Ilha de Queimada Grande, known as “Snake Island”, located 20 miles off the coast of Brazil, is home to thousands of highly venomous Golden Lancehead vipers — as many as five per square yard. The snakes are so dangerous that people are forbidden to land on the island. It is the only place in the world that is home to the deadly viper, whose potent venom can not only kill people but also melt human flesh. (From Ripley’s Believe It Or Not: Eye-Popping Oddities)
