fact
despite sharks looking like the literal
embodiment of a sea monster in the
presence of billions of them out there
in oceans across the world only around
80 unprovoked shark attacks on humans
are reported worldwide each year in 2016
only four people in the world died from
shark attacks while at the same time at
the humble vending machine injured 1730
people and killed four of them in the
United States alone statistically a
vending machine is much more
life-threatening to you than a shark is
but sharks didn't always used to be this
underpowered the great white is probably
the most menacing shark that's still
around out there they can grow up to a
frightening 6.1 meters long and weigh up
to 1,900 kilograms
much longer and heavier than a Toyota
Corolla while their teeth in their jaws
can grow to just under 8 centimeters
long which helps to give the great white
the most powerful bite in the animal
kingdom capable of applying a force of
18,000 216 Newtons while the most
powerful human bite measure is only 1317
newtons great whites rarely attack
humans but when they do it pans out a
bit like this imagine that you're
helpless in the water and you see a
great whites they'll generally circle
around you before bumping into you and
fighting to see what you are thrashing
or panicking is the worst thing that you
could do in the scenario because that
could lead the shark into mistaking you
for prey and they'll continue attacking
and eating you as fearsome as the great
white is however it's basically an
extremely nerfed version of its close
relative that existed over two million
years ago in the same oceans the
Megalodon Megalodon probably looked very
similar to the great white only it was a
lot spookier because it grew to be more
like 18 metres long and could weigh up
to 59 tons here is an average American
male placed side-by-side so that you can
see how quickly you would die if you
ever met one for reference I'll also put
down a Toyota Corolla an African
elephant a tea
Rhett's a school bus a sperm whale and a
four-story building all of which are
smaller than a Megalodon at 54 tons in
weight not even an m1 Abrams main battle
tank is as heavy as this Godzilla shark
but that's not the only reason why
Megalodon was so terrifying
the blue whale for example is a lot
bigger and it's still around today but
it's not nearly as scary Megalodon has
something that the blue whale doesn't
though big teeth in huge jaws take your
hand out and look at it the average
length of an American males hand from
the tip of the middle finger down to the
base of the wrist is 18.9 centimeters
the length of some Megalodon teeth that
have been discovered where eighteen
point four centimeters long so imagine a
dagger as long as that cutting into you
but then you need to realize that
Megalodon had over 250 of those dagger
sites teeth and they were located across
five separate rows inside of their jaws
which could open to be over two metres
across large enough to swallow Dwayne
the rock Johnson hold in one bite the
bite force of these gargantuan jaws has
been estimated to be around 180,000
Newton's which is enough to actually
crush a Toyota Corolla inside of them if
you were unlucky enough to somehow end
up in that situation a scuba diver
unprotected would experience a nightmare
a storm of dagger teeth inside of jaws
that would swallow you whole in one bite
and you wouldn't really be able to swim
away from it either because despite
weighing more than a tank the Megalodon
could probably swim up to eleven miles
per hour faster than even Michael Phelps
his top swimming speed of 6 miles per
hour fossils of Megalodon have been
discovered in oceans and beaches all
across the world so it likely had a
pretty similar range as the great white
does today which means that basically
nobody would be safe watching this video
if it was still around except for the
British apparently whose food is so
terrible if not even sharks will bother
with it
Megalodon existed as recently as 2.6
million years ago and despite what
countless clickbait videos on YouTube
will have you believe No
it definitely doesn't still exist today
no matter what they say but she wasn't
the only monster lurking in the seas
over two and a half million years ago
another beast at least as terrifying as
the shark of sharks also haunted the
ocean then and its name was Leviathan a
monstrous sperm whale just slightly
smaller in size than Megalodon but with
an even more ferocious jaw line
Leviathan had teeth measuring over 36
centimeters long exactly twice as long
as the teeth of Megalodon and the
largest teeth of any creature ever
recorded for millions of years
Megalodon and Leviathan were the apex
predators of the ocean and possibly the
largest predators to ever exist and they
existed at the same time they were
probably fierce rivals and it's
interesting to imagine if any ancient
battles took place between them the
ocean is a scary place to be today but
it used to be a whole lot worse if
you're like me then you've probably
always been excited about and interested
in dinosaurs and other extinct monsters
like Megalodon since you were a kid but
you don't need to go to a museum to
learn more about them right now all you
need is your phone or your computer and
head over to curiosity stream with
