Hi,I was asked at work today which animal has the most toxic venom towards humans.I wasn't to sure but I said it would most probably be a marine dwelling animal/fish,and at a geuss mentioned the Cone snails,The fish hunters,one in particular the Conus geographus.The question has been bugging me all day and I'm hoping somebody can enlighten me on this question.I know I've directed the question to BGF,but please feel free to add your point of veiw.Thanks

Hi,
I recall hearing from many different sources that the box jelly fish is the single most toxic animal on the planet. However, I belive I remember BGF mentioning that he belives scorpions will prove to have the most toxic venom, drop for drop. Many venomous animals have yet to have their venom studied so its going to be very interesting to see how the list change as time moves on.
Regarding the most venomous animal to a human, I have no doubt that snakes will always lead that catogorey. Though it may not be from venom potentancy, the sheer quanity is unmatched and nothing to my knowledge can hang with a snake's venom yeild(could be wrong though).
Well, I hope this helps. Looking foward to what BGF, WW and Roger H have to say about it.
All the best,
Jeremy

I do believe your right,I just saw it on the tube last night and it was said to be the CONE SNAIL as having the most toxic venom with a makeup of over 40 different protiens. Jeff Quarles Va

I'm not real sure but I know that Phyllobates terribilis (Golden Poison Frog) found in a small part of Colombia, has one of the most toxic poisons to man. "at least under certain circumstances, a wild Collected Golden Poison Frog could cause a human death on CONTACT."
Walls Jerry G. Poison Frogs:Jewels of the Rainforest of the family Dendrobatidae, T.F.H.;1994 : p253-255
They have Batrachotoxins that cause human death when passed though the skin. Hope this helps. The other posts may be more helpful as I don't know much about aquatics.
Good luck,
T.C.

I believe that it is the box jellyfish that is the most toxic of the lot. It has known to cause fatalities in less than 3-4 minutes. Although the venom of the cone snail is highly complex in its makeup, it comes in a close second to the box jelly.

I always thought that the deadliest venom known to man was that which is found on the edge of the tongue of the North American housewife!
Just a little humor as you guys search for the more serious answer.

I seem to recal reading that the most venomous *thing*--speaking strictly in terms of toxicity--would be a jellyfish or a snail or some other invertebrate. I believe that this is based on the fact that their toxins are of a smaller molecular weight, which means that they can squeeze more toxins into the same droplet of venom. (At least more toxins in the same ammount of tested venom.)
Cheers
Roger

i read in a national geographic magazine and several websites that the golf ball sized blue ringed octopus had the deadliest venom to humans, but upon reserch on another website, i came across this:TTX is found not only in blue-rings and many fishes in the family Tetraodontidae (hence the name tetrodotoxin), but also in several other groups of animals including California newts (genus Taricha), central American harlequin frogs (genus Atelopus), as well as a scattering of invertebrates including a South American tunicate (sea squirt), a sea star, several snails, some xanthid crabs, a horseshoe crab, two ribbon worms, some arrow worms, and a flatworm. It was a mystery why such a diversity of unrelated organisms would all evolve the same toxin, until it was recently discovered that bacteria associated with many of these animals actually produce TTX. This is the case in blue-ringed octopuses. Their salivary glands harbor dense colonies of TTX-producing bacteria. The blue-rings have evolved a symbiotic relationship with the bacteria, providing them ideal living conditions while using the toxin they produce to subdue prey and as part of their highly advertised defense.
