Ilha de Queimada Grande

A.K.A. Snake Island

Over at Forests.org, there's an article that opens with a description of, "A deserted island where the forest floor writhes with the world's most venomous vipers. A fisherman found dead on his boat, its deck awash with his blood. A lighthouse keeper and his family massacred in a nocturnal snake invasion of their isolated cottage home.
And no, Forests.org is not a site for terrifying Indiana Jones / Anaconda slash-fiction. You see, Ilha de Queimada Grande is a delightfully exotic sounding island off the coast of Brazil that plays host to a certain breed of exotic sounding snake known as the Golden Lancehead. This snake has one of the worst venoms in the world, which literally causes your flesh to rot off your bones.

Now you may be asking, "But, there are poisonous snakes in lots of countries. What's so special about this one tiny island?" Well that's an interesting question, and we are only too pleased to haunt your dreams by filling it in for you.
Remember how we mentioned the snakes only live on this one island? Well it's quite a densely packed island. In fact, the Brazilian Navy has forbidden anyone to visit the place, and they aren't doing that to protect the snakes. Conservative estimates range from the spine tingling one snake per square meter to the "drop dead from pants shitting fear" five snakes per square meter. Can you picture it? Allow us to help you:

Not pictured: The dead people just out of shot.

Now imagine five of those. Now imagine those five in an area that's smaller than your bed. Now imagine that writhing nest repeated over every inch of this God-forsaken place.
Let's back up and talk about that fisherman:
"I heard the story of the fisherman who went ashore to pick bananas, got bitten and somehow managed to struggle back to his boat. There, he bled to death and was found sprawled on the blood-soaked deck of his boat."
And the lighthouse keeper's family?
"The family ran in panic one night after snakes crawled in through their windows, so the story goes, and were bitten as they fled through the forest by vipers dangling from tree branches. Their bodies were found spread across the island when a navy vessel stopped to make a routine supply drop."

A young snake, receiving its terror-enhancing steroids, as is the snake custom on this island.

Yeah. Imagine just sleeping peacefully when snakes start crawling through your bedroom window and you know the only option is to run outside into the jungle where there are even more snakes and they all govern themselves because this is an island of snake monsters and you are the intruder. And you struggle through the underbrush, alone, scared, knowing that you will never make it back to civilization to punch that fucking Realtor who sold you a house on goddamned Snake Island.
