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!”

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.

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

nickanator123 on February 06, 2012:

PADDYBOY60 from Centreville Michigan on October 08, 2011:

Thank you for sharing this info. I knew a lot of this, but I know that a lot of people don't.

funmontrealgirl from Montreal on September 28, 2011:

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.

syedhassan from pakistan on September 28, 2011:

waoooo great info

henrygogoals from Singapare on September 27, 2011:

Snake make me feel not comfortable. Thanks for sharing.

goldenfire80 on September 26, 2011:

I thought the politicians where the most dangerous

Ingenira on September 26, 2011:

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 !

mikeyyb17 on September 25, 2011:

great detail it seems like you've done your research. The only snakes i could have thought of was the king cobra, or the black mamba

GlstngRosePetals from Wouldn't You Like To Know on September 25, 2011:

Great article and very informative. I have a similar article for venomous creatures in Arizona that you might like to see. Again great article thank you!!

susan beck from drexel hill,pa on September 11, 2011:

Actually, the deadliest snake in existence can only be found in Pennsylvania. I'd like to give you the exact location, but I don't know my ex-husband's address!

Cashbackshopper on September 05, 2011:

I use to think Black Mamba is most poisonous snake, thanks for sharing this info.

m4rkb3rt on March 20, 2011:

These is very fascinating information - from afar! Thanks

Emma from Houston TX on March 11, 2011:

Interesting article that almost frightened me with those colorful pics of dangerous snakes.

Monitorman on March 02, 2011:

Australia has all the nasty ones :)

jimcrowthers from Port Charlotte on February 05, 2011:

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!

Mark from IL on January 08, 2011:

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!!

Hello, hello, from London, UK on December 28, 2010:

Thank you for your great research and information. The very sight would make break all speed records.

SteveoMc from Pacific NorthWest on December 27, 2010:

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.

greatpyr123 on December 26, 2010:

Interesting! I've never even heard of some of these species.
