Question

What is the most aggresive and deadly spider in the world?

Answer 1

The Brown Recluse. There's no reason why this little guy has to be so mean.  Looks a bit like a black widow but it's sandy brown.

Answer 2

this question comes up all the time, and there are many different ways to answer it.

the most agressive species of spiders are probably the sydney funnelweb spider or the infamous black widow.

the spider with the deadliest venom however is the Brazillian Wandering Spider, more commonly known as the Banana Spider (it is commonly called the Banana Spider because they are sometimes found hiding in crates of bananas that havent been properly inspected and shipped off to other countries).

the spider responisble for the most human deaths however is the black widow.

Answer 3

Well, you can have an aggressive spider that isn't deadly, and you can have a deadly spider that isn't aggressive.

Probably the worst spider with a combination of both of those things is the Banana Spider of South America.  It lives in the tropical jungles of the Amazon.  It's a very large yellow and black spider that hunts among the plants and trees.  It very rarely bites humans, but IS extremely aggressive AND with a powerful venom.  

There are a few species of Tarantulas that are very aggressive and will rear up and lurch forward at the slightest provocation, but their venom is no worse than a bee sting. Then there's the Black Widow Spider which is very docile, and takes a lot of harassing to get it to bite, but its bite will put you in the hospital in pain.

99.9% of all spiders are harmless to humans. They do our world a great deal of good, and bring beauty and diversity into our lives.  If it were not for spiders we'd be overrun with insects, other spiders, and many other pests.  Spiders around your home help rid you of Flys, Aphids, Cockroaches, Crickets, Termites, Gnats, and other pests.

Answer 5

The guy who used to be in Coronation Street, he had a very aggressive hairstyle and a deadly looking nose combined with a terrifying mole on his cheek.

Answer 6

It 's an age old question and I'm sure you'd like an answer, well here goes:

This is a rather difficult question to answer as there are actually a number of very venomous spiders in the world, all of which have caused human deaths (in some cases the reported cases are anecdotal rather than scientifically recorded).

Of those, the Black Widow Spider (Lactrodectus mactans) of North America is the most well known of the so-called deadly spiders. Other members of the Lactrodectus family are found throughout many temperate parts of the world, such as Australia where it is known as the Red Back spider and New Zealand where it is known as the Katipo spider.

The Sydney funnel spider (Atrax robustus) of Australia is often quoted as being the spider with the most dangerous venom.

On the other hand; according to the Guinness Book of Records the world’s most venomous spiders is the Brazilian wandering spider (Phoneutria nigriventer).

This spider is believed to have the most active neurotoxic venom of any living spider. Its venom is so potent that only 0.006mg (0.00000021oz) is sufficient to kill a mouse.

Answer 7

Well im not sure whats the most aggressive, but the confirmed most venomous spider is the Brazilian Wandering Spider.

Answer 8

The Brazilian Wandering Spider

The Brazilian Wandering Spider is very fast, extremely venomous, nervous, and aggressive. This large and dangerous spider is grows to five inches long, and is ranked among the most venomous spiders known to man.

This spider is believed to have the most active neurotoxic venom of any living spider. Its venom is so potent that only 0.006mg (0.00000021oz) is sufficient to kill a mouse.

This Spider is often referred to as the "Banana Spider" because there have been cases where these spiders unintentionally appeared on banana boats heading for the United States from tropical, and subtropical regions of South America.Tarantulas are commonly found during banana inspections.

The problem arises when some of these spiders manage to go unnoticed and begin weaving their webs in our unsuspecting neighborhoods.They can breed and proliferate until they cannot be controlled.

Answer 9

Black Widow spider I think

Answer 10

According to the Guinness Book of Records the worlds most venomous spider is the Brazilian Wandering Spider.

Answer 11

Others have mentioned the most venomous spiders, but I just wanted to add a bit about an aggressive spider. I have only ever seen two spiders that I would consider to be aggressive, and they were both male Mouse Spiders, on two separate occasions, in different places (so it wasn't the same one twice. lol). Both of them actually chased me for no apparent reason. I can tell you I was not hanging about to see what would happen if either of them caught me.

Here's a pic.
