21. They Have Dangerous Cousins
While the Golden Lancehead vipers had made this island their sole territory, they are not the only kind of Lancehead snakes present in Brazil. Their mainland cousins, simply called Lancehead snakes, are responsible for no less than a whopping 90% of all snake bites in Brazil!
This is why scientists and researchers are closely studying both the Lancehead as well as the Golden Lancehead vipers. This will help them understand the toxicity levels of both the venoms, and hopefully help them understand how to prevent such bites from taking place.
