Depends to some extent on whom you talk to, but it would appear that a jellyfish common to warm waters of the South Pacific called the Box Jelly or a relative, the Sea Wasp are the deadliest. (There's a spider in Australia that I wouldn't want to run afoul of. The male Funnel-Web Spider can inject a venom that, if left untreated, can kill in a few hours. Even if successfully treated, recovery often takes several days -- sometimes weeks.) wrong!!!!! The most poisonous animal in the world is a type of tree frog known as the poison arrow frog The dictionary definition of venom: "The poisonous fluid that some animals, as certain snakes and Spiders, synthesize and introduce into the bodies of their victims by biting, stinging, etc." The question didn't ask for the most poisonous creature in the world... it asked for the most venomous. The Poison arrow frog secretes a highly poisonous fluid from its skin. It neither bites nor stings, and it doesn't inject its secretions. It's toxic -- not venomous. However, I admit that is, to some extent, splitting hairs. However, I doubt if its secretions are more toxic than the venom of either the box jelly (Chironex fleckeri) or sea wasp (Chiropsalmus quadrigatus). The amounts they inject are extremely small, but they can kill very very quickly and very painfully. Nevertheless, if you want to delve into poisons I think you'll find that the most poisonous creature is the bacterium known as Clostridium botulinum... Its secretion - the botulism toxin - is so powerful that a single ounce of the purified crystal would kill every human on the face of the earth.

Which spider is the most poisonous in the world?

The Sydney Funnel web spider is the most poisonous spider on earth, causes comas, seizures and death within the hour of the bite. Those who believe the wandering spider (or more officially, the banana spider) is the most venomous are incorrect and it is only reported the most dangerous because there are more reported bites, but it is not as venomous.The above statement is actually incorrect. The Brazilian Wandering spider's venom is far more potent then that of a Sydney Funnel-Web. It hosts a neurotoxin that is near-identical to the one of a King Cobra and can cause paralysis in a matter of minutes. Death in roughly an hour.The most defining difference in deadliness between the two spiders is the fact that there is a cure for the Sydney Funnel-Web spider's venom. While the is but only a treatment for the bite of a Brazilian Wandering spider. The Brazilian Wandering spider's venom can kill just as quickly as a Sydney Funnel-Web spider's venom can, but can also cause permanent damages.

Is a black and white jumping spider poisonous?

Although all Spiders have venom, few of them have venom potent enough to seriously hurt a human. It's also uncommon for a spider to bite a human. They need to be provoked which is usually caused by accidentally pressing against them, sitting on them, or rolling over on to them in bed. I have handled hundreds of jumping spiders and I have never been bitten. Most are small and can not open their fangs wide enough to bite into skin.

Do banana spiders eat bananas?

No, spiders cannot even eat them! They cannot chew food. When they get to the bug in their web, they bite it and inject venom. The venom either paralyzes or kills the bug. Then the venom turns the bug's insides into liquid. Then, the spider will most likely drink the liquid.
