The common smooth snake is a small non-venomous snake up to 80 centimeters long. It lives in Europe on dry sunny areas and mainly feeds on lizards.
The copperhead differs from the viper by its round pupil and smooth scales without a keel. It is important for nature because it regulates the population of lizards and small rodents.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
