Why (only) some Sharks are Warm-Blooded
Вставка
- Опубліковано 28 вер 2024
- Sharks have the reputation of being cold-blooded killers that will attack and try to eat just about anything. But in reality, they are actually a lot pickier than many people realize - Attacks on humans are very very rare. But even the "cold-blooded" portion isn't even true - at least not when it comes to Great Whites. Because they are in fact part of a small group of sharks that can elevate their body temperatures above the water temperature - effectively becoming warm-blooded. Here's how they do it.

Thanks for watching.

Part 2 will be released in 1-2 months. For now, I wanna do other topics.
Also: This is one of the first videos where I didn't cover a story (so to speak) but more of a scientific concept, which required a more minimalistic animationstyle. I just hope it wasn't too dry.
Facts in Motion ok
Why the seal had a corckscrew shaped bite if that wasn't a sleeper shark?
I really liked when you show in detail why nature is awesome! Keep it up, it wasn't dry at all!
becuase he probably reused the same seal image from the sleeper shark video. Not that this is a bad thing of course, animations takes ages to produce.
I think Jose just wanted to sleepermeme. But yeah Moth, you're right.
1:35 Ahahhaha the roblox death sound caught me off guard
I honestly had to rewind it a few times because I couldn't except it.
Easter eggs are everywhere... even in this video _cant wait for justin Y easter egg coming, his existent... everwhere_
Me too lol 😂
same
Sean Barry same
You see guys, sharks aren't just cold blooded killers after all
They can be warm blooded killers too
You are savage
You are not savage
Are you savage?
They'll chump your head off while giving you the warmest hug!
1:35 O O F
TheGiftedFire Press F to pay respect
Bo Wen Zhou F
TheGiftedFire that death xcene is in roblox
TheGiftedFire do u play roblox
Its uuhhh, not oof. Get it right.
Press F to pay respects for the long-long Part 2.
where is it?!
Still waiting...
Still no part 2. Part 2 is the winds of winter of UA-cam videos.
2020 and the second part still hasn't been released. Kinda sad, it really was an interesting topic.
Exactly what i was looking for in the comments
O O F
Darcksage do u play roblox
chrty pdrns bruh, he has ains oal gown as his profile pictures. Do you really think he would destroy his "coolness levels" by playing roblox?
I can tell you/your team worked really hard on this video. It is very easy to watch and very interesting!
Ducks have a counter-current heat exchange system in their feet, which is how they can swim in near-freezing water with warm feet and avoid tissue damage.
1:35 if this isn't enough reason to call you one of the best UA-camrs, I don't know what is. Fantastic work as always!
Being Morgan Freeman is enough. A sound effect ehh.
1:35 😂😂😂😂 oof
that OWL 69 wow
Its uuhhh, not oof. Get it right.
Part 2 was then never released.
1:35 LMAO THE ROBLOX DEATH SOUND
hey dominoes ikr
Endotherm for the warm blood
Ectotherm for cold one...
Noted :)
Rodigo Duterte you are exactly right mr president
smart boi detected
@@donaldbaird7849 as were many dinosaurs. They don't aim for a specific body temperature like mammals, instead they just constantly produce heat to be generally warmer than their environment
everyone's so preoccupied with the OOF part, they completely missed the darn shark with fricking laser beams attached to its head
These must be so great to make! Diving in-depth into whatever topic tickles your fancy is the best way to study. Keep up the impressive work
Yup, it truly is.
1:33 omg lol Roblox death sound
ToxicMethods ikr
I fell like I’ve seen your comment on another video
I wasn't prepared for that.
@@maryhope5369 None of us were...
I truly enjoy these videos, hope part 2 comes out soon :)
As a biomedical engineer, these videos you make truly make me happy beyond words. When I finish watching them, my brain buzzes with inspiration. I'll try to support you as much as I can in the future. :)
thanks!
The seal just said oof like a roblox death
Great White: Changes from cold to warm bloodedness
Nature: Am I a joke to you?
i love the little touch at 1:35
Fascinating video! Amazing work explaining. You make marine biology sound interesting to the everyman, and I appreciate that effort a lot. Amazing work. I'm glad I subscribed!
Thanks for that lovely comment!
You deserved it, good sir!
1:15 Nice little Red October/Cold War reference you put in there.
Damn nobody's actually talking about sharks in the comments lol.
One of the best shark-related videos I have ever seen! 👍🏽👍🏽💙🦈
Fabi G Without a doubt. I knew they could "cook" their meals but not the rest of this. Very interesting. Most shark videos are about teeth and eating.
The salmon shark are by far the most facinating to me with their ability to be warm and hyper active hunters even if cold waters.
This channel will get a million subscribers in no time i can feel it.
