What Is The World's Most Poisonous Thing?

          There are several things in the nature which are very poisonous. These poisons are mostly used for defence against predators. When predators attack the poisonous animals or plants, it triggers the natural defence mechanism in these poisonous animals. The poison is released by them and the attacking predator is subjected to die eventually.

          The most poisonous spider is the Black Widow Spider. The world's most poisonous plant is the castor bean plant. Castor bean contains ricin. Ricin is poison which stops the protein making process of the plant. These plants are very common. The most poisonous creature is the golden poison frog. They are highly toxic as they cause paralysis in the victim which ultimately results in death. The most poisonous snakes are Cobras and Vipers. The poison attacks the nerve cells in the victim and causes nervous breakdown ultimately resulting in death.

First of all you're all wrong!!! The box jelly fish is the most toxic thing to human. If we are talking plants its a plant in northern michigan and northern wisconsin, i cant remember the name but if you make skin contact with it and the oils it secrete get on you and you go in the sun your skin get a deadly reaction to the oils and begins to basically die. And the most toxic spider is the wandering spider( not the funnel web or the black widow!!!.)  The Colombian dart frog by the way isn't even that toxic in comparison to most other dart frogs and deep rainforest snakes. The only correct statement you people made was the inland taipan of Australia. So research before you make a statement like that!!!!!
