Western hognose snake — a medium-sized non-venomous snake. It lives in dry areas of the southwestern United States and uses a large scale on the tip of its snout to search for prey in the soil.
The western snake with a plate on its nose differs from other snakes by a large scale on its snout that helps dig the ground. It regulates the population of lizards and serves as prey for birds of prey and mammals.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
