Ilha de Queimada Grande, nicknamed Snake Island, is an island off the coast of the state of São Paulo, Brazil. It is home to a species of the Golden Lancehead Viper, which is one of the most venomous snakes in the world. Local legend claims that there are five snakes in every square meter. For a long time, the island’s only inhabitant was the island’s lighthouse keeper. Currently, the Brazilian Navy bans civilians from entering the island.
