Observations

Grey mouse lemurs appear to be among the shortest lived primates [0463]. One captive specimen lived for 18.2 years [0671]. In the wild these animals experience very high levels of extrinsic mortality. Wild grey mouse lemurs have shorter lifespans, however the oldest animals display no evidence of functional senescence. In contrast, captive grey mouse lemurs show senescence in their ability to regain lost body mass and a reverse sex bias in lifespan (favouring males) [1189]. Captive grey mouse lemurs are generally weaker and show earlier decline in physical strength than wild animals. Wild female grey mouse lemurs are generally stronger than their male counterparts [1190].
