The Fierce Snake (Oxyuranus microlepidotus) from Australia has, drop for drop, the most poisonous venom of any snake in the world. The first live specimen was not captured until 1975 and not much is known about its habits. The Fierce snake's venom is extremely toxic and a small animal would die within seconds, its nervous system and heart instantly paralysed. The Fierce Snake's venom is more than fifty times as potent as the Indian Cobra's. The maximum yield recorded for one bite is 110mg. That would be enough to kill over one hundred people or quarter of a million mice. The Fierce Snake only lives in an isolated area around where the South Australian, New South Wales and Queensland borders meet. It is usually most active in the early half of the morning when it basks. In cooler weather, it is also active in the afternoon; in hot weather it becomes nocturnal. The Taipan (Oxyuranus scutellatus) was thought to be the world's most venemous snake until the discovery of the Fierce Snake, its cousin. The Taipan lives in the far North of Australia and down the Queensland coast, and has been found in Western New South Wales as far South as the Murray River. The Taipan is an agressive hunter, moving at high speed through grasslands with ease. On finding its prey by scent, it flings itself at the victim and inflicts several rapid bites. Like most other venomous snakes, the Taipan uses its venom sparingly. As they don't regard man as prey, they have been know to strike and bite without releasing any venom at all. We've also got the world's most poisonous spiders in Australia.

With a venom 100 times more lethal than any other snake, the Sea Snake (Hydrophus Belcheri) is the most poisonous. It is the most venomous of any land or sea snake. They are found in the Indian and Pacific oceans.

The Most Lethal Land Snake The land snake with the most lethal poison in the world is the inland taipan. The good news is, these guys only live in the arid deserts of central eastern Australia. Anything or anyone unlucky enough to be bitten by a taipan is injected with some nasty venom. Several Shades of Color Inland taipans are also called fierce snakes and can grow up to 10 feet (2.7 meters) although half of that is the norm. This snake changes color according to season. They range from dark brown to straw colored during the year but at winter they go darker and in the summer they go lighter. Venom Side Effects Taipans hunt mammals so their poison can knock out warm-blooded, fuzzy rodents and animals, including humans. In a single strike (one bite) the venom can quickly paralyze a small animal or wipe out several adult humans. As the poison spreads, the victim will encounter headaches, nausea, vomiting and stomach pains. Sometimes there are convulsions and in extreme cases, coma. Peeing Muscles If that's not bad enough, the poison eats away at muscle tissue. Urine from the victim turns reddish-brown as their muscles deteriorate and pass through the kidneys. Internal bleeding is a major problem from taipan bites. The poison also prevents blood from clotting so the bite continues to bleed. This can cause internal hemorrhaging, especially in the brain. All this sucks for the bite victim but it's great for the snake who only has to wait for its prey to stop convulsing before enjoying dinner. Taipans rarely attack humans, except in self-defense, so as long as they are left alone, humans will be too. http://www.kidzworld.com/site/p1122.htm .

The inland taipan (fierce snake) in Australia is considered the worlds most venemous snake.

This question is really harder than you think, the "most venomous snake" is based upon the toxicity of the snake venom (ie how many people could 1 gram kill) Unfortunately this varies with the snakes heredity, diet, current health, etc. But based on studies it is between: Hook-nosed Sea Snake Russel's Viper Feirce Snake aka Inland Taipan

I've always thought it was the coral snake...but then I looked at the rankings around the net to see I'm way off... (Below is a pic of the Inland Taipan, of Fierce Snake as mentioned above.

The Fierce Snake, also known as the Small Scaled Snake and Inland Taipan is a highly venomous snake that lives in Australia, notorious for having the most potent venom of any species of snake in the world.The Fierce Snake or Inland Taipan is a species of Taipan belonging to the Elapidae family A single bite from the Fierce Snake contains enough venom to kill as many as 100 human adults, or 250,000 mice. The fierce snake's average venom yield is 44 mg, with a 110-mg record yield. It is 750 times more venomous than the Indian Cobra. The Fierce Snake has extremely neurotoxic venom. Although highly dangerous, the Inland Taipan is very shy, and can only be found in Australia. Even so, if it is suspected that a bite is from a fierce snake, Taipan Antivenom should be administered immediately. Also, the victim must be rushed to the nearest hospital in emergency, as taipan venom works quickly. http://en.wikipedia.org/wiki/Fierce_snake

