Most Venomous Spider in the World: Funnel-Web Spider
By: Two species of funnel-web spiders from the Atracidae family, the Sydney funnel-web and tree-dwelling funnel-web spiders, are among the most venomous spiders globally. Their bites can be fatal if untreated, and they often come into contact with humans. While female bites are harmless, male bites can incapacitate and potentially kill victims. When threatened, these spiders may bite multiple times, with symptoms appearing within an hour, including severe pain and disorientation. Fortunately, an effective antivenom has been developed, saving many lives. Funnel-web spiders are typically blue-black, black, brown, or dark purple, measuring 0.5 to 2 inches, with females being larger than males. Notably, a male with a four-inch leg span was recorded in 2016.
