Quick answer
Aye-ayes (Daubentonia madagascariensis) typically live around 20–23 years in the wild (long-lived for a lemur). Wild averages fall when predation, disease, or habitat loss rise; managed populations can live longer with stable food and veterinary care.
Key takeaway

Aye-aye lifespan in the wild
Field and museum records place most aye-ayes near 20–23 years in the wild (long-lived for a lemur). That figure blends ages at death across regions, so treat it as a planning range. Body size (2–3 kg (4.4–6.6 lb)) and risk lifestyle both shape the average.
What shortens aye-aye lives
Predation, infectious disease, injury, food shortages, and habitat fragmentation cut survival. Roadkill and human conflict matter wherever aye-ayes share landscapes with people.
What helps aye-ayes live longer
Connected habitat, low chronic stress, and reliable food support longevity. For captive or domestic relatives, species-correct diet and veterinary screening matter more than generic “pet” advice.
Aye-aye life stages
Juveniles usually face higher mortality than prime adults. Older animals may move less, show dental wear, or lose body condition — useful signs when ageing aye-ayes in the field.
Diet and ecological role
Aye-ayes feed on omnivore — insect larvae, fruit, nectar, and fungi. Foraging shifts with season and local abundance. As mammals, they influence food webs — controlling prey, dispersing seeds, or shaping habitat through feeding and movement.
Conservation and coexistence
Listed as Endangered on the IUCN Red List. Habitat loss, hunting, and climate change threaten many populations. Responsible ecotourism and community conservation help in parts of their range. Never approach or feed wild aye-ayes.
