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 ecological niche of a woodpecker. It taps on trees to find grubs, then gnaws holes in the wood and inserts its finger to pull the grubs out. The aye-aye is the only species in the family Daubentoniidae.
