying coral reefs in many parts of the world due to an imbalance in the oceans.
I'm sorry, but i'm not really good in english, so i did not understood, why the starfish died in fresh water. could somebody write down what they said as an answer so i can translate it? That would be very helpful Thank you, for that informative video!
Now that our BIOT mission has wrapped up, you may be wondering what we are doing next. Next week, our science team will be headed back to the Cook Islands to study the Crown-of-Thorns Starfish, a voracious coral predator.
Hi Sir, I am Mike Salgado, a journalist from the Philippines. i am currently making a report of COT outbreak in our area. With this, can we ask to used some of your clips above to show more about its characteristics. We'll put CREDIT of your video. Thank you so much in advance. :)
Yesterday i went to the sea and this thing were just at the start of the shore..my mom told me to see what is it...i took a stick and touch it...i found that it was not venomous nothing at all...i held it on my hands...it started walking too..i did not bother! Today my mum were watching some videos on youtube and she saw that it was the toxic starfish that i held on my hand dudeeee😭😭😭😭😭had i known i would have never ever touch it
Good eye! But in this video those are COTS scars, which do look a lot like bleaching. The white patches in this video are from from where crown-of-thorns starfish ate all of the living coral polyps, leaving only the white calcium-carbonate coral skeleton behind. Bleaching also turns the coral white when the corals loose their zooxanthellae, the single-celled algae that live inside the coral, and if the coral polyps die. Once the corals are dead it's hard to tell the difference, but COTS scars tend to occur in patches (a trail of death-by-starfish), while bleaching trends to affect similar kinds of coral across the reef.
@@LivingOceansFoundation woah thanks for clearing that up! I've learned about zooxanthellae and the crown of thorns starfish in Biology, and I was kind of concerned :)
harlequin shrimp. all they eat is starfish. and 1 of these tiny shrimp will eat one of these starfish a week. and these shrimp are indeed tiny. they will take arms off and let the starfish live if there is not a big enough population. but if the starfish population is big enough. harlequin shrimp will destroy them. just sayin
Yeah, and wolves are deadly too. We saw the adverse cascade effect removing them had on ecosystems, why repeat that? Wishfully the "villainous" COTS were relocated, but this report says they were simply killed....
pikapals41 Crown of Thorns are an invasive species of starfish to the area the video focuses on; because of that their natural predators are relatively few. This allows them to outpopulate the local species, preying on other organisms that haven’t adapted to their presence, and endanger the biodiversity of the region
The crown of thorns comes from the bible when Jesus died they placed it on his head which punctured his head and made his head bleed.So he died on the cross but then rose again after 3 days.Do you guys see the similarities 😇 -ten year old Isabelle
If you don't get it think about it this way Jesus is the beautiful coral and the crown is the starfish.The pain and the crown (the starfish) killed Jesus (the coral). But then after three days (decades for the coral) Jesus rose again (the coral reef healed after a few decades). Even though the star is like the pain and the thorny crown I still think this is a cool type of starfish even if the starfish can wipe out a whole species if it's not stopped.God bless you 😇👼👑Bye! -Isabelle

So these are what Mareanie and Toxapex are based on...
Just as frightening in real life as they are in the game. Those poor, poor Corsola...
Hence why we need a lot more Bruxish in Alolan seas.

Now I get why Bruxish is a psychic type.... dat Psychic Fangs tho. bye bye toxapex
I always gotta thank pokemon for introducing me to new animal species..
I knew I'd find someone mentioning toxapex

The animal that inspired Toxapex is scary, lovely and awesome
TOXAPEX

Oh hey
MunchingOrange! I came here because I just hatched a shiny Mareanie and wanted to learn more about "COTS".
MunchingOrange indeed it is
Pokemon
I guess Toxapex is OP in real life too...
Who else is here after discovering the basis of Mareanie and Toxapex?

Can it kill human by its toxic?
It's not a good thing to kill an animal for doing what comes naturally to it

So a Toxapex's predator is a Toady Bloyster?

