Poisonous Sting
Venomous arachnids are the group of arthropods most feared by people. Even if a bite
may be fatal to another animal, it is unlikely that it will be fatal to a human being, who
would be attacked only as a means of defense in cases of fear or danger. The scorpion
stands out among the most dangerous species. It uses its stinger when it wants to be certain
of catching a difficult prey. Another notable example is the black widow, whose tiny body
produces one third as much venom as a rattlesnake.
