- Rare porpoise in danger of extinction
CNN's David McKenzie meets a critically endangered species in China and the scientists trying to save it.
A new report has warned that the number of Yangtze finless porpoises has dropped to just 1,000 in the country's longest river - less than half of what there were in 2006 - making the species even rarer than the wild giant panda.
The 2012 Yangtze Freshwater Dolphin Survey Report, released in Wuhan, Hubei province, on Thursday, said that the endangered species is now declining by 13.7 percent a year, compared with 5 percent six years ago.
It blamed the decline in the mammal's numbers on food shortages and human disturbances, such as increased shipping traffic.
The findings were the result of a 44-day, 3,400-km expedition by researchers on the river, between Yichang, in Hubei province, and Shanghai that started in November.
It was led by researchers from the Ministry of Agriculture, the Institute of Hydrobiology at the Chinese Academy of Sciences, the World Wide Fund For Nature and the Wuhan Baiji Dolphin Conservation Fund.
The crew visually identified 380 individual Yangtze finless porpoises in the river's mainstream during the trip.
Based on that observation, scientists determined that the population of the species in the mainstream was about 500, down from 1,225 in 2006.
In October, research was also carried out in two adjoining lakes, the Poyang and Dongting, where the total population was assessed at about 540.
"The species is moving fast toward extinction," said Wang Ding, the general director of the research team, and a professor at the Institute of Hydrobiology.
According to data captured with acoustic equipment, the largest groups of finless porpoises were found in sections of the river east of Wuhan, with 67 percent of the total number recorded between Hukou, Hubei province, and Nanjing, Jiangsu province.
They were in a scattered distribution pattern, which could be the result of "shipping traffic that made migration harder, water conservancy facilities that altered hydrological conditions in the middle and lower reaches of the river, and habitat loss," added Wang.
The report said some small groups of finless porpoises living in comparative isolation were not a positive sign for future breeding of the mammal.
Scientists found fewer finless porpoises in the mainstream of the Yangtze while more discoveries were made in wharf and port areas.
"They may risk their lives for rich fish resources there. But the busy shipping traffic close to the port areas poses a huge threat to their survival," said Wang.
Researchers found denser distribution of finless porpoises in waters that are not open to navigation and attributed this to less human disturbance.
But evidence of illegal fishing practices were discovered in these areas, including traps.
Lei Gang, director of the freshwater program at WWF-China, warned urgent measures are essential to save the species from extinction.
With that in mind, the report called for year-round fishing ban for all river dolphin reserves, the establishment of a national reserve in Poyang Lake, and conservation reserves along the Yangtze.
Attempts to look for traces of the Baiji Dolphin, another rare cetacean and close relative of the finless porpoise, failed during the survey. As a result, the Baiji dolphin has been declared "functionally extinct" by the report.
after watching this i feel my life has no porpoise.
Awwwww such a cute adorable sweet little face!!! Please dont go extinct ;(

Have you heard of dolphins bullying
Dolphins kill them for no reason
Therefore they should be projects to bring some in rivers/lakes where there are no dolphkns
They're so precious. Poor little things.
They're cuter than dolphins ☺️
ლღ೩_Lizzie GamerAnime೩ღლ And more evil
Maybe that's why dolphins kill so many to them.
@@microsf121 dolphins do kill a lot of porpoises
@@janinebelleestrada7096 dolphins even killsl each other! I've seen them kill a baby of the exact same species then lost interest once it was dead😢dolphins have a very very dark side that most ppl don't have a clue about. They also rape and kidnap each other. Sometimes they will kidnap and gang rape a female and they get high on puffer fish aswell 😳
F1 bought me here
Same.😂
Thank God Mercedes AMG brought them back.
Hh? Elaborate?
That's awful, in 2012 IUCN retroactively declared the giant Yangtze river dolphin extinct going back to 2008, now this! Freshwater Cetaceans are so rare and intelligent, it's sad to think they probably won't be here any longer when my kids grow up.