Ich auch.
Thank you for using SI/metric units
what would happen if you accidentally walk on this cots? are there any special medical treatment? is this deadly to humans? thank you.
very nice video!
Is there no way to engineer a kind of coral that has a faster regeneration process through DNA or some other genetic alteration?
Really interesting thanks!
Thanks so much!
these are really cool! I love sea stars
So, this is what Patrick eats if he doesn't get a Krabby Patty!

I had to watch this for school and damn this really is a Toxapex
very interesting ty
Where are these coral reefs located?
I read somewhere, if you bag them up they get stressed and release their eggs as fast as within 10 seconds is that correct?
Why is it so funny when he says let’s watch cots in action? 😹
lol...corals need good clean water? not going to happen with us humans around. messing things up without even trying to!
wow! who knew elder maxson knows so much about starfish
This is what the octonauts owner caught and made The Ouctonauts & The great barrier reef
Y'all need to get some large guard crabs up in there
the cots are then processed into clif protein bars
I'm a scuba diver and would be happy to help
This helped me on my homework
Deadly Starfish Eats Coral
The venomous thorn-like spines that protect this starfish are the least of our problems - this species is destroying coral reefs in many parts of the world due to an imbalance in the oceans.
Where I live at my local Inlet people take them by the thosands and add them in with Giant Tritons, It's pretty fun to watch :3
I think i saw this on octonauts of that crown of thorns starfish eating the coral patch
show demais parabéns
Animal does what it's always naturally done. Humans: "let's kill it for eating"
I'm sorry, but i'm not really good in english, so i did not understood, why the starfish died in fresh water.
could somebody write down what they said as an answer so i can translate it?
That would be very helpful
Thank you, for that informative video!
It cuts off their oxygen and they suffocate.

Why this thing is created
old coral replace by new growth is a good thing
You stupid af
*is it just me or is this making me extremely uncomfortable*
Many comments are from pokefans finding out the mareanie part eating corsola, a mareanie try to bite me XD
patrick, can you stop eating all the coral?
sounds like humans
That one comment on gnoggins video
Wow
hurry up snails were you guys at😣

Good Day team!
Do you want Galarian Corsola? Because that's how you get Galarian Corsola...(-_-)'
Inject it with vinegar
I still don't get what the star fish eats
+Arianna Pagan coral... it clearly said.
Fuck this thing man! It kills everything!
In conclusion, cots are jerks. Let the fishes you eat them eat them
Soo much l prayer
Patrick's cousin?
so dangerous ooops
Yesterday i went to the sea and this thing were just at the start of the shore..my mom told me to see what is it...i took a stick and touch it...i found that it was not venomous nothing at all...i held it on my hands...it started walking too..i did not bother!

Basically aptasia but a starfish lol
Mrbeast would hate that starfush cuz of teamseas
Just let nature take it's coarse!
I belive Giant Tritons are there only predator

We should not be throwing gunk and junk in the sea
crown of thorns are there for a reason
Yes, but if their numbers grow too large they can wipe out entire coral reefs in a week.
Who the hell dislikes a video like this?
I d k
POV: your here because school told you to
Yes.
this is a problem i classify as unfixable seeing as how FAST they reproduce
They directly stated that human activities are boosting their reproductive capacity by giving their larvae an abundance of food.
imo if its a natural animal leave it be
The basis of the worst Pokemon ever to have been created
wow..... Thorn starfish are glutton assholes.
Just like Mc Donalds :V
I literally cringed watching this
harlequin shrimp. all they eat is starfish. and 1 of these tiny shrimp will eat one of these starfish a week. and these shrimp are indeed tiny. they will take arms off and let the starfish live if there is not a big enough population. but if the starfish population is big enough. harlequin shrimp will destroy them. just sayin

Coral killer 🥸
Doing this for school work but it's boring 😴😂😴😑
just let nature do what it need to do geez
you guys sure seem to villainize these poor creatures...
pikapals41 you watched the video right? Fuck these things, sure its not their fault but fuck these things
i. You act as if humans are not animals, as if we are some higher power inhabiting this world, thats *dumb*
i. ever consider maybe our disrupting of species such as COTS is nature?
