The island so full of venomous snakes that humans are barely allowed to set foot there
Ilha da Queimada Grande, Brazil's Snake Island, hosts the unique golden lancehead pit viper. This critically endangered species evolved in isolation. While venomous, snakes are not aggressive unless provoked. Access is restricted to protect both humans and the fragile ecosystem. Researchers study this rare evolutionary example. The island offers a glimpse into nature's unique adaptations.
