Snake Island, or known as Ilha da Queimada Grande, is an island in Atlantic Ocean, Brazil, which is inhabited by thousands of snakes. This site is located about 90 miles off the Sao Paulo coast.
Around 11,000 years ago, the Atlantic Ocean levels risen since the last ice age and disconnected the this island from the mainland. The snakes were trapped on the island and needed to adapted with the new environment.
The snakes increased rapidly and evolved over thousands of years without human intervention and became the dangerous island.
Eventually, this island is strictly closed to the public by the Brazilian government to protect human and snake life.
The access to enter Snake Island is only given to the Brazilian Navy, selected research and conservation units.
