The Golden Lancehead is a highly venomous snake species found exclusively on Isla da Queimada Grande, also known as Snake Island, off the coast of Brazil. This snake is notable for its striking yellowish coloration and is adapted to its isolated environment, where it preys primarily on birds. Due to its limited habitat and specialized diet, the Golden Lancehead is considered critically endangered. The island is off-limits to the public, which helps protect this unique species from habitat destruction and human interference. Conservation efforts are essential to ensure its survival in the wild.
