and there's the little beauty welcome to
watch
mojo and today we're counting down our
picks for the top 10 most venomous
animals
kitty weed may be innocuous but boom
slang skin
it has hemotoxic venom small amounts
cause hemorrhaging
even death even in humans one thing is
clear
you'd rather not be bitten by one for
this list
we're looking at animals that inject the
deadliest toxins into their victims
we're taking into account their danger
to humans and
their venom's median lethal dose or ld50
for short
the lower that number the deadlier the
venom
which one of these critters scares you
the most let us know in the comments
below
number 10 the brazilian wandering spider
wander wherever you want buddy just
don't come where we live
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 the
brazilian wandering spider is frequently
called the deadliest in the world by the
famous guinness book of world records
these guys have a really nasty venom it
actually kills a number of humans every
year
and if you live in south america there's
a very real chance it might
wander by your home their nomadic habits
and numerous habitats mean they can
easily stumble into residential
neighborhoods
thankfully they don't seem to bite
humans very often
when they do they usually don't inject
enough venom to kill
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
that's surprisingly merciful for a
creature whose venom has an ld50 of
0.134 milligrams per kilogram
meaning that 50 percent of test subjects
are killed from just
.134 milligrams of venom per kilogram of
body mass
that's many many times more toxic than
cyanide
and we're just getting started one thing
is clear you'd rather not be bitten by
one
number nine the boom slang killiweed may
be innocuous but
boom slang skin turns out that boomslang
is more than just a silly name for a
potion ingredient in harry potter
it's actually the name of a very serious
snake that
honestly looks kind of adorable the way
to tell is a bomb sign's got a very
blunt shaped nose shaped head
and big big eyes got excellent eyesight
these snakes
but boom slangs can kill you with an
average
ld50 of around 0.1 milligrams per
kilogram
found in the african savannah boom
slangs like to hide in trees and shrubs
waiting to prey on animals like birds
and chameleons
it has hemotoxic venom small amounts
cause hemorrhaging even
death even in humans so it might be a
good idea to look
twice before you climb up for that
perfect photo of a herd of zebras
if you do get bitten don't panic the
venom works slowly
and there is an anti-venom you should
have
several hours to get help number eight
russell's viper
with an ld50 of 0.133 milligrams per
kilogram
the venom of russell's viper isn't much
more potent than the boomslang
but it kills a lot more people why
location location location the boomslang
is a pretty relaxed snake
and doesn't hang out in places humans
tend to go but russell's viper is
aggressive widespread in india and
tends to appear near populous areas
there have been
more than a few cases where people have
run into them while headed to outdoor
bathrooms at night
and considering how venomous russell's
vipers are
a bite after dark can be a very
dangerous occurrence
number seven the many banded crate
found in marshes throughout china and
southeast asia
the many banded crate prefers to be left
alone
you probably won't have to see the
distinctive bands it has on its body
if you don't go looking for it but if
you do end up startling a many banded
crate
you'd better watch out admittedly it's
not nearly as harmful to people as its
much more aggressive cousin the indian
crate
but that's not because it's venom is
weak in fact with an ld50 of .09
milligrams per kilogram
this snake can easily be fatal to
victims that don't get treatment
luckily the many bended crate tends to
be timid
number six the south american
rattlesnake
if you thought north american
rattlesnakes were bad wait until you
hear about the ones that live south of
the equator
south american rattlesnakes are found
just about everywhere in the continent's
lowlands
although they're not particularly
aggressive to humans
that widespread range is frankly a
little scary
why because with an ld50 of 0.478
milligrams per kilogram
their bite tends to kill over 70 percent
of the people who
don't receive anti-venom but those who
get treatment are not safe
a shocking 11 percent of people who
receive anti-venom still perish
so even with medical help a bite from
this rattler has around a 1 in 10 shot
of killing you
at least their rattlers might give you a
fair warning before they bring the pain
number 5. the dubois sea snake ask
any serious snake enthusiast and they
will tell you sea snakes have a
reputation for being
particularly deadly but that's only
partly true
human deaths from sea snake bites are
actually quite rare
since these real-life sea serpents tend
to be pretty chill
when they do bite humans they tend to do
it dry
meaning they don't inject their venom
