Aye-Aye-A unique animal which has an unusual thin middle finger for THIS reason!
The nocturnal Aye-Aye lemur, native to Madagascar, possesses a uniquely thin and elongated middle finger crucial for its survival. This remarkable adaptation allows the Aye-Aye to locate wood-boring insects by tapping on trees and extracting them from their burrows. Combined with its exceptional hearing, nocturnal vision, and continuously growing incisors, the Aye-Aye is uniquely adapted to thrive in its environment.
