The Aye-aye was thought to be extinct in 1933, but was rediscovered in 1957. Nine individuals were transported to Nosy Mangabe, an island near Maroantsetra off eastern Madagascar, in 1966.Recent research shows that the Aye-aye is more widespread than was previously thought, but is still categorized as Near Threatened.
There are several Aye-ayes kept in zoos. The largest collection of Aye-ayes and the most successful breeding program with a current population of 22 individuals is at the Duke Lemur Center at Duke University, Durham, North Carolina, US. Several also reside outside of the US at various locations.{Citation needed date=July 2010}