after all why
waste some perfectly good death juice
when they could just scare you away
but if you do get one mad enough to bite
you properly good luck
sea snake venom is ridiculously potent
with an
ld50 of .044 milligrams per kilogram
the dubois sea snake is the deadliest of
the species
it's also the third most venomous snake
on earth
yeah there's more coming number four the
box jellyfish
they can be beautiful while in the water
but box jellyfish can pose a cautionary
tale for unassuming swimmers
and beachgoers let's step away from
snakes for a minute and check in with
another deadly creature
boxed jellyfish may not look like much
but you should not judge a book by its
cover
they can get surprisingly mean for a
creature that appears so squishy
what makes them so dangerous to man are
their tentacles
an adult box jellyfish can grow up to 40
of them
and each one contains around 5 000
stinging cells
a species of the box jellyfish known as
the sea wasp
has an ld50 of .04 milligrams per
kilogram
making its venom as potent as any sea
snake its sting can also cause intense
pain and even send swimmers into cardiac
arrest
before they reach the shore even
patients who get treated with anti-venom
can be left in pain for up to two weeks
number three the eastern brown snake and
there's the little beauty
all right it's time to get back to
snakes but what a reptile the eastern
brown snake is
initially it may not look or sound that
intimidating
but despite its bland name and color
scheme it can very much kill you if
you're not careful
like most snakes the eastern brown is
shy
but catch it off guard and it doesn't
hesitate
to strike we're not kidding
thanks to its potent ld50 of .0365
milligrams per kilogram
and a tendency to thrive in human
populated areas
the eastern brown snake is responsible
for around 60 percent of snakebite
deaths in australia
on a continent known for its venomous
snakes the fact that this creature kills
more people than any of its relatives
is terrifyingly impressive number two
the inland taipan you didn't think we
were done with australia did you
if you've been bitten by a taipan snake
you have to think
fast her strike is incredibly fast and
devastatingly accurate
are you on the coast or inland why would
it matter
because when it comes to the taipan
snake that venom
may be more dangerous depending on your
location it's estimated that one bite
delivers enough venom to kill at least a
hundred
fully grown humans the inland taipan's
venom is more dangerous than its coastal
cousin
with an ld50 of 0.025 milligrams per
kilogram
it's one of the most venomous snakes in
the world the venom is is very complex
but the main constituent part is what's
called a neurotoxin
that is a toxin that affects the nervous
system
and it's very very fast acting
thankfully they prefer to spend most of
their time
underground to avoid the scorching heat
of the australian sun
making bites rare since it's more likely
to run than fight unless you corner it
don't put this snake in a corner well
that hasn't happened to me before
or anybody else anybody alive that is
just think
the deadliest snake on earth came up and
gave me a lick
good thing she didn't like the taste
much before we unveil
our top pick here are some honorable
mentions
the maricopa harvester ant with an ld50
of 0.12 milligrams per kilogram
the world's most venomous insect
the king cobra with an ld50 of 1.28
milligrams per kilogram
for instant recognizability at this size
you kind of expect it to be a python
but it's not it is
the largest venomous snake in the world
the assassin caterpillar
with an ld50 of 0.19 milligrams per
kilogram
the world's scariest inchworm
the funnel web spider with an ld50 of
0.16 milligrams per kilogram
second place in the arachnid category in
terms of temperament
the sydney funnel webs are just
ill-tempered
cranky spiders it's the grumpy old man
of the bug world
the blue crate with an ld50 of 0.1
milligrams per kilogram
almost as deadly as its many banded
cousin the malayan crate is one of the
few asian snakes carrying a purely
neurotoxic venom
as a nocturnal hunter it stalks its prey
in darkness by following scent trails
often entering through an open window or
door before we continue

number one the geography cone snail it
looks harmless
but appearances can be deceiving what
that little thing
surely you just but if you see a shell
like this at the beach
it's one that you absolutely do not want
to pick up
cone snails can lash out with a literal
barbed harpoon the size of a hypodermic
needle
to inject a venom with an ld50 of
between .012
and .03 milligrams per kilogram
there's not even an anti-venom for its
toxin fish hunting snails are
particularly dangerous with venom strong
enough to kill a human
if you get stung you've just got to go
on life support until the toxins wear
off
they typically inhabit shallow reefs in
the indo-pacific
instead of trying to pick up this shell
you should just bring home a novelty
t-shirt
