Snake Island (Ilha Da Queimada Grande), Brazil

Snake Island

Off the coast of Brazil is a tiny but incredibly dangerous island called Ilha da Queimada Grande which is fondly known as Snake Island. Snake Island is home to thousands of lethal venomous golden lancehead snakes (Bothrops insularis).

The golden lancehead is a species of pit viper which has an incredibly deadly venom known to cause more human mortalities than any other group of snakes in either North or South America. Its venom can cause swelling, kidney failure, intestinal bleeding, haemorrhaging of the brain, and can kill a human within one hour. There are estimated to be anywhere between 2,000 and 4,000 lancehead snakes on Snake Island.

The golden lancehead snake is not even the only snake species on the island, only the most dangerous. There are many varieties of snake on the island and only a small amount of non-venomous snakes. There is estimated to now be between one and five snakes per square meter.

The reason thousands of snakes are thought to have collected here due to rising sea levels containing them on the small island measuring no more than 43 hectares. The island was once was inhabited until the late 1920’s but now, for human protection, Snake Island is completely off limits to the public and it’s actually illegal to visit the island.
