"THE IDEAL MALE BODY"
Oh man my confidence boosting fr
Lmaooo
Ideal male body duh
man I wish I had top comment
Iseal male body
YOU BEAT ME TO THE JOKE AGHHHHG
I love how Neil the Seal has such a reputation for being the neighborhood bad boy, but the locals just have to accept him to some degree. I hope the future brings a happy outcome for him as well as the locals.
Doubt it.
The moment he gets a human hurt, some reason/justification for shooting him will be found.
At least thats usually how it goes with bears or tigers or elephants when they show up in settled areas and loose their shyness.
Its cute how the folks in the village work around him, but doubtful if its sustainable. Especially if he moves into sexualized agression with viability.
@@user-un8tv1pp8mit's very unlikely the Tasmanian Parks officials will resort to shooting him... Australia is one of the better resourced countries at dealing with this type of thing.
Although there's a lot of discussion about how they're going to discourage him from coming ashore in the future. They don't want to interfere with him too much, but obviously it's not desirable that he continues to interact with people for his wellbeing and people's safety. But he's certainly getting the attention from the folks who know what to do about it.
Beach Master sounds like one of the dad archetypes like the Grill Master. An Eldritch creature in flip flops, cargo shorts, and a bucket hat reminding everyone to wear enough sunscreen.
I know this guy lol
And a metal detector to find absolutely nothing with
@@exiledtobronze8694 no that is not the beach master. those are the foragers together with the beach fishers. the beach master is the one that controls the lifeguards (they may one day become the master) has the absolute best spot on said beach with enough food and drinks to last.
and when they smell competition they will come barring there rolled up newspaper and a breath that smells of a lot of coffee and heavy tobacco.
@@realscienceRemember to reapply, Steph! You don't want a sunburn like last time.
"It's not my fault if you get sunburned!"
Resident: "sigh....Neil, you really can't keep doing this..."
Neil: (side eye) "...AAAAAAAAA"
I'm an Aussie and I've always felt for Neil the Seal. He's going back home to fight and mate...but he's alone there.
might be something aquariums could help with
Yeah, if he's ever going to become a Beach Master, he's going to need to find a new beach!
Why they kinda looking like my brother
😂
hello kris
Who is this?!
And like my teacher who was called as "penguin" by everyone. But he was as wide as these speciments😅🤣
Atleast he's cute
5:34 “only 30 to 40 percent of seal pups survive their first dive” that makes me understand why a long-surviving elephant seal is so aggressive, the chill ones probably died on day one!
How does aggressivenes help with avoiding sharks and orcas?
@@whyarewestillhere7073may something to do with fight or flight. When animal have high fight or flight respond tend to be more aggressive
I don't get it. With a two in three chance of death in "their first dive" what is the chance of death in their second dive.
I mean these seals dive many times a day. What would the juvenile population be after a week or so?
Out of a population of 1,000 pups there would be less than 4 alive after just 5 dives each - (1/3)^5~0.0041 - so I guess they're SUPER fast learners ... or something???
@@primus4cameron my guess is they have fast developing instincts, but there’s probably a slight window during the first time when they’re very distracted by the cold and incapable of seeing far enough to understand what to do.
@@whyarewestillhere7073 avoidance is not the only strategy required to survive against the vast biodiversity in the wild.
If a shark bites a human, for example, get away if possible but then you punch its nose or eyes if you can’t.
Most interactions are like this: avoid but fight if needed. And it often is needed.
5:15 omg that seal cried in the perfect moment
Real science exposed telling seal pups they'll likely die
@@davidegaruti2582 Real Science keeping it real am i right
It's hard for a smol seal out here. That's why puberty is their comeuppance.
6:36 I didn't they could scratch their own head 😂😂😂😂
That through me off too. Looked straight up like a human 😂
Me neither! I was very surprised by that
Fr 💀
Yeah, Erm what the sigma?
so can cats and dogs whats the surprise?
"7 tons of raw sexual aggression" reminds me of highschool
😂
My sister walked during the "raw sexual aggression" part and said, dang! What are you watching!?
