Observations: Although the longevity of this animal is unknown, an increased reproductive output with age has been reported [0019]. Animals from different geographical locations have been shown to have different life histories presumably due not only to environmental factors but also because of physiological differences. In New Jersey, lizards grow slower than in Nebraska, reach maturity at later ages, and have a longer lifespan [0641].
