SWIMMERS ON THE PLANET, BUT

NEW RESEARCH SUGGESTS EVEN

Sharks among the best swimmers

on the planet. But there's some

new research suggests, even

breath. While diving deeper

underwater. That crazy? I want

to hear this. Just start when

you hear why it makes complete

sense. Okay this new research

that they're doing, suggesting

that they hold their water.

Well, diving deep underwater is

for this reason they are. Here's

a new term for everybody. Acto

thermic ecto thermic. That means

they're cold blooded. Okay so

they can't really regulate their

going to regulate their body

temperature. Now if you think

about it, hammerhead sharks they

love the surface water 79 80

degrees, but when they dive down

to 3000 ft or so the water

temperature is about 20 that low

Do they go down like 3 4000 ft,

in some cases, and the and the

water temperature is 41 degrees

. Tuna marlin Mako sharks, They

have a way of regulating their

heat exchange through their

gills. Bluefin tuna can raise

degrees so they can adapt to

this hammerhead sharks can't So

the researchers are like, Wait a

minute. How are these sharks

being able to maintain their

freezing down there. Here's what

they do, and it absolutely makes

complete sense. They close their

gill slits on the side. You see

little gill slits there Because

what those gills or do it helps

them breathe, so the water goes

through the gills. Kind of goes

through their body regulates

their body temperature, But when

don't want that water going

through those gill slits because

it would cool their body to the

point where they could

potentially die, So they just

shut them and they hold their

could be down there as long as

17 minutes total four minutes on

the bottom to get their food and

then they come back up when they

reached the water temperature

that they like they open their

gills back up, and they start

circulating the water through it

again. Listen folks, it makes

complete sense, but it took us

hundreds of millions of years to

figure this out. How did we

figure this out? They went out.

They caught these sharks. They

attached electronic sensors,

Fitbits. Where we have Fitbits

on our shoes, Right? Put Fitbits

on the fins. And they were able

to regulate this as they went

down to thousands of feet. And

they were able to Figure this

out. And now they're saying, Hey

. There's gotta be other types

of fish and some sharks that

have to do the same thing to

help the regulate their body

temperature. It's amazing.

Listen they learned this

millions and millions of years

ago. We just learned this in May

of 2023 that they can do. This

is pretty fascinating. And I

mean, it's just one of those one

more thing where you go. Ain't

nature. Great I mean, just it's

just, you know, Think about some

of the alligators that have been

around for millions and millions

and millions of years reason

they have because they're able

to adapt and the fact that we're

able to figure out how they

adapt. Maybe that can help help

us adapt to other things, too.

You never know down the roots,

but that's how hammerheads and

three. I mean, At three or 4000

ft. They can survive by holding

their breath, so to speak. I

thought it was going to be a

pressure thing. I really did
