Yes, the aye-aye (Daubentonia madagascariensis) is considered a nocturnal animal. It is a unique and rare primate species found only in Madagascar. The aye-aye has several adaptations that enable it to thrive in its nocturnal lifestyle.
The aye-aye's most distinctive feature is its elongated middle finger, which it uses to tap on trees and detect hollow chambers within. This tapping behavior is called "percussive foraging," and it allows the aye-aye to locate and extract insects and larvae hidden beneath the bark. This feeding strategy is more successful at night when insects are active and easier to detect.