AH YEP AS AN AUSSIE AND READING ON THE NET ABOUT HOW WE HAVE THE MOST VENOMOUS SNAKE IN THE INLAND TAIPAN I DO BELIEVE THIS TO BE TRUE. HOWEVER IT CERTINALY IS NOT THE MOST DANGEROUS. I WATCH A TV SERIES ON ANIMAL PLANET CALLED AUSTIN STEVENS MOST DANGEROUS WHERE HE WENT LOOKING FOR A LANCEHEAD PIT VIPER. WHEN HE FOUND IT IT WAS SUPREMLY AGGRESIVE, REALLY BIG IT ACTUALLY LOOKED LIKE A PYTHON AND IT'S VERY POSINOUS. BUT I HAVE NEVER HEARD ANYONE SAY ANYTHING ABOUT THIS SNAKE. I OVERALL DO BELIEVE THOUGH THAT OVERALL FOR VENOM, AGGRESIVNESS, DANGERNESS, LOCATION TO HUMANS IT WOULD MOST DEFINATLEY HAVE TO BE THE BLACK MAMBA. ALSO IN AFRICA GETTING ANTI VENOM WOULD BE VERY HARD AS IT IS A VERY POOR CONTINENT SO THE BLACK MAMBA WOULD BE MY CHOICE FOR THE OVERALL MOST "DANGEROUS SNAKE"

http://www.avru.org/general/general_fierce.html

Sea snakes and sea kraits. They have to have that potent of a venom to be able to take down fast swimming prey. Their fangs are very short and they are temperamentally docile, in general. They also do not pack the highest volume of venom as the land snakes but, oh boy, is it potent. http://www.explorebiodiversity.com/snakes/main/mostvenomous.html

I've read that the banded sea snake is the most venomous, but it seems like every Discovery Channel show I watch has a slightly different list. Oh, and they live under your sofa.

I had thought it was always the Black Mamba from South Africa but apparently that does not seem to be the case. http://www.manbir-online.com/htm2/snake.27.htm http://www.blueplanetbiomes.org/black_mamba.htm

In the ocean.

Based on many statistics (on the net & books) the absolut winner should be Inland Taipan from Australia.

All I know is that I watched a show on the History Channel (I trust this source over any on the internet)yesterday on poisons, and it said that the sea snake (Hydro...something, probably the same snake the first answer mentioned)was the most poisonous snake in the world. And as the first answer states, it is 100 times more lethal than any land snake.

(1)Sea Snake (Hydrophus Belcheri) is the most poisonos. With a venom 100 times more lethal than any other snake, the Sea Snake (Hydrophus Belcheri) is the most poisonous. It is the most venomous of any land or sea snake. They are found in the Indian and Pacific oceans. Ref answer from Expert Cecelia Ericson ________________________________________ Dr. Steve Austin writes on 2006-07-06 02:55:25 The most venomous snake in the world is hydrophus belcheri, it's a sea snake. One drop of poison from King Cobra can kill upto 160 people in 30 minutes but a hydrophus belcheri's poison can kill more than a 1800 people. IT'S TRUE! (2) Black mamba is a large, streamlined snake with a narrow, coffin-shaped head and smooth scales in 23-25 oblique rows. These active, terrestrial snakes eat birds and small mammals (e.g. rats and dassies). A bite from this snake is extremely serious, and requires large volumes of anti venom (up to 10 ampoules) to counteract the venom. The victim may be fully conscious, but all the muscles are paralyzed; death from respiratory failure usually occurs in 7-15 hours. (3) Trouser Snake Location of trouser snake is throughout the world. Varying from pink to black. Fang-less with a highly venomous spit. Fang-less with a highly venomous spit. Size varies from 3 to 12 inches, depending on its mood & sub-species. This snake attacks mainly women in the lower front abdomen, resultingin an inconspicuous bump. Then a severe swelling followed by excruciating pain after nine months. The attack is not usually fatal. It has been known to attack men in the rear lower abdomen, resulting in an incurable disease and consequent death. (4)The Fierce Snake (Oxyuranus microlepidotus) from Australia has, drop for drop, the most poisonous venom of any snake in the world.Although known as the most venomous land snake in the world is not so as sea snake, there have been no documented human fatalities from the Inland Taipan. All known bites have been treated using antivenom.ans from wikipedia

the western brown snake, i think... how crazy is this? out of the 10 most poisonous snakes, australia has 7!!! including this brown snake!! ahhh run for your life!!;)

Some form of sea snake.

The most poisonous is the Inland Taipan (for land snakes) But the most dangerous and dead;y to humans is the Black Mamba

"Boomslang" Well the strongest venom (in a surface snake) is actually found in a African snake called the Boomslang. It has the most concentrated venom of any snake in the world! However since they are tree dwellers and have fangs that are located near the back of the mouth...they don't get much attention, nor many human kills!!!

