Is the daddy longlegs spider the most poisonous animal on Earth, but can't bite us, because its mouth is too small?

No one actually knows, if the daddy longlegs spider is the most poisonous animal in the world. The way we would find out is by milking it, and then injecting the poison into a human. It probably isn't the most venomous animal in the world, because the poison dart frog, and box jelly fish are very poisonous, and it would be hard to beat them.- John Baskin
