Entry ban on the island home to the world's most dangerous snakes

Located in the Atlantic Ocean, approximately 145 kilometers off the coast of southeastern Brazil and known popularly as "Snake Island," Ilha da Queimada Grande has been closed to the public due to the extreme danger it poses. Following recent scientific studies and security reports, the closure of the island to civilian visitors has been made official.

The island is famous for the Golden Lancehead vipers, which are found only in this region. Experts estimate that there are between 2,000 and 4,000 of these rare snakes on the island. Measurements indicate that the number of snakes per square meter poses a serious threat to human life.

A PERSON BITTEN BY THE SNAKE DIES WITHIN 1 HOUR

Scientific research has revealed that the venom of the Golden Lancehead viper is much more potent than that of similar species on the mainland. Due to the island's geographical isolation, access to emergency medical intervention is nearly impossible. A person bitten by the snake can lose their life within an hour if not treated.

According to the official statement, access to the island, which will henceforth be conducted under the supervision of the national navy, has been strictly restricted. Only biologists or ecologists wishing to conduct scientific research, or soldiers tasked with maintaining the lighthouse on the island, will be able to enter with special permission. It has been made mandatory for all these teams to have a professional doctor with them due to health risks.

These new measures aim to both protect the island's ecosystem and ensure the safety of human life.
