AnAge entry for Eulemur fulvus

Classification (HAGRID: 03134)
Taxonomy	Kingdom: Animalia Phylum: Chordata Class: Mammalia (Taxon entry) Order: Primates (Taxon entry) Family: Lemuridae Genus: Eulemur
Species	Eulemur fulvus
Common name	Brown lemur
Lifespan, ageing, and relevant traits
Maximum longevity	35.5 years (captivity)
Source	ref. 671
Sample size	medium
Data quality	acceptable
Observations	One specimen lived 35.5 years in captivity. Assuming it was received as an adult, it could have lived to the age of 37 or even more because its exact date of death is unknown. A hybrid between a brown and a black lemur reportedly lived 39.3 years [0671].
