The Great Basin collared lizard is a medium-sized lizard with characteristic black and white stripes on its neck. It lives in arid regions of western North America and is able to run quickly on its hind legs.
This species differs from other frilled lizards by the special pattern of the frill and adaptation to high-mountain deserts. It regulates the population of insects and small vertebrates in arid ecosystems.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
