The Black Widow Spider
Probably the most notoriously infamous in this list, the Black Widow has a unique red hour glass mark on its belly. Commonly found in places that have constant weather conditions, a number of species are included in this name. Its reputation precedes it for good reason. 5 percent of those who were bitten suffered fatally while those who survived suffered extremely. The good news is that an anti venom is available. They love to stay in outhouses.
