Dang, corpse whale is a pretty metal name
Nár (pronounced like "nowr") is the Corpse. The Hval (pronounced like "kval") is Danish (also other Scandinavian languages), while the Dutch gave us the "w" part, changing the Hval to whal.
Gojira × Behemoth
“Narwhals, narwhals swimming in the ocean causing a commotion”
"'cause they are so awesome!"
This has been stuck in my head for like 2 months 😵💫
@@windhelmguard5295 Narwhals, narwhals, pretty big and pretty white, they'd beat a polar bear in a fight (except not really, according to this video)
AHH weebl's legacy still lives on after all this time, excellent!
Under water unicorn 😂
Ah... now I know why narwhal's are so shy... not very good at breaking the ice.
Narwhals: Have long tusks on their heads.
Scientists: *Why are you like this? WHY???*
These videos are so informative, genuinely great quality content.
Yes, with the exception of Dune worms.
This one was particularly interesting to me. Great content. Narwhals are indeed more extreme than I had known. Far more.
@@infinitemonkey917 Yeah I skipped that one bro
Narwhals look so magical to me. I heard this from another show that they are also very nervous around people so that's why we cannot learn much about them this and their environment makes it more difficult to study them enough.
You’d be nervous around a species that hunts you too.
Their closest relative, the Beluga whale, is social though.
@@LeonardTavastit's a defensive mechanic. I become talkative when I'm nervous also lol
They're magical because whenever they're mentioned, somebody mentions Donald Trump.
that narwhal sitting there just saying fuck was hilarious
The real name is
"Toothpick nosed pickle dolphin".
It's not a pickle!
0:46
That fart sound effect is PRICELESS 😅
I wasn't ready😭
It was me; that was my fart
Followed by "Maybe you're thinking, that's still a majestic creature..."
🤣
Unexpected moment 😂😂😂
This is the absolute best video I've seen on Narwhals. I've watched so many over 40yrs. I learned more from this than any. You make absolutely fantastic videos. Science teachers in elementary & middle schools could add them to their lesson plans to make a huge difference in students grades.
I’ve genuinely learned more info on narwhals in this one video than in my entire life and narwhals are one of my favorite animals.
This just exposes you as extremely lazy
An informative and entertaining video on Narwhals. Thank you Stephanie. I look forward to your next one.
Every time I see narwhals, I wonder if they really exist. Even though I heard about them from many documentaries, they still feel out of this world. They’re amazing creatures.
Very comfortable speaker and seems comfortable talking. Most people look uncomfortable or forced when do documentary type videos. Keep up the good work.
This is my first impression of her first time I watched their documentary years ago. Sounds very passionate on the topic as well
National Geographic or Discovery need to contact you to narrate all of their programs!! You're voice is so soothing!! Great video as always!!
Obviously, the tusk is for cleaning the gunk out of each other's mouths and/or chipping away at ice. A toothpick, if you will.
I'm glad your continuing to make these amazing videos. The quality is great and so informative. Keep up the great work! :)
you're*
@@DirtyBobBojangles Shut up please
I love narwhals, pretty big and pretty white. They're like an underwater unicorn that got a kick-ass facial horn. They do cause a commotion swimming in the sea, but that's just because they're so awesome.
It still blows my mind that they're the inventor of Shish Kebab.
One could make the argument that they're akin to the Jedi from Star Wars, except that they're in the sea.
I'm pretty sure that, should they fight a polar bear, they'd emerge victorious!
Tjis entire chain is such a great reference.
You forgot one of the main uses of the different claws on crustaceans. Most have one crusher claw that has far more muscle in it that is used to break shells and whatnot. The other is primarily a holding claw.
nah
Great videos always. Thanks and keep them coming.
Das diese wunderschönen Geschöpfe noch nicht ausgerottet wurden, wegen ihrem Zahn, grenzt an ein Wunder!
