Aye-aye

"The Aye-aye (Daubentonia madagascariensis) is a primate native to Madagascar that combines rodent-like teeth with a long, thin middle finger to fill the same ecological niche of a woodpecker. It is the world's largest nocturnal primate, and is characterized by its unique method of finding food; it taps on trees to find grubs, then gnaws holes in the wood and inserts its elongated middle finger to pull the grubs out." - Wikipedia
