Brazil's Snake Island: Myth vs. Reality
24 Sep
Summary
- Queimada Grande island is home to the golden lancehead snake.
- Online claims of thousands of snakes are exaggerated.
- Access is restricted to protect the species and its habitat.
Queimada Grande, an island off Brazil's São Paulo coast, is popularly known as Snake Island due to its sole inhabitant, the golden lancehead snake. This unique species evolved in isolation, adapting to feed on birds rather than rodents, unlike its mainland relatives.
Contrary to sensationalized online accounts, scientific research from 2021 estimated the golden lancehead population to be around 2,899 individuals, a far cry from claims of hundreds of thousands. A separate 2026 study revealed that a significant majority of online sources about the island contained misinformation and sensationalist language.
Access to Queimada Grande is restricted, a measure implemented to protect the highly endemic golden lancehead. Potential threats to the species include illegal snake trade, invasive species, disease, and natural disasters. Conservation efforts are hampered by the widespread misinformation surrounding the island and its snake population.
