Are grandaddy long leg spiders the most poisonous spiders in the world?
No, actually the most poisonous spider in the world is the Amaxonyan Rectilae, found in the jungle of the border of Colombia, Peru and Brazil. Like The Brown Recluse Spider, which is another one of the most poisonous spiders, the venom danger is primarily in tissue damage. Its poison kills the cells and tissue at the bite plus cut down all the nervous system. One bite of this kind of spider is capable of killing an adult elephant in just 15 seconds.
