Record longevity from banding studies is 37.1 years [0970]. There are some discrepancies regarding age at sexual maturity with estimates ranging from 3 months to over one year.
Studies have shown that there is no relationship between telomere length and age in these animals. Telomerase was not found to be expressed in these animals' blood or fibroblasts. However, genes related with DNA repair and the prevention of DNA damage may contribute to the maintenance of telomere length in animals of this genus [1349]. Telomere length dynamics might be associated with environmental stressors, like climate, instead of age [1359]. These animals have also been shown to express genes with age differently from other mammals, particularly in regards to DNA repair, autophagy, immune response and tumour suppression [1358].
