Three brothers in Bolivia were hospitalized after they were bitten by a black widow. According to officials they made the spider bite them thinking it would turn them into Spider-Man. The brothers age 12,10, and 8 were found by their mother crying. The kids experienced fevers, tremors, and muscle pains and were released a week later.
Black widows are one of the most venomous species in North America. The spiders are not aggressive but will bite in self defense.
