There are many very venemous snakes in the world. It is difficult for researchers to say which is the most deadly because there are many variables to a snake bite that can determine how quickly the venom will take effect. Obviously, if a person was bitten in an artery, the poison would circulate through the body much quicker than it would if a person was bitten in a toe. One of the quickest death by snake bites I have ever heard of, however, was a bite from a black mamba. If I remember correctly, that person was bitten and died 2 1/2 minutes later.

The Taipan, or "Fierce Snake" is the most venomous snake in the world. It resides in Australia.

Black Mamba--deadliest.

The fer de lance is pretty bad.

The most venomous snakes are a few in Australia, including the Fierce Snake and Inland Taipan. None of the Australian snakes are implicated in many fatalities, however. They live where there are few people, and are not prone to bite. In Australia, there have been only 2 fatalities in the past 20 years, other than in people who were deliberately handling snakes! The snake which most often causes human death is Russell's Viper of South Asia. It is slow and sits still when a large animal (like a human) approaches. Most people get bitten when they step on or near one.

There are two families of snakes which are always venomous, the Elapids and the Vipers. The Elapids have, in general, more potent venom, but, most are either small or fast; they do not cause as many human fatalities as the Vipers. They are mostly nonaggressive, and most (like cobras) flee at the sight of a large animal. Sea Snakes have the most toxic venom, but are extremely docile; they virtually never bite, even if handled. Vipers (like rattlesnakes) have less potent venom, but cause a lot more human fatalities. They are slow and fat and stand their ground when a large animal approaches. The one which causes the most human deaths is Russell's Viper of Southeast Asia.

the most venomous is the inland taipan in australia the most deadly is the black mamba in south africa

The Inland Taipan Or Fierce Snake - Oxyuranus Microlepidotus- is the world's most venomous snake. Of the Top 10 most venomous snakes, all are Australian 1.Inland Taipan Or Fierce Snake - Oxyuranus Microlepidotus 2.King Brown Snake - Pseudechis Australis 3.Taipan - Oxyuranus Scutellatus 4&5 Mainland & Eastern Tiger Snake 6. Sea Kraits - Laticauda Colubrina 7.Tiger Snake - Notechis Scutatus 8.Black Tiger Snake - Notechis Ater 9. Death Adder - Acanthophis Antarcticus 10.Western Brown Snake - Pseudonaja Nuchalis http://snake.fol.nl/Page2.html Fortunately MOST of these are desert or marine snakes, and rarely encountered, but the brown snake is found near metropolitan sydney and has taken a few lives in the last few months (probably due to the drought, they have had to get closer to housing). According to a website I found, the most aggressive snakes are (fortunately)not necessarily the most venomous. www.bugsinthenews.com/Texas%20Snake%20Web/snake_encounter_reports_2004.htm Exceptions to this include the cottonmouth moccasin the most aggressive, followed by the rattlesnake, then the copperhead and the coral snake not to forget the Black Mamba of Africa (responsible for many deaths each year) and the king cobra.

Boa constrictor?

I HAVE A PRETTY GOOD ARGUMENT AS TO WHY AUSTRALIA DOESNT HAVE MANY SNAKE DEATHS. ITS BECAUSE MOST AUSTRALIANS LIVE ON THE COAST AND THE SNAKES LIVE IN THE OUTBACK. ONLY A FEW SNAKES ACTUALLY LIVE IN AREAS WHERE HUMANS ARE EG COMMON BROWN, TIGER SNAKE AND COASTAL TAIPAN. IN THE US PEOPLE LIVE ANYWHERE AND EVERYWHERE AND SO THE DISTRIBUTION IS FAR GREATER. THEN YOU LOOK AT ASIA. OF COURSE THEY ARE GOING TO HAVE THE MOST DEATHS. HALF THE WORLD LIVES THERE AND ALMOST 20% LIVE IN ONE COUNTRY LIKE INDIA. IMAGINE IF THE FIERCE SNAKE AND TAIPAN LIVE IN ASIA AND THOSE VIPERS LIVED IN AUSTRALIA. THEN I THINK WE WOULD BE TALKING DIFFERENTLY. BUT AS I HAVE ALRESY STATED THE OVERALL MOST DANGEROUS IS THE BLACK MAMBA.

