SNACKTIME TAP-TESTING
This picture was taken during behavioral studies conducted at the Duke Lemur Center at
Duke University in Durham, North Carolina. Dr. Ehsan Dehghan-Niri is feeding an aye-aye
by placing its favorite food in his hand, forming a fist to resemble a cavity. The aye-aye uses
its specialized middle finger, which it employs for tap-testing in the wild, to probe the hand,
mimicking its natural foraging behavior. Since aye-ayes are nocturnal, the red lighting repli-
cates their natural nighttime environment, ensuring they remain comfortable and exhibit
typical behaviors.