Stimmt
Amazing video! Actually informative and well-researched
thank you so much!! marine mammals are my absolute favs and this video is so well made and informative!! ahh i almost cried because i love your vids sm!
late on watching this episode...would like to see you cover the pitbull fishing bat...like echo location is complex enough but fishing with echo location is an absolute fascination
great vid as allways
Two points I have to make
1. I love that the videos are not only interesting but they keep getting funnier
2. thanks for letting us put a face to the voice
so ... just keep doing what you are doing
This video was awesome! If I may provide a suggestion, I think making a biology video on the African Lungfish would be so cool! Theyre so interesting with how they can bury themselves in the ground for months basically becoming a husk when there is no water and then come back as if nothing happened when the water returns.
Do yourself a favor and watch this video at 1.5x speed. You’re welcome
Thanks for the reminder
I always watch videos as 2x speed lol
"It stops Cthulhu eating ye!"
Great video thank you! Narwhals are fascinating!
WoW. So easily digested information. Thanks and great job.
Nice to see who's been blowing my mind for all this time. Great video once again.
Is this the first time face reveal? Took me by surprise
These videos are absolutely amazing and really interesting
The rhythm of the video, te quality of edition and the depth developed about the topic are really outstanding. 👏🏽
Real Engineering: "We're going to appear on camera more often to combat the usage of AI"
Also Real Engineering: uses AI anyway
what a slap in the face
So incredibly grateful for your channel, diligence, and hard work. We all benefit from it, which is the noblest of pursuits. Thank you. 💕🥂
I loved this episode. Thank you. ❤
As always , great content ❤
When you mentioned that narwhals are at risk of Entrapment, I thought you were about to say that their most feared predator is Catherine Zeta Jones.
I find it weird that tusks mostly form from one tooth, that lack of symmetry...
Maybe it's also like a sensory organ for hunting?
When something moves, that movement ripples out and moves water along the tooth at a different rate than if there had been no movement. That different flow rate might register to them as a change in salinity, similar to how the movement of air from like a fan or something can register as a difference in air temperature to our own skin.
The tooth could be an alternative to echolocation for hunting scarce bottomdwelling prey and cephalopods in very deep, dark water. One that's also much more energy efficient, because the animal doesn't have to produce very loud sounds.
I don't think it would otherwise make sense for additional salinity to the tooth to trigger an elevated heart rate, as that would just mean that the narwhal consumes even more oxygen right when it is about to become much harder for it to breathe. It would also lead the animal to *avoid* breathing holes in the ice, because that's where ice growth is going to be the most intense (cold air meeting liquid water) and thus salinity will be too.
I just wanna say I really love the work you guys do with your videos and the amount of effort you put in to making them look and sound as premium as they do for a CZcams video. I also love how scientifically informative they are when explained, however this video is probably the first I’ve seen that looks like click bait for people who don’t really care about science. It makes the video feel cheap tbh and less appealing. I watch your videos to get away from crappy content. Please don’t change for good!
Ever since I found your channel I have loved your content! Keep it up!
Well done. These are one of my favorite marine mammals.
Very informative video, thanks for sharing. This video is now making me learn more about this amazing fish
All whales are actually mammals, not fish.
obviously a Moby Dick fan heheh.
I was first made aware of the Narwhal spike/horn when someone used it to defend themselves during an attack on a bridge in London.
I have buck teeth... Next time s.one makes fun of me, I'll proudly declare myself as the dream boyfriend for a unicorn
I've been waiting for this
I can never unlearn the fact that a bunch of science hippies made narwhal tusk condoms to test the “salinity sensor” hypothesis.
