not what you want to find in your home
welcome to watch mojo and today we're
counting down our picks for the top 10
venomous spiders
a bite could range from a painful
blister to a more serious hospital visit
only the female bite is dangerous and
their bites have caused some human
deaths
one thing is clear you'd rather not be
bitten by one
for this list we're looking at the
world's most dangerous spiders
ranking them according to their
poisonous potential have you come across
any of these spiders
let us know in the comments
number 10. southern black widow spider
while the southern black widow is among
the most well-known and feared spiders
is its bad reputation accurate
this arachnid is relatively common in
certain areas of the united states
females of the species are often
identified by a unique hourglass marking
when she bites the venom takes hold
bringing a slow paralysis
only mature females have large enough
jaws to envenomate humans
bites can cause muscle aches swelling or
even make it difficult to breathe
black widow females have a bad girl
reputation
and with reason after mating
she's hungry and her favorite snack is
her mate
luckily most adults tend to recover but
this spider's venom is still
dangerous to vulnerable groups like
children and the elderly
if bitten they should seek immediate
medical attention
so whatever you do look out for that
tell-tale red hourglass
number nine yellow sac spider
some spiders prefer to mind their own
business and stick to the shadows
however the yellow sack spiders are bold
predators
the rather tiny size of this creepy
crawly allows it to get around easily
this enables it to go from being a
rather irritating garden arachnid to a
persistent unwanted house guest
certain species of yellow sac spiders
can produce a bite that usually results
in swelling
and discomfort but as with most spiders
reactions can vary from person to person
in rare instances a yellow sac spider
could leave its victim feeling sick
enough to want to visit a doctor
number 8 brown widow spider although
it's not as famous as its cousin
the brown widow is still a species to
look out for with striped legs and an
orange hourglass on its body
the brown widow has quite an
eye-catching look fond of tropical
locales and known to hide around
barns and houses the brown widow will
not usually seek out human contact
while the males don't bite the females
of the species will if threatened
some researchers believe that its venom
is much more potent than the black
widows
you can see they're not naturally
aggressive from how they're playing dead
when knocked out of the nest
but they are venomous a bite could range
from a painful blister to a more serious
hospital visit luckily brown widow
spiders bites don't usually deliver
a large quantity of venom number 7.
brown recluse spider it is not what you
want to find
in your home traditionally located in
southeastern and central areas of the
united states
the brown recluse typically comes
stamped with a violin pattern on its
body
and maxed out stealth skills the
spider's name is not simply for show
as the brown recluse sticks to
well-hidden areas and seldom brings
attention to itself
one of the more common ways that people
get bit is
they're in clothing or clutter
inside shoes its venom is necrotic and
can be unpredictable
while some people might end up with
nausea and a reddish mark that fades
without complications
others can develop a blister or a lesion
susceptible to gangrene
luckily the brown recluse doesn't often
bite deeply or
frequently they're actually very
harmless
and if you want to treat them the best
thing to do
is to bring in a professional to treat
your house
and then maintain with flat paper
inexpensive sticky traps to keep a check
on the population
in your house number six red-headed
mouse spider
compared to some other species that call
australia home
the red-headed mouse spider almost comes
across as quaint
it's a black spider with an instantly
recognizable bulging head that is very
red in males
the mouse spider likes to stick to
burrows near water routes
thus making human contact relatively
rare but humans who do encounter it
should remember that this spider has a
highly toxic
venom while a bite from a redheaded
mouse spider has rarely led to severe
symptoms
victims are better off playing it safe
and getting checked out
number 5. six eyed sand spider
found in southern african deserts and
somewhat resembling a crab
the sick side sand spider spends its
days setting traps to eat
insects and scorpions this arachnid
predator is mainly the type to keep to
itself and pretty much wants nothing to
do with humans
its behavior has made bites involving
the species almost unheard of
and that is very much a good thing as
the spider's venom is suspected to be
toxic enough to cause necrosis
killing the tissue around the bite oh
and did we mention there is currently no
anti-venom
although the spider's introverted nature
keeps it from being a threat to humans
it still has enough firepower behind its
fangs to be a danger
number 4. chilean recluse spider
the chilean spider is widely considered
to be the most dangerous arachnid in the
recluse genus
a south american native that's indulged
in some sporadic immigration the chilean
recluse spider has
six eyes and often bears a violin
marking on its thorax
it's very fortunate that this arachnid
lights to keep its distance from humans
because its venom packs a hefty punch
the chilean recluses bite is toxic
enough to result in fatal consequences
if enough venom is injected
but even in less severe cases the
spider's venom is necrotic and can lead
to loxacilism
a condition that can take months to heal
number three
redback spider now for another
australian resident
also known as the australian black widow
the red back is from the same genus as
the widow spiders earlier in our list
the female of the species has a red
stripe on its body
is considerably larger than the male and
has way more dangerous bites
the red back possesses a potent
neurotoxic venom
only the female bite is dangerous and
their bites have caused some human
deaths
although they don't go out of their way
to attack humans redback spiders have
been known to settle down in areas that
bring them
into contact with people and what's
brought it here
is the extraordinary way in which it
uses silk
this makes biting incidents much more
likely their toxin is known to cause
intense pain
and other symptoms like nausea and
sweating fortunately an
anti-venom introduced in 1956 has helped
lower the chances that these spiders
will strike a
fatal blow number 2 brazilian wandering
spider
it's best to stay out of this spider's
way when it goes on a stroll
a proactive hunter the brazilian
wandering spider is hairy
large and extremely venomous it's called
a wandering spider and the reason it's
it's called a wandering spider is it
doesn't build a web
it just continually wanders in search of
food instead of just keeping up webs
this species goes for walks and finds
its prey
the spider's bite can produce a range of
alarming symptoms including hypothermia
vertigo and convulsions in humans
these guys have a really nasty venom it
actually kills a number of humans every
year
if enough venom is injected the wound
could be life-threatening
this potent weapon makes the wandering
spider a hunter of incredible power
able to kill insects lizards
and mice animals as large as the spider
itself
fortunately the brazilian wandering
spider only tends to bite humans with a
relatively low amount of venom when it's
provoked
and if you have a bad encounter with
this arachnid an anti-venom
does exist one thing is clear you'd
rather not be bitten by one

number one sydney funnel web spider
funnel web spiders have earned quite a
nasty reputation
however not every species is equally
dangerous
while the northern tree dwelling variant
should be taken seriously
the one you should really worry about is
the infamous sydney funnel web spider
and the key to its reign are these
[Music]
two of the biggest most powerful jaws in
spider land
backed by super venom inhabiting the
area around
sydney the capital city of new south
wales in australia
these spiders like to dwell in humid
habitats
like most spiders they usually only bite
humans when feeling threatened
but that knowledge will probably be of
little comfort to its victims
to work these daggers they must raise
their bodies up
and strike down they often clutch onto
their target
and bite again and again the potent
venom from males can cause
intense pain muscular twitches and
disorientation
in worst case scenarios a sydney funnel
web spider's bite can be fatal
if it's not treated now that venom is a
neurotoxin and if you do not receive
medical attention you're bitten by a
male sydney funnel web spider
you are most likely if not definitely
going to die
so definitely seek medical attention do
