Sure,
exploring the African
savanna can be deadly.
But have you heard that growling sound
coming from across the street?
Could your furry friend
curled up on your couch
turn on you?
Or perhaps there's an eight legged
killer lurking in your garden.
Maybe the danger isn't as far away
as you thought.
We've shown you a lot of deadly creatures
here on How to Survive,
but we can't forget
those in our own backyard.
They can be your best friend,
but also a worst nightmare.
From 2005 to 2017,
dogs killed 433 people in the U.S..
Most of these deaths
were caused by pitbulls.
Dogs aren't inherently violent,
but if they feel threatened or scared,
they won't hesitate to bite you.
Pay attention to warning signs
such as barking,
growling or snapping at the air.
If an attack is imminent,
the dog will go for your neck,
head, or chest.
So you need to protect these areas.
If possible,
try to get the dog to bite an area
that is well-protected
like your bulky coat or shoe.
The mix between African queen bees
and European worker bees
has formed a deadly hybrid,
Africanized bees,
a.k.a. killer bees.
The name fits
since they seem to attack
more aggressively than local honeybees.
These swarming renegades
are found across the U.S.
and Mexico,
along with South and Central America.
They're incredibly persistent.
If they perceive you as a danger,
they will chase you for up to
400 m (1,300 ft).
Your best bet
is to not move around
if you spot a hive.
Bees interpret quick
or jerky motions as threats.
And if you get stung
by one of these cruel buzzers,
you're in deep trouble.
Their stingers release pheromones
which signal to other bees
to mount a defensive attack.
Then you'd have the whole hive after you
Often called mountain lions or cougars,
these muscular and notorious hunters
can bring down animals twice their size.
Pumas feed on deer, elk and sheep,
but if you're on their territory,
you're fair game and easy prey.
If you come across this cat, don't run.
That'll be interpreted as prey behavior
and then it'll chase after you.
Instead, try to maintain eye contact
and make yourself look bigger
by raising and spreading your limbs.
Don't make any loud noises,
and slowly back away.
While visiting the breathtaking
coastal areas of South Florida,
you might run into something
that can literally take your breath away.
This 4 m (13 ft) long alligator
will eat fish,
turtles, snakes,
or practically anything else that moves.
It can camouflage itself
in cypress or freshwater swamps.
So chances are
you won't even spot it
until it's too late.
If you come face to face
with the crocodile, stay still.
Avoid sudden movements or splashing.
If it begins to chase you,
run away in a straight line.
The myth about running in a zig-zag
is just that,
and could be a fatal mistake.
If it clamps down on you with its jaws,
quickly jab its eyes with your fingers.
That's the crocs most vulnerable area.
and will improve the odds
of it releasing you.
These iconic hourglass-shaped
shiny spiders
are found throughout the U.S.
and areas of Canada.
Their bite is often just a minor pinprick,
so you might not feel it at first.
Give it a few minutes
and you'll start to experience
pain in your chest and abdomen.
Muscle spasms will follow
and breathing could become
almost impossible
due to paralysis of your diaphragm.
Always check inside your shoes
before putting them on.
If you're bitten,
wash the side with soap
and getting medical help right away.
This is no teddy bear.
Weighing up to 363 kg (800 lb)
and packing a bite force
that rivals that of a lion’s
grizzlies can rip apart flesh,
bones and almost everything
that’s in their path.
They typically attack humans
by tossing or pushing them around,
then wait to see if they get up.
Because of their size,
grizzly bears are hard to miss.
You'll hear them if they're near,
and if they start charging you,
play dead.
Lay down flat on your stomach
and spread your legs apart.
Make sure to cover your head and neck
with your hands and arms.
If you see a tree nearby, climb it.
Unless it's desperate for food,
an adult grizzly
won't put in the effort to follow you up.
The beautiful blue waters
of Volusia County, Florida,
hide a dark secret.
The region has had
333 shark attacks since 1882.
If you've been to the beaches there before,
chances are you've been within 3 m (10 ft)
of a great white shark.
If this 2,268 kg (5,000 lb) predator
mistakes you for a snack,
be prepared to punch its eyes and gills
with all you've got.
These are its most sensitive spots.
This slithering creature
only has enough venom to kill reptiles,
birds and small mammals,
but you'll still get an excruciating bite
if you step into its territory.
If this happens to you,
remove any tight clothing or jewelry
to prevent the wound from swelling
and get medical help as soon as possible.
In the meantime,
allow the wound to bleed
in order to flush out some of the venom.
Whatever you do, don't wash it.
Doctors will need
some of the venom to confirm
you were bitten by a prairie rattlesnake
and get you the anti-venom you need.
It might look like a laid back animal,
but the biggest of the deer family
is anything but.
Moose are extremely territorial
and can become aggressive
if you try to feed them
or come too close to their offspring.
Males can weigh up to 700 kg (1,543 lb),
making a collision with them deadly
whether you're on foot
or behind the wheel of a car.
If you encounter this beast,
you best keep your distance.
If that doesn't work
and it starts charging at you,
run.
Head for big trees or rocks,
anything to duck behind.
After fighting off
all these ferocious
North American creatures,
you'll need to take
a well-deserved vacation.

the beautiful country
where almost everything that moves
can kill you.
Even this tiny thing.
