This is medea the aye aye showing off the aye aye's most intersting adaptation, their middle finger! Aye-ayes are referred to as “percussion foragers” because they use their middle finger to tap on wood, listening for the movement of larvae hidden inside. If they hear movement, they use their rodent-like incisors to gnaw into the bark exposing the larvae and then insert their elongated middle finger to extract the larvae. They are the only primates thought to use echolocation to find prey. | Cin
