Polar bears are classified as marine mammals because they spend most of their lives on the Arctic Ocean, depending on sea ice for their food and habitat. But not all sea ice is the same. The way ice moves, melts, and forms varies from region to region. The dynamics are so different that scientists from Polar Bears International have divided the polar bear’s range into four distinct ecoregions. The Archipelago, Convergent, Divergent, and Seasonal Sea Ice Ecoregions.
Spread across these 4 regions are 19 distinct polar bear populations. 2 of the polar bear populations are growing. 4 are likely stable. 3 have seen significant loss in the number of bears. The other 10 polar bear populations are a complete mystery. We know little to nothing about those bears.
Polar bears have perfectly evolved to prey on ringed seals and bearded seals, which polar bears catch from atop the sea ice. Seals will cut 10 to 15 breathing holes in the ice and they’ll keep these holes open all winter long. Every 5-15 minutes, seals will surface to breathe at one of the holes or at air pockets trapped under the ice. Polar bears can smell a seal's breathing hole from more than half a mile away. When a seal surfaces… the polar bear strikes.
Polar bear heads are longer and more slender than other bears so they can fit into these holes. Even polar bear teeth are specialized for seals. Polar bears have a larger gap between their sharp, front canines and back molars. This is known as a diastema and it acts like a hook for a polar bear to snag a seal. Polar bear skulls have an elongated crest - the longest of any bear - giving polar bears the strength to pull a seal out of the water.
Healthy polar bears only eat the seal blubber, leaving the carcass for scavengers such as ravens and arctic foxes. One polar bear can eat 45 kg (or 100 lbs) of seal blubber in a single sitting, providing about a week’s worth of energy.
In 1980, there were 1,100 polar bears in the Seasonal Sea Ice Ecoregion. As of 2022 the population was just over 600 polar bears.

Polar bears aren't the only animals affected by a loss of sea ice. Other species like walruses, penguins, and even snow crab have been affected by shrinking sea ice.

These animals are beautiful and amazing! Clever, strong, determined. What a predator! Thanks KP for the video. Like a lot of animals, I hope we can keep them from extinction.
Thank you very much!
@@KPassionate As always, thank you !!!!
Such beautiful creatures! The way the cubs follow their mother around and snuggle up to them to rest is just beautiful. Definitely one of my favorite animals 🐻❄️
Very interesting and informative. You showed that not just polar bears live of their prey, seems birds and arctic foxes (and probably other animals) depend on the polar bears for their food. It would seem to me that the danger to the polar bear population would also pose a danger to other populations as well. Thank you for keeping us informed!
I discovered your channel today. Awesome knowledge being spread in this video. I'm saying good evening to you from my home of NYC.
Sincerely,
Terrell
I’m glad to have you here!
@@KPassionate thank you 💚
They can't bear it any longer 😂.
Thank you for keeping us as up to date and informed as you can!! ♥
Thanks for taking the time to comment!
great video!
I fell in love with the polar bears from watching San Diego Zoo’s live camera of the polar bears. I had always hoped one of the male-female pair would produce a cub. Unfortunately, it was not meant to be; possibly due to the warmer temperatures down in Southern California.
There were some famous polar bear cubs that had to be hand raised by humans in a couple of zoos in Europe. Knut and Siku got me even more interested and hooked on watching them. Now that I am in a different phase of my life, I have not been able to follow the bears’ stories as much. I still follow Polar Bear International on YT though! Love these beautiful but deadly creatures!
The study and footage of the bears on a treadmill was done at San Diego Zoo. That was Tatqiq! SD Zoo is an incredible facility that takes amazing care of their animals. Breeding can be tricky no matter where you are.
@@KPassionate Yup! Tatqiq and another polar bear from the Oregon Zoo if my memory is correct. 🙂 I love Tatqiq and her brother Kalluk. Tatqiq is a feisty one! 😁
Thanks for another educational video. Of all the declining animal populations, I find polar bears the most distressing.
A comment to boost the algorithm - cheers for what you do 😊
Much appreciated!!!
Thank you KP for educating people about these magnificent animals Your videos are so informative So sad that we can watch 100 videos like this but still not take all possible actions to prevent it So sad
Hopefully we can work together to change that!
I never thought I would see the world from underneath an ice bears beautiful snout. Thanks. The experience really moved me. Especially since their population decline is so sad.
Wow I love this!
7:10 Also cool tie-in with this part, there was a ship called the Chelyuskin that got stuck around here and can attest to the fact that this region was unforgivingly cold for much longer then than it is now (though that case may have been a freak occurrence according to some data at the time)
I love bears! All bears! Thank you for educating us.
Any time!
Great details--totally trustworthy.
First comment! :) love animals ❤
Thank you for another informative video. Polar bears are magnificent animals and the human race has a lot to answer for in the lack of care for the planet. I regularly watch videos by Ocean Conservation Namibia - I saw your interview with the team as well - and we really all need to be much more mindful of the devastating impact we have on other species.
I love OCN! We raised over $20,000 for them on one of my charity livestreams!
Very well done with your fundraising😊. Ironicallly, the OCN channel first appeared in my feed last November, presumably because I had been watching several videos of your work with various sea otters - including (but not only) Joey, now grown up, objecting to the pink jellyfish toy😅
Anyway, I have been priviliged to send a couple of donations to OCN since 💙
Thank you for all you do to educate us: if we don't know about other species or our impact on them, we cannot protect them.
I’m from Alabama and the alligators we have here along with the water moccasins make you somewhat apprehensive of approaching riverbanks and lakes you just don’t know what’s lurking out there.
Oh, whoops, it's pronounced 'Bo-fort' Sea. I live near it. Beau is French for beautiful. 🌻 Great video :)
I know I will have to join. Not tonight. I'm old and tired. But you, are gifted. I will subscribe soon I am sure. I once studied Oceanography, loved it, and then got caught up with making money. Like most of us.
Seals probably think this is a good thing.
Unfortunately they are also suffering from the lack of sea ice. It’s where they raise their pups and the basis for the entire arctic food chain.
lol. I forgot I was subscribed.
Im commenting nine words to boost the algorithm
I feel like the Russian polar bears could potentially adapt to life on land. Especially as much of Siberia lacks infrastructure and roads, in many places, and some areas have no human inhabitants still. Of course, that also makes it difficult to know these things for sure. I also wonder if any of the Russian bears have interbred (grolar/pizzly bears) with brown bears on land, similar to the anomalies we’ve seen in North America. Random interbreeding is likely a result of the extended time being spent on land by polar bears. It’s possible in siberia, at least, they’ve even adapted to hunt land-based prey, muskox, reindeer, etc. There are lots of Russian reports of polar bears invading small villages during certain parts of the year… so I wonder..
In my opinion, climate change is a dicey subject. With 8 billion humans on the planet, yah we change things for sure. An understanding of the natural cycles of the earth is imperative. I am enjoying your science based sharing.
Can we make artificial platforms>? Seals would come bears would come? Or no?
Seals would not use them. They need sea ice. In addition, the scale at which you are talking about would be impossible. Finally, sea ice is the only place that can grow sea ice algae which is the basis for the entire food chain in the arctic.
It will be great to know what the foundation is actually doing. From the page it seems they are keeping statistics, not helping the bears. Climate change can't be attacked just by lowering Energy consumption. In the case of cities we should create infrastructure to prepare for the disasters to come, and in the case of endangered species, even if we don't like the idea, is time to start researching interventions.
According to AZA: "PBI is the preeminent resource for polar bear information, scientific, and educational resources, and has a measurable impact on the preservation of polar bear habitat. PBI works with the leading scientists on research projects such as population studies, capture and release telemetry studies, and husbandry, nutrition, physiology, and human-impact topics and PBI's wide range of educational projects inspire, inform, and empower people to make a difference by reducing carbon emissions and motivating others to do the same."

