A venomous reptile is a type of animal that has the ability to inject venom into its prey or predators. The three most common venomous reptiles are the ASP, ADDER, and GILA. The ASP is a cobra species native to Africa and the Middle East. The ADDER is a viper species found in Europe, Asia, and North America. The GILA is a monster species native to the southwestern United States and northern Mexico. All three of these reptiles have the potential to be dangerous if provoked.
