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
