Lions, and tigers, and bears.
Oh my.
If any of them bite you,
do you think you would die?
Their ferocious fangs make them
seem like they have the scariest
bites in the animal kingdom.
But in reality,
there's a lot worse out there.
And today, we're counting them down.
What animals' bites are worse
than their barks?
When it comes to bites,
size doesn't matter.
Some tiny creatures can kill you with
their toxic teeth,
while other large animals
could crush you with their powerful jaws.
More than 700 bacterial species
can live in a human mouth.
If you get bitten by a human,
there's a 10 to 15% chance that
the bite will become infected.
That percentage increases
if your immune system is compromised,
you have diabetes or vascular disease.
And your attacker doesn't need to be
a vampire or zombie
to cause damage.
Although a human bite is only about
1,117 kPa (162 psi),
it can break skin
and damage joints.
Bite wounds are painful.
They bleed,
and the area around it will begin to swell.
You may have also been exposed
to any diseases your attacker has,
such as Hepatitis, HIV or tetanus.
Even if the wound doesn't look too bad,
clean it immediately or pus could form.
Don't wait to go to the doctor.
An infection will rapidly spread
if you don't get immediate medical care.
Living in Central and South America,
the Brazilian wandering spider
is one of the most venomous spiders
in the world.
Unlike most spiders,
they don't build webs to catch their prey.
They actively hunt,
ambush and attack their prey,
which is usually insects, reptiles and mice.
If you come across this spider
and it raises its first two pairs of legs,
back away.
It is letting you know it feels
threatened and will attack you.
If it bites you,
you'll feel extreme pain.
You will drool, sweat
and your skin will swell around the bite.
You'll also have cramping,
vertigo and convulsions.
You'll need to see a doctor immediately
and get treated with anti-venom
and a tetanus shot.
If you don't get help soon, you may die.
King cobras live in the rainforests of India,
Southern China and Southeast Asia.
On average,
they grow to a length of about 4 m (18 ft).
And they can even stand up
and look you in the eye.
Although they try to avoid humans,
this snake will attack you
if it feels threatened.
It will flare its hood
and emit a hiss that sounds similar
to a growling dog.
If a king cobra bites you,
get immediate help.
This snake is extremely venomous
and will inject a large amount of poison
when it bites you.
As little as 6 ml (0.2 fl oz) of cobra venom
can kill 20 people.
Don't apply ice to the wound.
That will only cut off circulation
and make the situation worse.
And don't try to suck out the venom.
Remember what we said about bacteria
in the human mouth?
You could infect the wound.
You will suffer convulsions,
vomiting, and respiratory failure.
You have about 15 minutes to live.
Keep the bitten limb as rigid as possible.
And keep it lower than your heart
so that the venom has to work against
gravity to circulate.
Go to an ER right away.
The saltwater crocodile has
the strongest bite force of any animal,
with a power of 25,500 kPa (3,700 psi).
That's almost 23 times stronger
than a human bite.
They can grow to almost 7 m (23 ft) long
and weigh over 1,000 kg (2,200 lb).
Although they usually prey on turtles,
birds and mammals,
they will attack you
if you invade their habitat.
They can be very aggressive.
Saltwater crocs hunt by hiding along
the edge of a body of water.
These lurkers lunge at any prey that
approaches or enters the water.
They can stay underwater
and hold their breath for up to an hour.
If a crocodile grabs you,
try to gouge its eyes out with your fingers.
The more you hurt it,
the better the chances it will let you go.
And if you get free,
go to a hospital right away.
You're going to need serious help.
Even though they are herbivores,
Hippos kill about 500 people
per year in Africa.
That's more than any other wildlife
on the continent.
They weigh as much as 2,700 kg (6,000 lb)
and have a bite force of
13,800 kPa (2,000 psi).
A hippo can crush your head with its bite
and can even snap a canoe in half.
It may trample you,
drag you into a lake or tip your boat over.
Even if it doesn't bite off your head,
you will have severe trauma.
You could get a deep wound infection
and may need an amputation.
So, if a hippo charges at you,
run as fast as you can up a hill or tree.
Just because these animals
have the most dangerous bites,
it doesn't mean that other creatures
won't try to chomp on you.
Even your pet cat might want a little taste.
Do you know how deadly that could be?
