you see you should correct nr. 3 too - 0,12 instead of 0,155

Difficult to believe these values, Peter.
Naja nivea IV nearly 0,6 and Naja naja 0,3?
Just one example.

BTW - I just read Your answer. Mr M. is no longer visible for me - thanks to the foo list.

a Dra Maria de Fatima, do Inst. Butantan, utilizou o SORO ANTI-ELAPIDICO, produzido no próprio Butantan e todos los rotones não sobreviveram...

O veneno de M.surinamensis é muito diferente das outras Micrurus.... é claro elas se alimentam de peixes como você mesmo comentou no forum....

Se o cara foi envenenado, acho que não deve ter muitas horas de vida!!!!

This is a note sent to me 5/22/2011 from a colleauge at Butantan in Sao Paulo Brazil explaining that in their studies on aquatic Elapids , that theyre venom is quite different than other Elapids and may be due to their diet.

*it fore tells that even with SORO ANTI ELAPIDICO your chances to survive a bite from Micrurus surinamensis are slim.

Guenter good observation , Micrurus surinamensis LD50 > Naja Nivea.

Peter , thanks for perfecting my statement.

*examples 1, 2, 3, seem to be > than The Faint Banded Sea Snake, Hydrophis Belcheri.

a) Request correction advice , Peter Zurcher for Intramuscular LD 50 score of Five SeaSnakes.

Number 3) is in fact : The Reef Snake, Hydrophis Ornatus LD50 0.12

b) Edit foo list, on behalf of Guenter Leitenbauer.

Delete values and assign new values on * examples 1,2,3, seem to be > than The Faint- Band SeaSnake, Hydrophis Belcheri.

Edit: The Black banded Sea Snake , Hydrophis melanosoma, The Olive SeaSnake, Aipysurus laevi and The Reef SeaSnake, Hydrophis ornatus, seem to have a greater LD 50 score than The Faint Banded Seasnake, Hydrophis belcheri.

c) Edit foo list , on behalf of Guenten Leitenbauer and assign new key values.

1) From, Example: Micrurus surinamensis > Naja nivea

b) To: Micrurus surinamensis seems to have an greater value of LD50 than even Naja Nivea.

Note : You guy's are tough professors.

Why is this hard to believe?

Wolfgang I always thought that Naja nivea is one of the cobras with the most potent venom besides Naja philippinensis. Am I wrong?

Naja nivea, LD score, 0.57

Naja naja, LD score, 0.35 addtl. side note, Careful - any Asiatic cobra may have been referred to as N. naja in the past.

Some people write clever!
Some others do never!
Just copy and paste
And I call this "waste"!

(of time, energy and reputation, well the latter seems to be around zero right now)

Perhaps, not many of you realize that these statements and the intramuscular LD50 score
pertains to, THE MOST TOXIC VENOMOUS SNAKE ON EARTH, The Fainted-Banded Sea
Snake, Hydrophis belcheri.

Thank you, goes out to your partcipation and comments , Professors
Wolfgang Wuster, and Peter Zurcher.

And as always the lively participation of Guenter Leitenbauer.

Mister Albert "LD50" Montejo,

are you just regarding those LD50-tables in a somewhat naive manner or are you trying to create confusion conciously?

Pleas note, that
- the "most toxic "snake on earth" according to the intramuscular list of the Venomdoc-site is not Hydrophis belcheri, but Hydrophis melanosoma.

- LD 50 value for Oxyuranus microlepidotus is not given in the intramuscular list.

- LD 50 value for Oxyuranus microlepidotus is given in the subcutaneous list (0,025) whereas Hydrophis melanosoma is listed with a value of 0,111. Value of Hydrophis belcheri is not given in the subcutaneous list.

- not too great importance should be attached to these values, when it comes to envenomations of human beeings.

Further on, i'd like to ask you not to elevate my person to the same level as WW (even it might be complimentary to me), i'm wether a professor nor a scientist.