1:35 THE F*!@ING OOF
I haven't watched this channel in a long time, but wow there has been big change the production quality. Congrats
it should be noted that their are some noteworthy advantages to ectothermy as well. The primary one is that, due to not spending energy to maintain body temperature, they can afford to burn fewer calories as their resting rate than a similarly sized mammal.
I love your chanel! Your voice is awesome af too!
I appreciate the work and knowledge that you put into these videos and how well their animation style looks. As a biology major I find these videos to be fun an interesting little topics that you explore and present so eloquently. Please keep up the good work.
1:35 WHY
Beautiful art and Editing. Great video.
1:36 That Oof though.
I wish we had this is grade school
I like the "borrowed" TierZoo stat graphs
Omg the "OOF" at 1:34 😂😂
I wish UA-cam would develop some algorithm that would either put all repetitive comments in one or just have a set number or % of the comment allowed to be of the thing being said over and over.
Then one wouldn't have to scroll through the %85 if the redundant ones in this video. It makes it difficult to find the comments actually related to the subject of the video. Which is really cool and intriguinging. Worth commenting on and discussion. While Roblox can be talked about on Roblox videos. Yes, every Roblox player noticed the noise. Now, how bout them sharks? Them hot heated sharks.
Your animations are so cool! Love your videos
My cat LOVES your vids animation. Lol. He tried to attack the TV when he saw the seal.
How exactly does the counter current flow help the desert fox in reabsorption of water?
Works very similar to how heat retention was shown in the video.
here are a few points you can google if you want to find out more:
"nephrons countercurrent"
"Countercurrent multiplication"
"juxtamedullary nephrons"
It is really cool to see the that the countercurrent principle seems to be a evolutionary solution to so many challenges these species have. I know that humans have a countercurrent multiplier in the kidneys, to help with filtration. Wonder if there is a more efficient system than this one...
1:35 OOF!
😂my guy did you just use an “Oof “
HA, I recognized that spiral wounded torn apart seal from one of your other episodes :) Excellent work on these, btw!
awesome video but where is the next part???!!!
Still waiting for a part two on this and more content in general!
1:35,the roblox death sound,what a genius.
So this mechanism is something of a bioreactor?
1:33 did that Seal just _"Oof"?_
Amazing video as always !
It's 2 years later, but I can't find part 2.
Love the Roblox death sound, also, really cool topic.
this is complicated, I almost can't understand, until I read article about muscle cell.
Sharks with frickin' lasers attached to their frickin' heads
What happened to Part 2?
Bruh that seal went oof
Where is part 2?
Anyone notice the corkscrew wound on the seal on the intro? maybe FIM will solve the corkscrew seal killer!!!
why does he sound like Dr. Killinger from Venture Bros ?
"dis is my magic mystery murder bag you silly billy"
8 months and still no part 2?
Don't see it in comments so just FYI, the collective noun for sheep is sheep not sheeps. In English there's always an exception.
The list of fish with elevated body temperature is incomplete. The manta rays and devil rays have "heated brains", while opahs are the only truly endothermic fish.
Du hast so einen Akzent
Did... did I just... hear an _oof_ ?
Nah 😂😂😂 he didn’t just use the roblox death sound
I love their sense of humor
That roblox oof tho
2:52 freaking sharks with lasers!
Great video! Thanks for sharing.
Very informational!
If you take the thumbnail and crop it to just the shark’s head, it’ll look like it’s stepping on a lego.
I'm still waiting for pt 2.
The Opah is also a warm-blooded fish.
I love this channel !
Nice oof meme
Still waiting for part 2...
Still waiting for that part 2 my friend....
Any day now... I can feel it...
Awesome animations, einfach schön, ehrlich!
I cannot believe he used the roblox death sound when that seal got got
So if great white's muscles are in the body's inner parts, where are the other organs?
I love this channel!
I love your intro!
1:35 Roblox sounds roll in as a seal gets murdered lol
Note there are some other mesothermic animals (mesotherms being the term for animals that fall in between endotherms and ectotherms) Leatherback Sea Turtles are Mesotherms for instance as well and while it is far harder to tell for extinct species archosaurs show signs of a mesothermic to endothermic past though that is still an active area of study.
Additionally it isn't a one way street to endothermy as there are evolutionary pressures that have lead to the loss of temperature regulation. Modern crocodilians show many vestigial signs of having arisen from ancestors with regulated internal temperatures such as a vestigial 4th heart chamber. And several groups of modern mammals have lost endothermy such as naked mole rats and 3 toed sloths.
Sooo... Where's the second video?
I see what you did there with the OOF sound.
wow it's been 6 months and I'm still shocked you really pulled an oof on us
Where's Part II?!
I thouroughly enjoyed this video.
SO where is the next part???!!!!!
I love your videos do more like this homes
"Oof." -Seal, 2018
1:35 why I hate lifeeeeeee
Kids these days....
6:30 Another animal which has this countercurrent blood flow system are penguins in their feet.
I love this guys voice XD
Great video
what happened to part two though
