Brazil has an Island with so many venomous snakes that humans are banned from it.
Nicknamed Snake Island, it is the home to the Golden Lancehead Viper, which is the one of the most venomous snakes in the world.
Interestingly enough, the Golden Lancehead is the only species of snake that lives in the island, and it’s considered in danger of extinction. A documentary from the discovery channel states that there’s as many as one snake per 10 square feet. For many years, the island’s only inhabitant was the lighthouse keeper, but nowadays the Brazilian Navy bans civilians from visiting the island. It is estimated that there’s anywhere between 5,000-7,000 snakes in the island.
