Ilha da Queimada Grande sits in the Atlantic Ocean about 90 miles off the coast of southeastern Brazil is the most deadliest place on earth.
About 90 miles off the southeastern coast of Brazil, there is an island where no local would ever dare tread. Legend has it that the last fisherman who strayed too close to the shores of Snake Island was found days later adrift in his own boat, lying lifeless in a pool of blood.
This mysterious island, also known as Ilha da Queimada Grande, is so dangerous that Brazil has made it illegal for anyone to visit. And the danger on the island comes in the form of the golden lancehead pit vipers – one of the deadliest snakes in the world.
The lanceheads can grow to be over a foot-and-a-half long and it’s estimated that there are between 2,000 and 4,000 of them on Snake Island. The lanceheads are so venomous that a human bitten by one could be dead within an hour.
How Snake Island Became Infested With Serpents
Snake Island is uninhabited now, but people used to live there for a short period up to until the late 1920s when, according to legend, the local lighthouse keeper and his family were killed by vipers that slithered in through the windows. Today, the navy periodically visits the lighthouse for upkeep and makes sure no adventurers are wandering too close to the island.
how many snakes are actually on Snake Island has long been debated, with since-debunked estimates ranging as high as 400,000.
Another local legend claims that the snakes were originally introduced by pirates seeking to protect buried treasure on the island.
In reality, the vipers’ presence is the result of rising sea levels – a less exciting origin story than paranoid pirates to be sure, but still interesting. Snake Island used to be part of Brazil’s mainland, but when sea levels rose over 10,000 years ago, it separated the landmass and turned it into an island.
he animals that wound up isolated on Queimada Grande evolved differently from those on the mainland over the course of millennia, the golden lanceheads in particular. Since the island vipers had no prey but birds, they evolved to have extra-potent venom so that they could almost immediately kill any bird. Local birds are too savvy to be caught by the many predators that inhabit Ilha da Queimada Grande and the snakes instead rely on birds who visit the island to rest as food.
Why The Vipers Of Brazil’s Snake Island Are So Dangerous
Lancehead snakes, which are the golden lanceheads’ mainland cousins, are responsible for 90 percent of all snake bites in Brazil. A bite from their golden relatives, whose venom is up to five times more potent, is less likely to actually happen due to their island isolation. However, such an encounter is far more likely to be lethal if it does happen.
There are no fatality statistics of the golden lanceheads (since the only area they inhabit is cut off from the public), however someone bitten by a regular lancehead faces a seven percent chance of death if untreated. Treatment does not even guarantee a lancehead bite victim will be saved: there is still a 3 percent mortality rate.
The golden lancehead pit vipers of Snake Island are some of the most endangered snakes on planet Earth.
It’s hard to imagine why anyone would want to visit a place where a painful death lurks every few feet.
However, the vipers’ deadly venom has shown potential in helping to combat heart problems, leading to something of a black market demand for the venom. For some lawbreakers, the lure of the money is incentive enough to risk almost certain death on Ilha da Queimada Grande.