It shoots laser lights that we feline enthusiastically chase
TBH, your comparing crabs and mammals, thats a good way to anger evolutionists LOL
TBH I used to believe evolution created our world but looking at the whale evolution story just couldn't cut it. So a 4 legged land dwelling mammal had its nose mutated to the top of its head and then somehow its back legs turned into flippers. Lightbulb! It was designed to flourish in its ecosystem. There is soooo much evidence for design AND you don't need blind faith to accept the big bang story. Once you realise you're not an 'accident' and your heavenly Father loves you, life is purposeful exciting and real. Jesus loves you bro! Messiah 2030
How
She has upped her game >Jokes n facetime. Dont know her name but comfortable to listen to and her enunciationis incredible. sometimes i wonder how many takes..
Her name is Stephanie :) Says so in the description
@@MotoHikes Cool, nice to know. Thank you. :)
Don't need the facetime
@@eSKAone- I feel the same with fart jokes.
I Haven't even realized what it was until seeing it at the comment sectiontbh.
Until then I have thought it is an unintended error. Squeaky chair or something. I'll never understood American fascination with inferior, undemanding under-belt jokes. This is what makes most Hollywood 'comedies' unwatchable.
Consumers are stupid and least common denominator is everything is the movie industries mantra.
Although their fascination with sexual, genital and excreaton and fart related is understandable, seeing the us is a military superpower accelerating towards it's end. Same thing happened in the imperial Roman empire (and it is also the reason of their SJW and gender and race hysteria imo).
Good for China and Russia, I guess.
It is possible that the tusk itself could be used as a pressure transducer akin to the ampulllae of Lorenzini or lateral line of a fish to sense movement within the water column for depth, salinity as well as electric field of prey. As a dentist, one appreciates the piezo electric effect of dentin and cementum. The tusk could easily be akin to a piezoelectric beam type transducer that could register how much force a opponent could apply like in a jousting contest, and stave off injury by noting the amount of force that is being applied to the tusk. The human tooth is capable of sensing in six axis micro movement of 5 micron. The bone to tooth interface of the periodontal ligamant would be the gross input and the length of the tusk is a force amplifier with exquisite fine descrimintation. EXCELLENT Video....... Cheers.
I like your CZcams Channel. You have made me interested in biology.
I absolutely love
🌌Cell To Singularity🌌
and I was actually playing it while watching this video. I've been a player for a few years now and this tapping game has helped me so much with my idle picking issues because it gives me something for my hands to do while I'm watching something or thinking, and I've learned so much from it's "story" and events.
I genuinely can not recommend this game enough ❤
7:08 is that an AI image?? It looks freaking weird.
Definitely is, noticed something was off about it and then saw others in the comments noticed too
@@marcdiaz8639 I don't understand why they wouldn't use a real image or get an actual artist to render something. Really disappointing to see the use of AI so normalized, especially by a science education channel I respect so much.
@@KrazyKaiser I’m hoping it was just a mistake, I think they’ve accidentally used AI images in a previous video and addressed it. But it is a shame, especially since I myself am an artist. It’s lazy and honestly unprofessional especially for an educational channel
@@marcdiaz8639”i’M aN aRtIsT mYsElF” shut up about it already. No one cares. Quit begging to be seen as a victim, loser.
Nice to see the face behind these fascinating videos. I really enjoy the content you create.
Those tusks are also sensitive to pressure changes.
This means they may also be capable of sensing and tracking sources of sound/vibration in even the darkest waters. Like those of prey.
I really like your channel. Please keep it about the science, i know you will eventually get sponsors, but please always keep it about the science. Thank you for the knowledge.
Small thing, but dentinal tubules are only on the root surfaces of teeth in humans. Roots do not have any enamel on them. They do have a thin layer of cementum but usually that layer is worn away, leaving the tubules exposed. That's why people with gum recession get sensitive teeth
It's like the awl on the back of a Swiss Army knife - you find uses for it.
Corpse Whales with giant toothy horns ARE Majestic AF. Mother Nature's design is not bound to your standards.
Ever since I saw them for the first time in national geographic, they're like my favorite sea creature. It's the mystical appearance that they give off and the stark difference that it has from other sea mammals.
I love to learn from a really smoking hot science Communicator. Keep up the great work. You rock
I LOVE when she does creatures I've never heard of! Cool video.
