indigenous to the reefs of the Indo-Pacific, and it's the most deadly of over 500 species

of cone snails. There is no known anti-venom, and treatment includes simply keeping someone

alive until the toxins wear off. It has been nicknamed the "Cigarette Snail" because its

believed that a person stung by one would have enough time to smoke a cigarette before

dying.

What The FAK: The facts and knowledge on Deadly Animals.

A single bite delivered by the Inland Taipan can kill up to 250,000 mice and has strong

enough venom to kill 100 adult men, and it has has the ability to kill someone within

45 minutes. Found in Australia, it claims the top spot as the most venomous snake, but,

luckily, it's shy, making human bites nearly non existent. Hospitals equipped with anti-venom

have kept the death toll to zero known deaths from this particular snake, nicknamed the

"Fierce Snake" because of the potency of the venom, and not the behavior.

The Stonefish is one of the most venomous fish known in the world. They are found in

the Indo Pacific Ocean but can also be found in Florida and the Caribbean. It has thirteen

stout spines in the dorsal fin which can inject a highly toxic venom that causes intense pain,

tremendous swelling, temporary paralysis and even death if not treated quickly. They are

able to live out of the water for up to 24 hours and they blend into the background often

looking like an encrusted rock or lump of coral so they are commonly stepped on making

stonefish anti venom the second most administered in Australia.

The Tsetse Fly is a bloodsucking fly found in Africa that transmits the parasite causing

what is commonly known as Human Sleeping Sickness. It can drink twice its weight in blood at

every meal, and once an infected fly bites you the infection quickly spreads through

your blood. It is fatal if untreated and between 300 and 500,000 people are estimated to suffer

from the disease. The flies are hard to control and, unlike most biting flies where only the

female feeds on blood, both males and females are blood suckers.

The Box Jellyfish developed its powerful venom to instantly stun and kill prey so their struggle

to escape wouldn't damage the delicate tentacles. It has venom considered to be among the most

deadly in the world, and it is said to be so painful that many victims die from going

into shock and drowning after being stung. They are found primarily in the coastal waters

off northern Australia and throughout the Indo Pacific. Each tentacle has around 5,000

stinging cells and, depending on the location of the sting, can cause severe symptoms, including

cardiac arrest. Vinegar is said to inactivate the remaining stinging cells left in the skin,

and many Australian beaches have a bottle stored on the beach next to warning signs.

The Box Jellyfish has a tiny relative found in the same area that causes severe pain and

is nearly invincible. Called Irukandji, the name refers to any species that causes the

same symptoms- the exact amount of species that can cause them is still unknown. Though

it is not as deadly as the larger Box Jellyfish, the pain is excruciating and there is no anti-venom.

Symptoms include lower back pain, muscle cramps, sweating, nausea, and can last up to a week.

Many patients require large doses of morphine to get them through the pain, but there are

actually few known deaths from these little guys.

The Brazilian Wandering Spider held the Guinness world record for "Most Venomous Spider" in

2007, and is still believed to hold that title. They originated in Brazil but are found throughout

South and Central America. Brazilian Wandering Spider is actually a generic name for eight

species that belong to the same genus. It wanders all over the place searching for prey

and does not wait in ambush like a majority of spiders. It is not afraid of humans, and

shows a defensive posture by standing on its back legs and will attack when needed. Its

bite can be one of the most excruciating of all spider bites because it has very large

fangs. Oh yeah, it also causes men to have long lasting and painful erections.

The Blue Ringed Octopi are tiny and the most deadly of all cephalopods. Their common name

comes from the bright blue rings that come to life when threatened. Though humans are

rarely bitten, there is no anti-venom and life-saving efforts have to be put into place

until the toxins wear off. If bitten you'll feel nauseous, possibly go blind, lose sense

of touch, speech, and the ability to swallow, and within 3 minutes paralysis sets in and

your body goes into respiratory arrest. Constant CPR is needed to keep the heart pumping until

the body is able to breath on its own. And it carries enough poison to kill 26 adults...So...don't

touch it.

Before the advent of the anti-venom the Black Mamba bite was 100% fatal. Most snake's venom

travels slowly through the blood allowing time for them to get treatment, but the Black

Mamba venom starts within 20 minutes and can be fatal in only six hours. They are found throughout

most countries in sub Saharan Africa, can reach up to 14 ft in length, and travel up

to 12 MPH. They generally avoid humans, but, if threatened, they are fast, highly aggressive,

and often raise a third of their bodies off of the ground, then strike repeatedly if the

attacker persists.

The creature that causes the most deaths among humans is pretty small, really annoying, and

not nearly as intimidating as the others. The Mosquito causes millions of deaths world-wide

every year from transmitting malaria, yellow fever, encephalitis, and west nile virus.

I'm gonna leave you with this Scorpion, considered one of the deadliest in the world, whose toxins

are being used to fight brain cancer.