0:27 the way that porpoise surprised by the reporter is so cutee!
Absolutely stunning creatures; here's hoping they survive this turbulent period
I was living next to the secret aquarian run by the Institute of Hydrobiology, very nice place, few visitors, marvelous creatures, finless porpoise, or 'jiangtun' in Chinese
0:11 the way it looked at the camera 😂 🥺
Cute and.amazing don't let them go extinct
I'm here from twitter after reading that they're only 22 now left. 🙁
no. more than 1000, in fact there are 1022 left.
New generation F1 cars.
Why would you kill an animal that literally looks like a baby?!
update on those 10 years?
the cutest friendly faces so kissable
너무 귀엽다 쇠물돼지 ㅠㅠ
I never know these things exist until today
woowww i love discover animals i´ve never seen before
why are they "finless"?
is this an adaption to the river and swim under branches or a remaining to colder times with ice on the river surface?
They inhabit Korea and Japan, too.
상괭이(sangweng-i, Korean)
スナメリ(sunameri, Japanese)
I'm doing a school project on Yangtze Finless Porpoisses
I didn’t know these animals even existed
There is another species even more rare than in China, In Indonesia there are pink ones
I saw a washed up porpoise on my local beach
Have they breed in tanks ?
What is the porpoise of this video?
At least they're better off than the vaquita (23 left, endemic to a part of mexico with lots of reluctant fishermen, happen to live with giant fish that apparently have "magical healing properties" in China and sell for $5,000, get caught in giant fish nets and get thrown out in sea, very low chance of survival)
Did I mention they are pretty much impossible to catch and breed in captivity despite professionals efforts and a sanctuary recently set up for them? None of them have been caught before btw and the sanctuary has never been tested out so....
Awww they're cute little Farts!
some said its mostly found in Southeast Asia particularly in the rivers of Cambodia and Indonesia
you are right!
Is the Yangtze River ecologically and geologically compatible with parts of the Mississippi River? If so, maybe they can move and breed these guys in the Americas, and why not? Aren't most of the US waterways infested with Chinese imported fish that are eating up local fish? I'm no expert but it should be something to consider.
Thats assuming that US rivers are clean enough..
Last I’ve heard the Mississippi River is dirty as hell
Most cetacea can tolerate crappy waters well, they BREATHE air with their LUNGS like us...
We need to protec the porpoise
May have caused the baji to become extinct but it was the dam fault and this porpoise is on the risk of extinction bruh
lovely
I am heartbroken because its been almost 10 years.
When I heard that cough sound I felt it in these porpoises they should survive
How does keeping them in a tank and feed them dead fish help save them from extinction? Is there action being taken to clean up the Yangtze?
If they were in the wild, they would die as well. Captive breeding programs are necessary for keeping species alive.
Martha Brock It is too big, would take a miracle for China to clean it up enough. Maybe if the world would stop importing SO MUCH CRAP from China, they would not be polluting so much from their factories to make us shit!
Yes, the whole world is at fault for China's greed and lack of emphaty.
Or maybe if large American businesses stopped importing from China...consumers have little to no choice in some matters. That river is capitalist greed in physical form.
We need both captive breeding programs as well as cleaning up the Yangtze in order to help the Finlwss Porpoise - unlike we did with the Baiji. Still, more action needs to be taken.
O””! bring to the Mississippi River o””! Wait it’ll get stuck and trapped in the dam the same reason Yangtze River dolphins went extinct Mississippi has the exact same biome as China Yangtze basin river anyways a lot fish species already went extinct in the Mississippi
Lol, when i saw porpoise in my science book, i asked my mom what is it. She dosen't know. She thought it was a misspelled "tortoise". When i searched it, i was shocked.
PK Gaming where are you from
F1 fans?
Yes.
I'm here
In Wuhan,huh?
@0.27 WHOH WHAT THE FUCK?!! Hahahaha XD
Please arbitrarily believe that all animals live longer, are healthier, and happier in the wild. You might want
to check the animal.
