Vipers are among the most developed and most fascinating snake species. Color and pattern of each species such as Asp Viper, Common Adder, Nose-horned Viper, Milos Viper, Ottoman Viper and Ocellated Mountain Viper are amazing each time we look at them. All photographs of this calendar were taken in the wild, in the natural habitats of the different shown viper species.
