what is the deadliest spider in the whole world?

Answer 1

This question seems to be asked very often. The
answers so far given are partly wrong. First, the
daddylonglegs is not a spider (although there is
a spider sometimes called the daddylonglegs
spider). The real daddylonglegs (in the U.S.) is in
a different order of arachnids from spiders, and is
NOT poisonous, though it secretes an unpleasant
smelling secretion as protection from predators.
In Britain what is called daddylonglegs is an insect,
a crane fly.

There are only few spiders that are dangerously
poisonous to humans, and even most of them are
not really "deadly". The brown recluse and its
relatives produce a necrotic wound, that is, the venom kills tissue, making a purple to black spot
that in the case of a serious bite may require a skin
graft. The death rate from recluse bites is about
zero. Supposedly a couple of people have died
from such bites, but firm evidence is usually absent.

The black widow has a neurotoxin that attacks the
nerve centers controlling the heart and lungs, and the nerve-muscle junctions, causing rapid shallow
pulse and breathing and muscle cramps and spasms. The mortality rate from black widow bite
is about 2-3% of reported bites (not all get reported), and the deaths are usually of children or
adults with circulatory or respiratory problems.

I don't know what the death rate is from funnel-web
spider bites or from Phoneutria, the wandering
spider from tropical Americas, but it probably is
quite low. The danger to life from spider bites
and scorpion stings is vastly over-rated.

Answer 2

The world's most venomous spider is the Brazilian wandering spider (Phoneutria nigriventer), but the deadliest spider in the world is the Sydney Funnel-Web Spider. The Sydney Funnel-Web Spider creates a toxin called atraxotoxin, which is one of the deadliest toxins to a human created in the animal kingdom.

The male Funnel Web Spider is six times more toxic than the female...yikes.

Answer 3

The deadliest spider is the daddy long legs. Although he is the deadliest their mouths do not open enough to be able to bite

Answer 4

Australian Funnel Web Spider.

Answer 5

in case you've faith the Noah's Ark fable, I actually have a bridge in Brooklyn i opt to promote you. the most wise element on your question changed into the remark about the animals close to the Indian Ocean sensing difficulty beforehand the tsunami...certain, they do. And if some similar flood changed into immanent in biblical circumstances (i'm particular there have been plenty), the critters may were merely as delicate then as they at the instant are. they could have headed for prime floor lengthy beforehand the people figured issues out -- survival instinct, through organic selection and sharpened by using thousands of thousands of years of evolution.

Answer 6

Untreated, the brown recluse. Look up photos of the damage a small bite can cause.

Answer 7

I would say the brown recluse because if left untreated, their bite can cause Gran-green.

Answer 8

Brown Recluse we have them down her in Vegas, and they take lives every year. There venom is flesh eating.

Answer 9

If you are talking about 'to humans' the answer would be Brown Recluse I believe.

Answer 10

Daddy long legs have very mild poison.

Brown recluses are very poisonus, but I don't know if they're the most poisonus.
