Off-Limits “Snake Island” Is Full of Venomous Pit Vipers
By Atlas Obscura, July 15, 2013
Off the shore of São Paulo lies an island forbidden to visitors, by order of the Brazilian Navy. They have a good reason: Ilha Queimada Grande, “Snake Island,” is covered with deadly Golden Lancehead vipers.
Unique to the island, this species of serpent is believed to have the fastest acting venom of any Lancehead viper. The effects of its bite include bleeding orifices, brain hemorrhaging, and kidney failure.
The density of snakes on the island is estimated at one per square meter, many of which are found overhead, hanging from the trees. In other words: death, every 3 feet, in all directions.
