No, daddy long leg Spiders don't even make the top ten list of most poisonous animals.
Most poisonous is a difficult thing to define actually. It can mean several things: most toxic, most venom produced, perhaps even the highest death count can determine what is most poisonous.
Here's a top ten list of most poisonous animals and what lands them on the list:
- Box Jelly Fish - There have been 5,567 recorded deaths due to box jelly fish stings since 1954. Box jelly toxins is a blood, blister, and neuro-toxin, and there is no known antidote. The only treatment is washing with vinegar within minutes of being stung.
- King Cobra - Ophiophagus hannah is capable of injecting five times more venom than any other venomous snake. (Highest volume venom production)
- Marble Cone Snail - Perhpas the single most venomous animal on the planet, a single milligram of marble cone venom is powerful enough to kill 20 adult humans. There have been only about 30 reported deaths due to marble cone poisoning though.
- Blue-Ringed Octopus - blue-ringed octopus venom is similar to that of the marble cone snail, with similar properties.
- Death-Stalker Scorpion - venom from the death-stalker, while deadly, is not likely to kill a healthy adult human. It does however cause systemic wide pain, coma, seizures, and in children and those with other conditions death.
- Stonefish - stonefish are commonly believed to be the most venous fish. No know anti-venom exists for stonefish stings, and the pain it causes is considered to be the worst known pain.
- Brazilian Wandering Spider - the Brazilian wandering spider or banana spider was identified in 2007 as having the most potent venom of all spiders. While it is not likely to kill a human, it causes intense pain, tissue death, and priapism.
