Bothrops insularis, commonly known as the golden lancehead pit viper, is a venomous snake found exclusively on Bothrops insularis in Brazil. This species is known for its distinctive yellowish coloration, which helps it blend into its tropical surroundings. It primarily preys on small mammals and birds, using its heat-sensing pits to locate warm-blooded prey. The golden lancehead is considered one of the most dangerous snakes in the world due to its potent venom, which can cause severe tissue damage and systemic effects in humans. Conservation efforts are crucial for this species, as its habitat is threatened by human activities and climate change.
