World’s Most Poisonous Snake Ever - World's Most Venomous Snake – and Most Fierce Snake in the World

Updated on January 25, 2014

1. Faint - Banded Sea Snake - Hydrophis Belcheri - World’s Most Poisonous Snake

The Faint - Banded Sea snake, also known as Hydrophis belcheri or Belcher's Sea Snake, is the world’s most poisonous/venomous snake. By the way, we say ‘snakes are venomous’ and not ‘snakes are poisonous’. Hydrophis belcheri snakes lives in water of Indian Ocean especially in Philippines: Visayan area, Panay; New Guinea, Gulf of Thailand, Australia, Solomon Islands, and Ashmore Reef in the Timor Sea. When fully provoked, Hydrophis belcheri will spite venom enough to kill 10,000 people. Fortunately, Hydrophis belcheri is a very docile which will hardly bite you – you need to provoke it severally for it to unleash the deadly bite that will kill you in only a few minutes. The Hydrophis belcheri is a snake that spends most of its time in water. This snake is a good swimmer with a paddle-like tail like all other sea snakes. This snake will grow to be 3 feet in length and will usually have a thin body which is chrome yellowish in color and with dark greenish bands.

Libby101a had this to say about Hydrophis belcheri snake: “Hydrophis Belcheri is 100 times more venomous than the Inland Taipan. Only a couple of mg of this snake's myotoxic venom is plenty enough to kill an estimate of more than a thousand people. If this snake injects its venom, death will follow within a few minutes. It is the most toxic venomous snake known to date and holds the record in the Guinness Book of Worlds Records. Most people are behind on current research! The internet is behind as well! Very few places list accurate information on the most toxic species of snake in the world!”

2. The Inland Taipan

The snake called Inland Taipan is the 2nd world’s most poisonous snake. The Inland Taipan is also known as the Fierce Snake because it is a veryt fierce snake in the world. Inland Taipan is commonly found in Australia. Fortunately, this snake is very shy preferring to avoid trouble as much as it is possible. However, when provoked, Inland Taipan will bite with enough venom to kill 100 people. Inland Taipan’s venom is 400 times more toxic than venom from a rattlesnake and 50 times more toxic than venom from cobra. Its neurotoxin venom will see you dead in 40 minutes if you do not seek medical treatment. Treatment is usually by anti-venom.

The Inland Taipan is the 2nd world’s most poisonous snake/most venomous snake. The Inland Taipan has an averages length of 6 ft and can grow as long as 8.5ft. The Inland Taipan is to be found mostly in the southeast part of the Northern Territory into west Queensland of central Australia. The Inland Taipan is dark tan in colour, and colour will usually change depending on the season from dark hue to brownish olive-green.

      I just want to correct some misinformation posted earlier. LD50 is not the does required to kill 50 mice. It's the dose that will kill 50% of all the mice that receive that dose.

      LD50 is used in research because that's the tipping point. Up to that point, the victim is statistically more likely to be survive, although it may be only 1% more likely. At LD50 dosage, the victim is equally likely to survive or to die. It's 50/50. Beyond LD50, the odds get progressively worse for the victim.

      The correct list is as follows:

      1- Belcher Sea Snake LD50=0.0001

      2- Inland Taipan LD50=0.010

      3-Beaked Sea Snake LD50=0.03

      4-Costal Taipan LD50=0.06

      5-Tiger Snake LD50=0.12

      6-Coral Snake LD50=0.18

      7-Malayan Blue Krait LD50=0.24

      8-Saw Scaled Viper (Carpet Viper) LD50=0.32

      Snakes are not poisonous, they are venomous! The distinction is really quite pertinent.

      Really great hub. I heard the Philippines cobra was the most deadly in the world. It hangs out in the luzon region though, not the Visayans and is somewhat known for living on rice farms and biting farmers. Death comes super quick. Scarey creatures for sure.

      I am afraid of any snake, big or small, venomous or not. Good to know that the most venomous snake Hydrophis belcheri snake lives in the water. I will be extra careful whenever I go for a swim in the sea.

      voted up and tweeted, so that the rest of the world are informed !

      I'd hate to be bitten by the Banded Sea Snake and be responsible for the deaths of 9,999 other innocent people! Of course, I would be dead too, but, still.

      Maybe, out of the other 9,999 people, they wouldn't all be innocent.

      Great hub!

      The taipan is the most venomous land snake in the world, although a successful anti-venom has been developed. But with almost all of these snakes, the only way to be bitten is if you provoke, step, or sit on them!!

      I love this kind of information. I was wondering just how poisonous they are? The most poisonous Taipan, is it the volume of the poison or the qualities of the poison? It sounds like both. Rattlesnakes are dangerous little buggers, but I sure don't want to meet that Taipan. If you are injected with enough venom to kill 100 people, what are your chances of survival? I never even heard of it before. Thanks for the interesting information.