The black mamba is by far the deadliest but you have to consider when and where you are bitten. King Cobras can deliver as much as 2 tsp. of vemon in one bite (they grow to about 18 ft. in length). The Fierce snake is also very deadly but not very aggressive. the most fatalities occur from the Russels viper because they live where humans are in constant contact with them and there is no medical facility close by in sputhern Asia. The other factor is how quickly you can get to an anti-venom. If you were bitten by a rattlesnake and you couldn't get treatment right away, they will kill you as well. Any venomous snake will kill you. You just have to know your snakes and knwo what to stay away from.

AUSTRALIA OWNS THE MOST VENOMOUS LAND SNAKE KNOWN TO MANKIND IT IS THE INLAND TAIPAN(OXYURANUS MICROLEPIDOTUS)..THIS DOES NOT MEAN IT IS THE MOST DEADLIEST.. DEADLIEST TO HUMANS MEANS WHAT SNAKE INTERACTS IN A HUMANS LIFESTYLE ALOT ....IN AUSTRALIA THE MOST DEADLIEST LAND SNAKE WOULD HAVE TO BE THE COMMON EASTERN BROWN SNAKE (PSEUDONAJA TEXTILIS TEXTILIS)COMMING IN SECOND WOULD HAVE TO BE THE COASTAL TAIPAN(GENUS OXYURANUS)AND THEN THE TIGER SNAKE FAMILIES ,THE BLACK SNAKE FAMILIES (INCLUDING THE NOTORIUS "KING BROWN" WHICH IS ACTUALLY THE MULGA SNAKE AND IS A BLACK SNAKE)FOLLOWING THE OTHER BROWN SNAKE FAMILIES...AS I SAID MOST PEOPLE IN AUSTRALIA ENCOUNTER THE COMMON EASTERN BROWN SNAKE SO AS THIS IS STATED IT WOULD BE AUSTRALIA'S MOST DEADLIEST SNAKE..IN THE WORLD I CANT ANSWER THAT ..REDBELLYBITE.

Venom is measured on the LD50 scale. As the other poster answered the green sea snake and the inland taipan range between 0.01 and 0.03 mg/kg and are near the top of the LD50 test. the russell's viper, which can be quite agressive, probably kills more people than any other snake. the black mamba is deadly and agreesive. and all of them are nothing compared to what can be found in a bulging can of peas - botulism - which is by far the most toxic substance at 0.0000003 mg of botulin/kg.

The Taipan has the deadliest venom, but human bites are rare. Australia is where you'll find most of the top venomous snakes in the world but usually less that 5 fatalities per year. The US usually has more each year than Australia. The Aussies are smart enough not to mess with them, most American bites happen trying to catch them. Snake bite records are far from accurate because many arent reported. The most on record come from the Indian Cobra. Between 5-7000 per year is the average. Cobras are hard to piss off(usually) but if you do piss one off there are several sub-species that will chase you. The biggest misconception when it comes to venomous snakes in the wild is a toss up between thinking the snake is dead, and that a young small snake is less dangerous than a large adult. Envenomation is voluntary, the snake controls if and how much venom it releases. Adult snakes use venom for food, they dont waste it and usually its a dry bite. Younger snakes have less controll and usually inject as much as they can.

hydrophis belcheri is much more venomous than Inland Taipan source:- http://kalyan-city.blogspot.com/2008/07/worlds-top-10-most-poisonous-venomous.html

Australia averages one snakebite death every 5 years. All of their venomous snakes are elapids. Elapid snakes (the family which includes cobras, sea snakes, taipans, and coral snakes) have the most potent venoms, but bite and kill many fewer people than vipers (rattlesnakes and their relatives). Most elapids are either too small to effectively bite a human (their fangs are far shorter than those of vipers), or are docile, or have the tendency to flee when disturbed. For instance, the eastern (US) coral snake has much more potent venom than any other US snake, but I have never heard of one killing a person. Vipers are fat and slow and tend to rely on cryptic coloration for protection. They sit still when they see a big animal approaching, resulting in many more encounters with people. They have long fangs and are much more likely to deliver a large amount of venom. Everywhere in the world where both vipers and elapids occur, the vipers are involved in many more bites and many more human fatalities. In India, a country with many species of cobras (elapids) the vast majority of human deaths are due to Russell's Viper, the snake which causes the most human fatalities worldwide.