They have a 100% charity score, earning it a 4 star rating.

Keeping statistics and monitoring bears is vitally important. In fact, it was their activity data that led to the bears being listed as a threatened species.

I will get in trouble now. It seems that is what I want to do nowadays. I keep seeing videos about what we can't do, or commentary the same as. But yet we have drones all over our skies by many countries keeping track of all other activity, especially to maintain some military advantage. IF, we found a better purpose for technology we could in fact monitor the entire planet. That is happening now of course, but it is for monitoring people. Not the planet. And now I must delete my account. Which I won't. I do love your channel.
We are so fuct...
Polar bears, along with other Artic animals, should be relocated to Antarctica.
So so sad
Humans, what destructive creatures we are. We are on a downhill trajectory, and we just keep sliding, obliviously.
the "hero wars" ads are getting so repetitive and intrusive it's bordering on harassment - I have no interest in "hero wars"
I just read that Svalbard had no sea ice this last winter and that there are different plants, animals and fish there now.
They didn't mention polar bears. I see now why they didn't. There weren't any polar bears.
There isn't anything for them to eat and survive.
It just makes me furious that supposedly there isn't such a thing as climate change. And it's the fossil fuel industry that is paying politicians to say this. I never thought that I would say those words.
Please, vote out the mostly Republicans who are doing this to our planet. Vote for people who will do something to save our species and the polar bears.
If you are living elsewhere in the world, simply voting for people who acknowledge that it is we who must do things should do the trick. For instance, the "Canada" that is mentioned a lot. Don't live there anymore so don't know the names of the political parties or what they say they believe in. But, I am certain that the names of the parties are not the same as in the USA.
I get your drift, though. 🙂
The effect of electing 45 set conservation and the effect of climate change back immeasurably. But then the idiots who vote for him don't watch videos like this!
Lmao. But I bet you're a big fan of people like Taylor Swift.
My friends and family don't work for the fossil fuel companies, so i dunno how talking to them about climate change will help.
Despite everything that subject matter experts know, we haven't even slowed down the rate at which we are increasing our carbon pollution. I don't like being a negative nelly but so long as BP/Exxon get to choose who we vote for, climate change isn't going to be addressed.
Support Georgia (the country). Vote Democracy. Vote Ukraine. Vote Biden. Vote Blue.
Isn’t Georgia an ally of Russia?
@@Pub2k4 , Georgia (the country) is looking to join the E.U. and N.A.T.O.. It's been working on it's join E.U. pre-reqs I do believe. No one I know from there considers Russia an ally, but an invader and enemy to their homeland. Russia is currently occupying 20% of the country, since 2008.