IN AUSSIE THE MOST TOXIC SNAKE IS THE INLAND TAIPAN(FIERCE SNAKE)BUT THE MOST DEADLIEST WOULD HAVE TO BE THE COMMON EASTERN BROWN AS THIS SNAKE IS THE SECOND MOST TOXIC SNAKE IN AUSSIE (EVEN THOUGH THE COASTAL TAIPAN COMES IN SECOND THIS IS BECAUSE VENOM IS NOT ONLY RATED FOR ITS TOXICITY BUT FOR THE OTHER ENZYMES THAT CONSIST IN IT SO THE TAIPANS ARE KNOWN TO HAVE A MUCH BIGGER YIELD(AMOUNT)AND THE SPREADING FACTOR IS HIGHER IN ITS VENOM_BUT ON TOXICITY ALONE THE EB COMES IN SECOND) ANYWAY THE REASON I RATE THIS SNAKE AS AUSTRALIAS MOST DEADLIEST IS BECAUSE IT IS SO COMMON AND SO OFTEN FOUND AROUND HUMANS ITS INTERACTION EITHER BEEN FOUND IN A HOUSE OR AT SCHOOL OR IN HAY SHEDS IS ALOT MORE COMMON THEN COASTAL TAIPANS AND THE INLAND IS NOT A THREAT TO HUMANS AT ALL BECAUSE OF WHERE IT IS LOCATED NOT MANY PEOPLE LIVE WHERE THAT SNAKE IS...WORLD WIDE WELL DEPENDS ON WHERE YOU LIVE.. YOU CANT SAY THE BLACK MAMBA IS WORLD WIDE BECAUSE ITS NOT FOUND WORLD WIDE BUT NO DOUBT WHERE IT IS FOUND IT CAN CLAIM THAT NAME OF BEING THE DEADLIEST AND SO ON FOR EACH SPECIES..BUT IF YOU QUOTE THE MOST TOXIC SNAKE THAT WAS TO BE FOUND ON LAND WORLD WIDE THE AUSSIES GET IT WITH THE INLAND TAIPAN...RBB

The answer depends on whom you believe. Austin Stevens claims that the Boomslang of Southern Africa is the most venomous, the late Steve Irwin names the Inland Taipan or Fierce snake from the desert regions in Australia, and I think Jeff Corwin lists the Faint Banded Seasnake as the top poison of the herpetological world. Of the three named here, the Boomslang would be the most dangerous simply because of the chances for actual contact with humans. A for the most dangerous snake in the world, most experts give that honor to the Black Mamba, but Australia's King Brown is potentially as dangerous and the Fer De Lance or lance headed viper of central and south america is certainly a top contender as well(although I tend to think that the mamba is probably the most aggressive venomous snake commonly in contact with humans)

The inland taipan,australia

the golden dart frog has the most toxic venom in the world.(can kill more than 100 humans.....i dont know exactly)

Oxyuranus temporalis This is perhaps one of the most venomous known snake species. Its two closest relatives, the inland taipan (or fierce snake) and the coastal taipan, are ranked first and third most venomous snakes in the world, respectively. The discovery of the new species (known only from a single specimen) highlights how little is known of even relatively large animals in harsh, poorly collected habitats (in this case an isolated arid region of Australia). It also emphasizes the need for accurate taxonomy of venomous species for proper treatment of bites.

The Black Mamba of Africa. Two drops of its venom can kill a grown man within ten minutes. Yes! I said ten minutes.

Keep in mind that "most venomous" is very different from "most dangerous". Many Australian snakes (like the taipans) have extremely potent venoms, but Australia averages LESS THAN ONE human fatality from snake bite per year. Compare that with 5-10 deaths per year in the US from the far less venomous rattlesnakes. Russell's Viper of southeast Asia kills more people than any other snake. They are slow and rely on camouflage for protection. When they see a large animal approaching they remain still. Get too close and they'll bite. They live in rice fields where plants are often so close together that people can't see where they're walking.

The Fierce Snake is the most toxic, but is shy and lives in sparsely populated areas. The Black Mamba and the Coastal Taipan are both highly toxic and very aggressive ... however, given the Coastal Taipan's habit of giving up to six bites in a couple of seconds, I'd put my money on him. The Eastern Brown Snake od Australia, while it's venom is not quite so toxic, has very toxic venom of a very high yield and it has a particularly irritable disposition, and is responsible for more deaths in Australia than any other snake. It is also common in populated areas. The Russell's Viper and the Common Cobra, while nowhere near as venomous or aggressive as these snakes, kill many more people annually because they live in more densely populated areas, in countries where poverty makes access to anti-venene treatment less accessible. Hope this helps.

The world's most venomous snake is not Hydrophis belcheri (beaked sea snake) but Oxyuranus microlepidotus (Inland Taipan or Fierce snake). Hydrophis has an LD50 count of 0.164 while Oxyuranus has a count of 0.025 which is far more venomous. Check out the link; http://www.avru.org/general/general_mostvenom.html

It is the fierce snake in Australia. According to Animal Planet, it only takes 1/14,000 oz. of their venom to kill a human.

The Inland Taipan (Oxyuranus microlepidotus, Small Scaled Snake, Fierce Snake) is native to Australia and is the most venomous land snake.[1][2] It is a species of Taipan belonging to the Elapidae family. Although highly venomous, it is timid and docile, providing it is left alone.

The Mother In Law Snake

the black mamba is rated the deadliest snake in the world which means nothing to the rating of the worlds most venomous.. Australia has the top ten most venomous snakes in the world, fierce snake at number 1 The black mamba is classed as the most deadliest because it is the fasted and one of the most tempered snakes in the world, causing more deaths then any other animal in africa, fortuantly for Australians the fierce snake is found no where near humans, living in the rugged deserts of Australia... with one single bite having enough venom to kill 100 adult humans it is rated by far the most venomous snake in the world! if you were unlucky and happend to be bitten by this snake you would be dead within 20mins depending on your size, and chance of making it to hospital from its habbitat is absolutely no chance!
