A serpentoponus is a genus of venomous snakes belonging to the family Viperidae, specifically within the subfamily Crotalinae, commonly known as pit vipers. These snakes are characterized by their heat-sensing pits located between their eyes and nostrils, which help them detect warm-blooded prey. They are primarily found in tropical and subtropical regions, and some species are known for their striking coloration and potent venom. Serpentoponus species play important roles in their ecosystems as both predators and prey.
