From powerful attackers to insane hunters…stay tuned to number 1 to find out the most venomous
spiders on the planet.
Number 10: Indian Ornamental.
Don’t be fooled by this creature’s name: it only sounds like an ornament but, believe
This species of spiders, coming from India, as the name suggest, belongs to the group
of arboreal tarantulas…and they lead a very “defensive” lifestyle.
As far as its venom is concerned, it is quite dangerous.
Although there haven’t been any fatal occurrences recorded, the Indian ornamental can have a
very strong bite, causing intense pain when they inject venom into the victim’s tissue.
As we said, they are not aggressive by nature, and they would rather run away and hide in
some place than attack and fight.
The problem arises when they are cornered; in these moments, Indian ornamental doesn’t
think twice…as their only way out is to strike a blow.
Luckily, they only live in India! (uhhh…Indians, watch out!)
Number 9: Redback Spider.
These beauties originally come from Australia, but they can now be found in some parts of
Asia, as well as New Zealand.
It is known for its very powerful venom, produced by the glands in its mouth.
The reason why this venom is so powerful is because it contains some very strong enzymes
and several harmful toxins, especially the one called alpha-latrotoxin.
This one is particularly strong, and it causes severely intense pain in humans; it destabilizes
cell membranes and affects the nervous system, but also causes some cardiovascular manifestations
in some people.
Because of the spider’s small size, it’s usually very hard to find the place of the bite, as
there is no swelling or puncture marks.
And the pain is not very strong at the beginning…the victim only feels slight stinging or a sense
But after about an hour, the symptoms start to kick in: goosebumps on the skin, sweating,
and severe pain at the place of the bite.
Sometimes, there is also pain below the knees or a sense of burning in the feet.
All in all…pretty unpleasant.
Number 8: Sydney Funnel-Web Spider.
Australia is known for its dangerous creatures, and their spiders are no different.
But, before we meet this funnel-web spider, take a moment to like this video and subscribe
It’s really important that you click the little notification bell, too, so you can be notified
each time we post a new video!
This Australian spider’s body contains atracotoxin, and because of this…it is very toxic for
humans and other primates alike.
When they bite, funnel-webs usually bite repeatedly, because it’s in their defensive mechanism.
Hence, the area of the bite can sting quite a bit.
Strangely enough, the female doesn’t bite that much, compared to the male.
Usually, when a funnel-web bites, it takes up to one hour before the first symptoms can
be felt…but it averages around 30 minutes.
Children are especially vulnerable when it comes to funnel-web bites.
Almost one half of those bitten by these spiders are children, and there has also been one
case reported of a child passing away in less than 15 minutes after being bitten by a funnel
The bite of this spider is considered very dangerous, and it requires immediate medical
attention and hospital treatment.
Number 7: Brazilian Wandering Spider.
When you hear “Brazil,” you usually think about something exotic and exciting, but in
this case…you should be alarmed.
Although it may be exotic and exciting, it’s also quite scary.
We’re talking about two species of Phoneutria spiders, usually referred to as the Brazilian
Sometimes, the whole genus takes on the reference, but it should be said that not all Phoneutria
species come from Brazil.
These spiders have a very powerful neurotoxin, which affects the nervous system in victims.
If a high concentration of the venom is injected, it will cause breathing problems and muscle
control, which may even lead to paralysis.
There may also be severe pain, inflammation and other side-effects.
In this spider species, it’s the female that usually has more venom in the body.
The amazing thing about Brazilian wandering spiders is that they prey not only on smaller
insects, but also small animals such as lizards and frogs.
They can be dangerous to humans, but their bodies have a drawback: their jaws simply
aren’t made for bigger bites.
Well, that’s a relief!
Number 6: Wolf Spider.
Wow, this sounds intimidating, judging by the name.
And indeed it is.
This type of spider is interesting because of the fact that it doesn’t spin webs, like
the majority of spiders.
The name “wolf spider” comes from the fact that they prey on their potential food by
stalking it, just like wolves.
They are loners by nature, and possess excellent hunting instincts.
They live in different kinds of terrains, but prefer forests, meadows, woodlands and
But they rarely stay at one place; usually, they wander around in search of food, without
a permanent hiding place.
Wolf spiders are not aggressive by nature, so there’s no fear of them biting first; however,
if provoked on a continuous basis, they will strike and attempt to inject their venom into
the victim’s body.
Some of symptoms might be itching, mild pain and swelling.
The spider’s fangs are pretty strong, and they can tear the skin easily, infecting it
and causing swelling in lymph nodes.
The best treatment for wolf spider bite is proper cleaning and icing to relax the area.
The symptoms will usually go away after about ten days and, in most cases, there is no need
for medical attention…only when a small child or an elderly person has been bitten.
Number 5: Black Widow.
