Large body size of ectothermic species can be correlated with high life expectancy. We assessed the longevity of the World's largest chameleon, the Parson's chameleon Calumma parsonii from Madagascar by using skeletochronology of phalanges taken from preserved specimens held in European natural history museums. Due to the high bone resorption we can provide only the minimum age of each specimen. The highest minimum age detected was nine years for a male and eight years for a female, confirming that this species is considerably long living among chameleons. Our data also show a strong correlation between snout-vent length and estimated age.
变温动物的大体型可能与高预期寿命相关。我们通过对保存在欧洲自然历史博物馆的标本的指骨进行骨骼年代测定，评估了世界上最大的变色龙——来自马达加斯加的帕森斯变色龙（Calumma parsonii）的寿命。由于骨吸收严重，我们只能提供每个标本的最小年龄。检测到的最高最小年龄，雄性为9岁，雌性为8岁，这证实了该物种在变色龙中寿命相当长。我们的数据还显示吻肛长度与估计年龄之间存在很强的相关性。
