Snake Island, Brazil

The famous Snake Island in Brazil (or what the locals call  Ilha da Queimada Grande) is home to some of the world’s rarest snakes such as the golden lancehead pit viper. The whole island has 43 hectares of landmass, which is enough for a small village. However, local authorities won’t allow people to live here and have restricted any entry to the island because of the snakes residing on it.

According to local researchers, there are about one to five snakes in every 10 square feet inside the island. While the Brazilian authorities have cut off any access to the island, they do allow the country’s Navy and a couple of researchers to be stationed on the island. We have to give their government a huge credit for protecting the public and the population from these rare snakes.