Here it is – the most infamous of all venomous spiders.
But, it’s not the most venomous, because the competition is fierce.
The bad rap black widow has been receiving occurs because of several factors, only one
of which is its bite and venom.
However, what turned this spider into one of the most hated monsters in the animal kingdom
is the fact that, after mating…the female tends to kill and eat the male.
Not the prettiest of ways to say “I love you,” sure.
On the other hand, although many people fear the very mention of the black widow, it turns
out that its venom is not that dangerous to us humans.
What is interesting is that, although black widow venom can have an effect on a human,
only female spiders are able to “envenom” the victim; the mouthparts of a female are
the only ones big enough to strike a venomous blow…the males simply aren’t that big.
When a black widow bites a person, what occurs is a condition called “Latrodectisim;” the
symptoms of this are sweating, vomiting, pain and rigidity in the muscles.
But this condition almost never results in a fatal outcome.
It is known that some pets, such as cats, have not made it, as a result of muscles paralysis,
but it’s extremely rare in humans.
Number 4: Red Widow Spider.
And you thought that the Black Widow was scary?
Wait to see this one.
The red widow spider lives in central and southern Florida, usually in sand dune areas.
Just like its black cousin, it has a powerful sting that can result in Latrodectisim, but
the bite itself is rarely fatal.
Not many people know about the red widow, because it’s not one of the most common spiders
around, yet its venom is a force to be reckoned with.
Scientists claim that red widow’s venom is…wait for it…10-25% stronger than a rattlesnake’s
Yes, it’s that serious!
However, you can breath a bit, because the concentration of the venom is so low that
it’s not typically fatal.
After the bite, the victim will feel muscle spasms and sweating, vomiting and a rise in
blood pressure, as well as severe pain…but fatal occurrences are rare.
Unless the victim is a child or an elderly person…in which case, in could prove highly
The worst part happens in the first 12 hours after the bite; as hours go on, the symptoms
Number 3: Goliath Birdeater.
What a name.
It sounds just like a horror B-movie from the 1950s.
Well, the name is definitely deserved, because this type of tarantula is really impressive.
Originally from South America, the Goliath birdeater is the world’s second largest spider,
by size and mass.
In fact, it makes an appearance in our video about the largest spiders in the world!
I know what you’re all thinking: “Does it really eat birds?”
No, not really.
Scientists say that this type of spider very rarely preys on birds; that’s not something
you would expect out of a Goliath birdeater.
The reason why it’s called that is because of an engraving from the 1800s, on which the
spider was shown eating a hummingbird.
Maybe it’s artistic license, or maybe it did prey on a bird, but really, this is just a
cool sounding name.
It has powerful fangs, and it can pierce through the skin, but it’s relatively harmless, because,
luckily, its bite is more like a wasp’s sting…not that bad.
However, what makes the Goliath birdeater amazing is that it actually has three lines
of defense, fangs being just the first one.
It can also rub its legs together, creating a hissing sound that can be quite scary and…listen
to this…it can also rub its legs against its abdomen, and this will result in the release
of tiny hairs that can reach the eyes and the mucous membrane, causing extreme itching
and pain that will last days.
Number 2: Chilean Recluse Spider.
This is one of the most dangerous and most venomous spiders from the family of so-called
Its bite is very strong and extremely venomous.
Experts claim that one bite can cause major allergic reactions, and even expiration.
Like so many spiders, the Chilean recluse is not aggressive by nature; it never attacks
first, but if it happens to be pressed against human skin, it won’t think twice before responding
with a mighty bite.
Its venom contains a special agent, which can cause skin necrosis.
Many studies have shown that the Chilean’s venom is one of the most powerful, if not
the most powerful of all venomous spiders.
Once the victim has been bitten, the symptoms can vary in number and scope, from light irritation
on the skin to skin ulcers and the destruction of the soft tissue.
If this happens, it can take months before the tissue heals; in rare occasion, it takes
even years, after which there are major scars visible.
And the effects usually don’t kick in right away, but can take a few hours before they
Number 1: Six-Eyed Sand Spider.
So, here it is.
The grand prize.
The most venomous spider in the world.
The six-eyed sand spider.
It lives in the sands of Southern Africa, but it’s not that easy to find.
And there’s one problem with it: nobody can be positive that its bite will actually take
a person out, because there is no evidence, of any kind, that the six-eyed has ever bitten
or taken out a human.
There are a couple of instances, when it was suspected that a six-eyes could have been
the culprit…but it has simply never been proven, to this day.
However, experiments conducted on lab rabbits proved that the venom from a six-eyed sand
spider can work within 12 hours upon victim of envenomation.
The venom itself is so strong that it can cause a range of medical problems, from tissue
destruction and blood thinning to blood vessel leakage.
What makes this spider and its venom even more creepy is the fact that…there is no
