The tripled checkered lizard is a species of lizard that lives only in the state of Colorado in the USA. All individuals of this species are females and reproduce without the participation of males through parthenogenesis.
The species is distinguished by the complete absence of males and a triploid chromosome set. It helps control insect populations in nature and serves as an example of an unusual reproductive method in animals.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
