Spider venom is designed to kill or paralyze smaller prey, but that doesn’t mean it can’t do damage to a person. Some species can produce skin lesions or allergic reactions that result in fatalities, according to Britannica. Out of 43,000 spider species in the world, only 30 are responsible for human deaths. Brazilian Wandering Spiders (banana spiders) are the deadliest, and they are found in banana leaves. But don’t think they can’t get to you. A family in London was evacuated in 2014 after finding hundreds of potentially deadly spiders in a bunch of bananas. About 125,000 people die from snake bites every year, according to the World Health Organization (WHO); Another 400,000 people are permanently disabled or disfigured.
