The highest concentration of one of the most poisonous snakes in the world is located about 90 miles off the coast of Santos, Brazil, on a small, craggy chunk of otherwise uninhabitable land. It’s known as Ilha da Queimada Grande, or Snake Island, and it’s the only place you will find 2,000 or so of the wholly unique golden lancehead viper, or Bothrops insularis.When you step ashore, with a keen eye you spot one of these snakes roughly every 10 to 15 minutes after clearing the base of the island, and as many as one every six square yards in other parts of the island. This means, as you are walking through the waist-high brush, even with some good boots on, it’s like walking through a minefield that moves and, instead of blowing you into chunks, slowly paralyses you and liquefies your insides, as the golden lancehead does to the migrating birds it feeds on in the treetops.Well, “liquefying your insides” may be a stretch, but no one knows for sure because no one bitten has lived long enough even to be admitted to a hospital – or at least none of the researchers who accompanied VICE on their journey to Snake Island owned up to that fact. Nor did the Brazilian Navy, who allowed VICE exclusive access to document their annual maintenance inspection of Snake Island’s lighthouse – which has been automated ever since the 1920s, after the old lighthouse keeper ran out of food and disappeared while picking wild bananas in a small grove near the shore. According to legend, he and the members of his rescue party died one by one, all alone and in search of one another after each had been missing for some time.VICE’s editor-in-chief, Rocco Castoro, and senior producer, Jackson Fager travelled to snake island to nose around for themselves.
