Sea otters once roamed the entirety of the coast from California to Alaska. But where did they come from? How did these adorable animals evolve into one of the most important animals in the ecosystem? How did they become endangered, how they recovered, and what does their future hold? A marine biologist answers these questions, and more!

The first sea otter wasn’t the clam eating sea otter we all know and love. It was Enhydra Macrodonta, or the large-toothed sea otter. As the name suggests, this otter had large, robust teeth that were significantly larger than the dentition of modern sea otters. Like most Pleistocene megafauna, the large tooth sea otter became extinct sometime during the last ice age. Around 25,000 years ago. Giving rise to the modern sea otter. Who first evolved in the waters between Russia and northern Japan before spreading around the Pacific Rim all the way down to the Baja peninsula.
This is around the same time that the indigenous peoples of North America are believed to have crossed the landbridge connecting Asia and Alaska. And sea otters played a very important role for many maritime indigenous cultures such as the Haida of Haida Gwaii and the Aleuts of the Aleutian Islands. Many of these cultures have strong animist traditions full of stories and legends where sea otters were considered kin to humans. Many anthropologists attribute this to the sea otter’s almost human-like behaviors. Such as the way they use tools, clap, hold hands while they sleep, and even the strong bonds formed between mothers and pups.
Unfortunately, this is where the “explorers” come in. Specifically, German zoologist and explorer Georg Steller who “discovered'' sea otters in 1741 when he was shipwrecked on an island in the Bering Sea. Most of his crewmates died in that shipwreck, but the survivors, spent the winter hunting sea otters. They returned to Russia with over a thousand pelts and were able to sell them at exorbitant prices. They were so profitable that British Explorer James Cook referred to them as “soft gold.” This set off the “Great Hunt”... also known as the fur trade.

All of the sea otters in this video were rescued as pups after becoming separated from their mothers. Each otter was deemed non-releasable by either the Department of Fisheries and Oceans Canada or the NOAA in the USA due to the fact that they lacked the necessary skills to survive in the wild.
Special thanks to my fellow marine biologist, Jessleedb, for providing me with additional footage of Joey the Sea Otter.