Bruh💀💀💀
Not that bad. Just rewind and show her
show her
@@martinketchumthanks for reminding me how dirty my mind is
@@noend7879bro get off the internet lmao wtf
16:30 "it becomes greatly elongated during the breeding season, and can then be erected"
lmao, looks like Charles Darwin had fun writing his notes xD
AYOOOO
Silly, silly Charlie
@@FutureAIDev2015why does that translate to come on..?
Considering their deep diving and huge appetites, I'm surprised they're not covered with scars from Giant Squid like Sperm Whales often are.
I think shedding their top layer of skin each year would remove any superficial scars.
Despite their size, a Giant Squid would probably be able to overpower an Elephant Seal most of the time, or at least long enough to drown them. Not saying it's impossible, but it is highly unlikely that an Elephant Seal would survive the encounter which is why we haven't seen any with squid scars.
@@TheRotConsumes. Remember that Giant Squid come in ALL SIZES. They don't start out huge. They start out tiny, and grow bigger over time. This means that an adult male Elephant Seal could successfully attack the vast majority of Giant Squid - all but the very biggest of them. Although if he attacked one that was about his own size, I'm thinking it would put up a pretty good fight before eventually getting metabolized into seal blubber.
4:57 - Okay, that is a fantastic facial expression. I'm low-key disappointed this wasn't used as the thumbnail.
It's hard not to love Neil the Seal.
On the South Georgia, in some places there are still some buildings left. With walls and roof.
Even if the big male elephant seals want to fight each other most of the time.
When it is the breeding or moulting time of year, if you look inside those buildings, all you'll find are HUGE male elephant seals.
They clearly like being out of the wind, and perhaps the sun. And no females, pups, or small males are in there. The big males appear to have scared off everyone else, but they're willing to share the space with each other.
It's really surreal looking. Like some nightmare frat.
If you are in the States, you can see Northern Elephant seals at several locations along the West Coast. The biggest and easiest to see are at Piedras Blancas just north of San Simeon. CA. Also at Ano Nuevo State Reserve just north of Santa Cruz and Point Reyes north of San Francisco. Worth the visit particularly around the new year when the pups are born and the males are fighting over the females. Huge, very impressive animals.
Would love to see them one day
@@realscience I've seen 'em at Ano Nuevo (an official tour), tried to do it at Piedras Blancas (they were RIGHT OFF the side of HWY1, but my wife would freak out when I tried to walk down among 'em==at the time I went pre 2000 it was totally uncontrolled); and "somewhere south of Halfmoon Bay", my brother in law's Akita and I walked up to an exiled 'bachelor male' just chilling against a sand dune. The Akita tried to make friends but the Big Guy wasn't having it; he finally rose up and 'roared' at her and she got the message and left with me. I got close enough to see the 'half moon' shark bite scars on it's flank and the code letters marked on it's pelt with hair dye.
jejeje ano nuevo
@@acidbog yes,right in Santa Cruz County
@@nickmitsialis it's just funny because when Ñ is replaced by an N it says new butthole and that will never not be funny
Amazing writing, as always.
Really impressed by your story telling, very well structured and engaging, very interesting facts.
Stumbled upon the channel when the video about crows was recommend.
THE IDEAL MALE BODY........hmmmm, gonna send this to my trainer and tell him these are my body goals
well start to eat a lot of fish in that case. it helped them well.
Real Science is one of the best storytelling and well researched factual content creators. One of my favorite RUclips channels is Real Science. Real Science is one of the greatest RUclips channels of ALL TIME!!!
11:34 can someone tell me how scientists figure this out? Like I imagine its pretty hard to analyse an elephant seals lungs whilst it’s diving
So size disparity between male and female individuals in a species correlates with the level of sexual aggression. Pretty good rule of thumb I guess.
often for land based vertebrates it is important for the male to show why it is the best candidate for a female. by being bigger and stronger then all others it showed that it had the most resources available to survive and so it's offspring will have the best chance.
in other animals you see the opposite males are much smaller as there only function is that mating and after that or beyond that they are worth less.
they can be tiny as the female will have to do all the work it self.
very true, even true when the females are bigger, like in hyenas. Or when they are much much bigger, you have the insects where the female eats the male. Thankfully I dont know any vertabrates that to this.
