Queimada Grande is a small island located off the coast of Brazil, specifically in the Atlantic Ocean. It is often referred to as Snake Island due to its large population of golden lancehead pit vipers, a highly venomous snake species found nowhere else in the world. The island covers about 43 hectares and is uninhabited by humans, primarily due to the dangers posed by the snakes. The Brazilian government has declared Queimada Grande a protected area, prohibiting public access to preserve its unique ecosystem. The island's dense vegetation and tropical climate provide a suitable habitat for the snakes, making it a subject of interest for researchers studying biodiversity and venomous species.