Thanks KP. The part about the greed of humans is hard to hear but also necessary because we never seem to learn. Thanks to all the agencies who rescue and recuperate these otters. Joey and the other seven of his ‘family’ are wonderful and they help us remember how important it is to love each other and all animals. Thanks again KP and Doubleagent xx
Like many of hundreds of people Joey got my through last year watching him and helped my anxiety watching him grow everyday. Always loved otters but never knew how much sea otters were so amazing and have educated myself and learnt so much from these beautiful mammals. Joey brought us together last year when there was so much doom, Thank you KP for all the updates and videos, love your channel.
Thanks for adding English subtitle!! I’m a English learner so it was sooo helpful!!!🦦
I'm so glad! I have been experimenting with it. Hopefully it was mostly correct!
@@KPassionate it provides access for deaf/hard-of-hearing people from predominantly English-speaking countries/cultures too.
RUclips got rid of Community Captions in September 2020, which would have allowed users to caption for you. But please keep it up if you can, my mom and me are both HH and have been consuming online otter content since the pandemic started.
KP and double, this was excellent! As much as we keep learning about sea otters, there always seems to be more. Thank you KP for everything you do to raise awareness, and to take care of “our” eight buddies!
Amazing episode!
I love it too!
Ooof, that was a hard one to watch but so, so important. Another important reason to move away from fossil fuels and towards more sustainable energies. Also fur trade is gross. Thanks for the great episode KP.
So true! Thanks for watching!
I clicked 10 times the like button, should be 84K instead of 84 because the content is so good, I learnt so much!! Funny fact, I discovered sea otters with that emoticon on my iphone!! and became intensely in love. I even call my gf, baby otter now (= Loutron in french) :D. My dream would be to see one sea otter, apparently in europe there is only one couple in UK. I have to go to the US/Canada, it is planned. Thanks a lot KP for the videos, you have the best otter videos for sure! Of course it is impossible not to love all other marine mammals too :D
Are you in France? If so there are 3 sea otters in Brest Oceanopolis aquarium. I spent a great day there last July
@@wendyinthegarden523 Brest really?? how could I have missed that! Yes I am french but I live in Norway, but I go to France regularly. I have never been to Brest in my life, but I think it is now the time!! :D Merci beaucoup for this info!!
@@youdj_app One of the things I love about this channel is the community, and how they're helpful to one another. Enjoy the otters when you get the chance.
Wonderful and instructive video. Thank you for reminding us of the importance of caring for sea otters and other animals. Very good job KP
Love this! Perfect for Sea Otter Awareness Week! Learned a lot too. Thank you so much! P.S. Q and TazzyLina May are absolute cutie pies! And Queen Katmai is sooo pretty!
You are so welcome! Lots of great content planned for Sea Otter Awareness Week!
Wow.... So much informations. Thank you so much for sharing 🙏❤
You are so welcome
This one made me cry! Thank you for continuing to provide us with this content and for bringing awareness to our oceans and it's inhabitants.
A great „history“ deeper dive. As always excellent narrated by KP and excellent edited/filmed by doubleagent. Thanks for the links to the further information.🦦👍😍😀🥰
Thanks KP, as always very informative!!! So sad the way greed affects soo much in a bad way!!!
such an inspiring video! it gives me so much more motivation to finish my marine biology degree so i, too, can educate people about the importance of sea otters and other marine life! you're one of my biggest role models, KP! thank you and keep up the fantastic work!
I look forward every Deeper Dive video from you. Although my favorites are about the Sea Otters (especially appearances by Joey, Tazlina, Quatse, Katmai, Kunik, Mak, Hardy and Rialto), I enjoy all the other marine mammal videos and have learned a lot. Thanks for your hard work and please keep making more videos.
Very well done and an interesting topic. Important to know about, even the hard facts are important to acknowledge.
The editing is amazing! And you have a very good voice.
Thanks!!! 💚
Much appreciated!
Amazing and educational episode! Thank you KP!
I always learn so much from your Deeper Dives - thank you !!!!
Wonderful and informative KP, thank you!
Thank you KP amazing information to share, learned a lot today!! 💖👏
Glad it was helpful!
And Joey is blissfully unaware of the attention and love that he has drawn to 8 sea otters. Each with their own personality
Joey was the one bright spot of 2020.
Thank you KP. Very educational.
Excellent episode, more and more complex 👏
Thank you KP! Amazing episode. Always learn so much!
Glad to hear it!
Great video, KP. We may have to swing by the aquarium this weekend :)
Fascinating facts as always KP and the scenery amazing ❤️😍
THANK YOU..!! ..for such a well made..in depth and very thoughtful doc… 👍👍 ..I really appreciated that you didn’t rush thru all these fascinating details …. Things really need to sink in and you answered all my questions and revealed so much more besides….This has been an important watch for me….🤔❤️
Wow that’s awesome! This is an older video that doesn’t get many views and very little praise lol. So I appreciate you taking the time to comment!
great video with so much important information! And sea otters!
Terrific channel! Terrific episode! I always learn so much!
Absolutely love all your videos on sea otters. You are certainly living the dream!
I only have 1 tiny issue.. it was hard to make out some words because the music was a tad too loud. Other than that it's perfect. 🥰 Absolutely love the background scenery.. so beautiful there
Thanks. Let me know if you feel we have gotten better at this in our newer videos. It’s a learning process!
A beautiful video, otters and other mustelids are so important to me. I wish more folks cared but with these efforts I hope more do, this is awesome content, thank you so much for all the effort
Super episode! Thanks for the history lesson on our furry friends. 😀
Amazing episode, like always. Love your content. I don't think anyone watching your channel doesn't know who the world famous Joey is, lol
That is probably true hahaha
So awesome! Great and informative video.
Omg the history lesson broke my heart. 💔😥💔
Side note- In the end, an otter was pulling fish out of a body pocket. Do they have some kind of marsupial pouch?
They have a lot of extra skin that they can use to store snacks!
FEED THE ALGORITHM.
SPAM RUclips WITH OTTER CONTENT.
Were sea otters some of the first protected species in the US and Canada?
I believe so! The Fur Seal Treaty of 1911 was the first international treaty to address wildlife preservation and it protected all fur-bearing marine mammals like seals, sea otters, and sea lions. The US didn't introduce an endangered species act until 1967.
@@doubleagentxv120 thanks
They’re on their way to become seal 🦭
🤔 Pretty sure a dog just loved a fish a little too much, and this what we got. Same way we got platypuses. Duck plus...beaver. Thats how biology works, and no one can tell me otherwise. Slam two animals together, you get a new animal. Same as people.
1 thank you for not showing a giant river otter they are horrifying
2 this video was so informative thank you so much for this
3 always eat the urchin
4 fuck oil
5 Bless King Chonk
To be honest, I never really cared about sea otters until Joey came. Thank you for this. I cannot believe indigenous people were killed just to hunt sea otters. 🥺❤🦦
Love the logo! 🐾
I'm glad you are enjoying the otter journey! haha
I’d known about the fur trade but not about the enslavement and deaths almost all the Aleuts! Horrifying and we need to know - thank you
Thank you for sharing. It’s important for all of us to understand the history of the sea otter; especially the horrific parts. It’s terrific to know there are others like you who care enough to do the hard parts so all of us can enjoy and get to know these incredible and cute animals! Thank you!
Your videos are so informative and wonderful. Thank you for all you do
Glad you like them!
We need moar sea otters! And more cute otter content is perfect for sea otter awareness week!
More to come!
Great video KP and Doubleagent. Good background to have before going to VanAqua today.
KP, I think it is safe to say that Joey has started a new Information Revolution about conservation and protection of our beautiful planet and you and your fellow “caretakers” are to be commended for everything that you do. You let our baby Joey yell at you, Katmai to raid your pockets even though there is nothing in them for her and Tazlina to steal every toy and blanket from every other otter (I don’t think you could stop her though 😊🐾). You all are shining examples of what humankind should be. Thank you from the bottom of my heart ❤️
Awww this was so sweet! You are most welcome.
I enjoy your commentary on sea borne mammals very much. I would very much like to hear you speak of leopard seals. Sometimes demonized but still a part of our beautiful planet.
Beavers are rodents who are Glires in Euarchotaglire. Sea Otters in order carnivora, suborder caniformia which is in Euarchotaglires sister clade of Laurasiatheria.
"and so dang cute"
Apparently we're not gonna cover how ruthless and vicious these critters can be
Lovely video! Something you might be interested to hear is that the Beringia theory of how humans got to the Americas is quickly becoming outdated. There's more and more evidence showing that humans have inhabited these continents since before the Bering Strait would have existed, by thousands of years.
Interesting! I’ll check it out. Thanks for the info!