I would say it correlates with species with high levels of polyamory. If only the biggest and strongest get to mate, there's a huge pressure to be big and strong.
@@evilbred974 yeah I should say ‘sexual aggression in males’
@@evilbred974 I don't know if it's true, but certainly makes a lot of sense. I know that with Golden Eagles, who mate for life the females are larger than the males.
Have a faint memory of a nature document, where an adult elephant seal bull was sexually frustrated and crushed a spine of a pup. Those people are way too relaxed and content around a beast like that.
I never thought about marine mammals and decompression sickness. Theyre so amazing
Fight for the "beach", the "beachmaster". Juvenile of me but I snickered.
Bender is the ultimate beachmaster
I've never seen a seal scratching its head before. That was the wildest part of this whole video for me.
Same heere 😂 it was a truly Wau moment
Do they have Neil insurance in that area? Surely yes right?
common home insurances cover wild animals for structural damages
I feel like it would be expensive
I think they might consider than an act of cod 😅
"what are you gonna do big guy? sit on me"
Neil "that's not only the plan but my motivation as well."
Will it be a problem for Neil the Seal when it's time for him to start a family and the "home beach" he returns to every year has no females, or any other seals at all? I'm afraid he's going to be stuck living around humans, maladjusted and unable to get on with his life.
He long ago reached sexual maturity, and yes.
He'll end up finding himself a single New Zealand mother and working a dead end job until alcoholism and heart disease ends it all.
Thank God im not an elephant seal , would definitely have died a virgin
My spouse has memorized how to make coffee at home for me. We live rural too and order coffee beans because I’m picky. We got a grinder and a nice pot for our registry and as someone who works from home- this has made my job and my life so special. I love coffee, sometimes he surprises me with having it made before I’m up, then I sit down at my desk or studio space and get to mello to life in the morning lol
Every video is a gift
I KNEW this video would involve Neil!
Perfectly timed upload for me to watch before bed after work. Quickly becoming a favorite channel of mine!! ❤❤❤
NEIL MENTIONED?! LETS GOOOO!
NEIL 🦭NEIL🦭NEIL🦭
They dive down to Sperm Whale depths? I had no idea. That's crazy!
The Elephant Seal breathing out before a dive would also make it less buoyant
12:22 Pinguin casually walking by 😂
Elephant seals got nothin on M’Lord
idea:the insane biology of the mudskipper
Whoever wrote this needs to look up what decimation and regularly mean.
Favorite thumbnail of all time😂
All I could think about was the Futurama episode about them. It was pretty much spot on!
how did I not know about this
@@realscience Futurama Season 7 Episode 13 Naturama
The transition from seals to coffee is on point.
I think Antarctic Ocean sounds cooler than Southern Ocean, especially because there's an Artic Ocean in the north
Well done. Thoroughly informative. I learnned a lot about these animals I thought I already knew all about. 😊 Excellent narration. Appreciate the very subtle background music as well.
I always watch as soon as you guys post. Love your content!
16kg of food per day?
Hey, looks like I'm half-way to being a beachmaster already 😆
Awesome! This video is so adorable; the seals look so cute and funny. It's delightful to see them playing and interacting with each other. Thanks for sharing!
Man I've been waiting for this one! I was kinda hoping you'd go into how they actually move on land. It's crazy how fast they can move forward or backwards without legs and the flippers don't seem to be able to do much at all on land
Another masterpiece as expected!
this Ken’s job is beach ✨🏖️
😂 shocked there weren't more Ken / beach references!
science is craaaazzzzyyyyy
Love all the "insane biology of:" videos. Great work!
New to this channel. This was surprisingly well done. Good job!
Something to strive for. Time to reverse the weight loss after a vacation full of delicious food.
12:20 for some reason that penguin casually strolling past the camera is hilarious to me
Another fascinating video! Thanks!
This is what peak performance look like
Hummingbird next please!!
