Black Widow Spiders
Black widow spiders are not much larger than the top joint of your finger, but they can certainly do a lot of damage for their size. The National Geographic states that its venom is fifteen times stronger than a rattlesnake’s, although it’s not as deadly as generally believed, with only a small number of people having ever been killed by a black widow.
However, its bite can provoke nausea, aching muscles, and breathing problems, which is bad enough! Recovering from the bite can take a few days, and some people still experience pain after a few weeks.
