She had not eaten for five days and had been unwell, the park said in a statement announcing her death.

Baby Lemur Makes London Zoo Debut
London Zoo is welcoming the first ever baby aye-aye lemur just in time for Halloween.
The creepy-looking creature was actually born on July 1 but has only emerged from its secluded nesting box for the first time this week.
The species of lemur (formally known as Daubentonia madagascariensis) are unique in that they have an unusually large middle finger and are associated with doom in their native Madagascar. Natives there believe that if an aye-aye points its long finger at you, death is not far away.
Zookeepers expressed their excitement at the birth although they only saw the baby recently as it has been hiding in its nest box.