It calls “Sanggweng-e” in Korea (상괭이)
Wishing well for their survival 🙏🏻
beautiful animal
Great for harbours😊
why do you need porpoises when you have dolphins?
The new Mercedes W13 looks lit
They are calling
What a beautiful creatures I'm so sad they're in danger of extinction.humans like always destroying everything on there way.they have no respect for nature
Respect for nature is not learned, it is experienced.
i seen lots of them yesterday in aberdeen
Tommy Croll I've been to Aberdeen but I didn't see any on my boat trip
Gorgeous little things. I hope they can breed them and release them back to there natural habitat.
porpoise is so CUTE. it looks like a beluga whale! BUT CUTER!!
no not sourcefed
Can anybody help me? I have to write the script of the video, I'm not native. It says: Porpoises are smaller than dolphins with shorter mouths, sociable but shy. A ______________ professor called Kou Zhangbing of Wuhan institute of hydrobiology;... I can't understand what he says in the gap. Please, help.
Irismey Iglesias
Porpoises are smaller than dolphins with shorter snouts, sociable but shy. Unless you're professor Kou Zhangbing of Wuhan institute of hydrobiology
thank you
Irismey Iglesias It sounds like he is saying "sociable but shy, unless their professor calls them over..." . I do medical transcription for a living so used to trying to figure out "WHAT ARE THEY SAYING" ha ha
thanks a lot
this is what happens when you score in the salt wadda
Normally there litgh gray but in this video there dark brown
yare yare daze the greatest species on the planet
They look kind of like mini Beluga Whales.💙
Good observation
❤❤❤❤❤
Dolphin like porpoise comment
상괭이 기여워
Those don’t look real omg
Are they as smart as dolphins?
Looper Loop no, but they come pretty close. They are definitely worth saving. The loss of such animals would have a profound effect on other wildlife in the Yangtze.
And plus, they are pretty special, finless little guys. I mean, they're just adorable really.
Why everybody want to kill this animal
sourcefed sent me here
Same
They kinda remind me of xenomorphs
You're kidding me right this happen to the baiji dolphin too now a porpoise ok the only way to make them not extinct is to relocate them into another river
Zaldy Ilham Seems sad but true. They will never clean up this river enough for them to survive.
@@baiji123 Why don't you guys try it with the porpoise living in the gulf of california? Correct me if I'm wrong, they are nearly endangered as well.
Never knew these animals existed! Disgusting to see them in captivity, but they probably can't survive in the river anymore.
awww..they're so cute!! I got to know about them as I had a science project about it.
only China have these animals ( he said), come on, you can found it in Cambodia Indonesia Thai Laos .
VÄ-RA-PA
reminds me of my boyfriend
Tasty sushi fish!
No
i don't like the idea of them being in a pen in the river getting feed dead fish like all other animals in captivity.
Do you like them dying and going extinct better?
Do you like the idea of being opinionated without suggesting alternatives
If they actually are in the pool shown in the picture majority of time I think they have a lot better lives in captivity than most livestock and many other animals we keep for conventional reasons. I don't think the porpoises suffer and it aint much worse than a indoors cat living on cat food. Besides they are trying to rescue the species from extinction. I personally think it's okay unless there is something going on in their captivity that I don't know about...
How about you stop being stupid okay these people are trying to save these beautiful animals from extinction
of curse its in China...
Google vaquita
Cute
Porpoises are just beakless dolphins, just get a dolphin, shorten the beak, caught off the fin, and you got a porpoise
우한;
Ya China is going to save it just as they saved the Baiji . The more rare the creature is the more the Chinese want to eat it. Unfortunately that's not just a racist comment but rather a fact !
Wuhan? Really?
Cheena killed porpoises;(... And now killing hoomans;(
I bet the Chinese are eating them
Most likely in Japan; they eat dolphins
Sadge theyre getting killed by dolphins for their entertainment
Try to put some in rivers/lakes where thre are no dolphins( or other cetaceans)