Quick question, if 1% of males father 80-90% of pups, how do elephant seals prevent inbreeding?
They don't. As it turns out large portions of the animal kingdom don't really care about inbreeding, usually sheer volume provides enough genetic diversity amongst large colonies / populations, and the issues really only compound when populations dwindle
Lots of moms.
@@Mike.The.Jewelerthanks, that’s really interesting
@@gracielags6826 happy to help friend!
In addition to what mike said, if some of the young have negative mutations, they generally die before adulthood so that the mutations don't spread. Inbreeding is more dangerous for humans because so many of us survive to adulthood.
Awesome presentation; very informative and not boring; it kept me very interested
holy crap...I've only ever seen cute elephant seal videos, these guys are SCARY! also - wow :D
Yeah if that’s the idea male form, my high school history teacher would definitely be a beach master. Was more of a desk stool master back then though.
6:38 my guy thinking real hard
I never would have thought any mammal would EXHALE all of their air before diving, surviving for 2 hours with NO AIR! So cool!
Not only do elephant seals have noses reminiscent of actual elephants, they can be almost as big as elephants, too!
I really like your material & research.
I love how the dominant males are called "Beachmasters"! Coolest name ever!! Way cooler than "silverback" ! 😅
Dunno about coffee, but CHOCOLATE is a whole food group in this house.
Learning something new after months of distancing away from gadgets due to exam . Great video 😁.
Wow that study is crazy. They spend most of their time underwater when they’re not on land. It’s awesome to think that these behemoths are likely diving at any given moment. Just hanging out at 2500m chasing squid and fish around.
Definitely clicked on this specifically because I keep watching neil videos and was pleased to see him come up lol
I was doing some research on this for a book I'm writing, and I read that the male nose is so large that it can recapture water during exhalation because they spend so much time on the beach that they won't eat or drink for months while they compete for mates.
currently working on elephant seal prey caloric density research, this is the perfect video to have as background noise! XD
I love ur videos sm
Elephant Seal is the epitome of being built different
I'm torn between Neil McBeal the navy seal and "loose seal!" jokes
I would be delighted to have Neil the Elephant Seal hang out in my back garden. These people just don't appreciate him for all he's worth. Tell him to come to Winnipeg and I'll happily host him in my garden (though getting here, as it's land-locked, could be a bit of a struggle for him).
In my dating experience, chocolate is more universally appreciated than coffee. Getcher caffeine with theobromine and sugars, too!
It was an ad, not science
Simple...I see a new video from Real Science, I like, I download to my youtube account, and i download a version to an external SSD. My personal favorite is the video on the Harpy Eagle. Thank you for the high quality content as always!
Oh my god, I was not expecting to see Neill, the loveable menance of seal
This video is where I learned that the nose shaped pokemon “Probopass” and “Nosepass” come from the scientific word “proboscis.”
Another unreal standard. How to get more blood?🤔
I hear they keep lots of it in banks.
I love how seals use their flippers to scratch their backs
"battle cry" - sounds like flushing the toilet
Could you make a video about the insane biology of bi-valves? Those things are crazy and so alien.
finaly something that i can relate to.
Decompression sickness is only a problem on bottled air. If all the gas in your lungs was inhaled at the surface then you won't be inhaling denser gasses as you dive - which is what causes the build up of nitrogen.
Neil the seal, such a fire name.
😂😂😂😂😂
omg those emojis are so cute😆🩷
That tumbnail is everything
I would be a land master if I could stop spending all time all my time watching all these videos.
23:53 why did you wait so long to tell us this, ive been eating like an elephant seal in hopes of becoming a beachmaster with a harem of my own
Cant really compare human diving to Elephant seal diving. We get exhausted fast.
interesting story! thank you
I love seeing anything about Neil
Thankyou for not body shaming Neil’s dad
Great video ❤
Yup, that's beautiful!
Ok guys we need to evolve to Elephant Seal. Once a year we will get all the men from specific areas together for one massive fight club to determine our dominance in the gene pool.
Cool ass video. I love me some elephant seals.