Wow...lol
First time watching your channel. Saw your sponsor for Cell to Singularity. I’ve been playing for a while. I love this game, and they continue adding things to it.
5:28 That's why everyone calls them the Masao Kakiharas of Arctic waters. It cannot be just me.
That guessing ridiculous reasons was great, you could repeat it with future videos of yours (when applicable). Great video!
fantastic, surprising, enticing - as per usual on this channel
We need a dedicated video on Chickens
Yeah, that would be good. Also, the many different ways of cooking them, too!
Realest thing ever
It was as always interesting.
Ive become kind of addicted to this game over the past few months. You could play it all day long, and for many months. Its dangerous :)
I learned something, and that means you're doing a great job!
My guess with their tusk was that it was used like how a swordfish uses them. And that they were for show like attracting mates. This video was pretty interesting. I had no idea they could sense anything through them, and using them to find open areas to breathe makes sense too.
As a computer science major, I never thought I'd fall in love with biology, yet here I am, binge-watching all of your videos.
It looks as if it would be right at home at a ren fair jousting event
I say its used to check if the cake is done or still need some time in the oven
Do we know about the early ancestors of narwhals? did they also have weird organs, like the past relatives of present day sharks and elephants?
Good point. I used to believe evolution created our world but looking at the whale evolution story just couldn't cut it. So a 4 legged land dwelling mammal had its nose mutated to the top of its head and then somehow its back legs turned into flippers. Lightbulb! It was designed to flourish in its ecosystem.

Could you do a video on the Amur Tiger?
That was so cool. Thank you.
Thank you for fascinating information. Not only information it is tool to manipulate properly nature
Narwhals, narwhals! Swimming in the ocean! Causing a commotion!
Narwhale: “Wouldn’t you like to know.”
not sure how much i like this style of video. i prefer just the learning, and i usually do from all your videos. i didn’t really like the ‘kiddie’ jokes and unserious comments you showed.
0:40 LOL the sound got me
Regarding your last point, I wonder if anyone has tried replicating that saltwater sensititvity experiment with the females - specifically trying to see if their internal teeth have a similar structure and sensitivity to salinity. If they did, then that might be a point in favour of the idea that narwhal tusks are just mutated versions of a preexisting trait.
It’s great to put a face to the voice that helps me sleep.
It was interesting to see you after long time hearing voice only. My be another idea for a video: how humans brain "build" face from sound
"Non fiction game" hysterical laughter.
The narwhal bacons at midnight
Narwhals. Narwhals swimming in the ocean causing commotion swimming away cause they are so awesome. This song was like my toddler anthem 🙂
Am I the only one screaming for protection when we consider the tooth..... like a rhino
In my humble opinion, a Narwhal *is* a unicorn. A sea unicorn to be exact.
Narwhals are so majestic and beautiful. They are truly unicorns
This presenter is gifted, and always a good narrator.
Wow I was just watching the Everest video then this one comes out! Perfect timing, love the channel and the production quality is so good 😍
Wow, very cool! I have long been puzzled about narwhals. I will check iut the game too.
2:56 Nobody said break through the ice? ...really?
A Narwhal tusk is a multifunctional adaptation. Sensory organs and appendages are not necessarily only for one sole purpose and rarely are or only started out that way and then found to be useful in other ways to survive better.
Narwhal tusk makes a fine acoustic guitar nut and bridge.
At some point even the most ardent marine biologist has to shrug and say "does it really matter what the giant tooth is for?"
tripe
@Dr.Ian-Plect exactly, at the end of the day, who cares what the tooth is for, even if the narwhal uses it to poke out eyes lol
Magnificent video!
Being an apparent over sensitive tooth, I wonder if researchers have tested for electrical sensitivity? Having a “walking cane for the blind “ when in deep darkness on limited air that could pick up the subtle electric pulses of fish and squid would definitely be useful.