Sincerely

Peter Zürcher

Once again, excellent coverage on the age old question of which is THE MOST TOXIC SNAKE ON EARTH .

Peter , i get asked this question daily by all types of people, i was researching and wanted a second oppinion on venomdoc's list, as all other non referenced documents points to Hydrophis Belcheri .

Still the anwser lies somewhere in between these two statements.

a)- the most toxic "snake on earth" according to the intramuscular list of the Venomdoc-site is not Hydrophis belcheri, but Hydrophis melanosoma.

b) LD 50 value for Oxyuranus microlepidotus is given in the subcutaneous list (0,025) whereas Hydrophis melanosoma is listed with a value of 0,111. Value of Hydrophis belcheri is not given in the subcutaneous list.

2) Could it be that the actual MOST TOXIC SNAKE ON EARTH is Oxyuranus microlepidotus.

on EARTH , or EARTH ?

By the way: Please tell me how many bites occur from the most toxic snake on earth and how many die?

regards Fabian

Thank you, for your participation Fabian , my only interest is the LD50 list in and of it self not how dangerous any activity is.

Their are reasons why LD50 lists are created , ill be careful with my vocabulary to not stifle your thoughts, i am not able to determine which is THE MOST TOXIC VENOMOUS SNAKE ON/OR EARTH.

Fabian Dirks of Germany can you anwser the question with one definitive specie all methods digested and numerically brought forward, of which is THE MOST VENOMOUS SNAKE ON/OR EARTH.

Regards,

Albert.

Fabian is this your question , on Venomous Reptile Org.

OK, LD-50 TEACHER NEEDED !!!! Reply
by Fabian on September 29, 2003 Mail this to a friend!

I STILL NEED HELP WITH THIS LD-50 CHART. HERE IS THE THING, I FOUND THE TIGER RATTLESNAKE AT 0.056, THEN I FOUND THE FOREST COBRA AT 0.289 . IT SEEMS THE TIGER TAKES LESS VENOM TO KILL THEN THE FOREST. PLEASE HELP ME GET THIS DOWN.
THANKS, FABIAN

By the way - how high is the LF50 for forum members?
(Number of tedious postings from a member until 50% of the other members Leave the Forum)

Just out of curiosity, and this is along the lines of Fabian's question, how many people, each year, on average, are bitten by a sea snake, and how many die?

April, good question i dont know, the interest is the purely biochemical components of venom my second interest after collecting and breeding venomous and non venomous reptiles.

im not trying to put fear in any ones heart , if you get scared by my statements than your in the wrong business , you and i grew up differently in the herpetological scenario .

If this question that im asking on purely statistical reasons, can not be anwsered then let's let this thread die on that note.

addtl. i leave this LD50 chart here to any one who can figure it out and anwser .
Which is THE ONE MOST TOXIC SNAKE ON/OR EARTH.

Fabian Dirks wrote:: Yes I am scared to go swimming now...

Hydrophis swimmingpoolii, the Swimming Pool Sea Snake lives in chlorine swimming pools. No antivenin for this rare species, which has caused a number of fatalities each year.

LD50 is 0.04

LOL , i get it April ....well what can you say.

In the publication(entitled): 'Sea Snakes' by Harold Heatwole(1999. Australian Natural History Series. ISBN #: 0 86840 776 3), Table 10.1 (on pp: 115, entitled: Attributes of some sea snakes in relation to their danger to humans) shows a list of sea snake species with a Mean Toxicity(LD50 mice; mg/kg). At the top of the list is Acalyptophis peronii with a LD50 of 0.08 and Aipysurus duboisii with a LD50 of 0.04 Heatwole states(on pp: 117)that: 'There is a wide range of toxicities of venom among sea snakes with a difference between weakest to most powerful of over 500 fold. The species with the most toxic venom(for mice) are Acalyptophis peronii and Aipysurus duboisii with LD50s of less then 0.1 mg/kg(Table 10.1)'. I hope that this is helpful to the discussion.
