Brazilian Wandering Spider
10 deaths total
Tarantulas get all the glory because of their looks, but Brazilian wandering spiders carry the real venom. They’re known to “wander” into homes and cars of populous regions to terrorize inhabitants with their frightening appearance and extremely dangerous venom. If a man is bitten by a Brazilian wandering spider, he sustains a painful erection for four hours and then dies. An antidote has been identified and successfully used to combat the fatal effects of the venom.
