My, long fingers you have! These awesome elongated digits belong to an Aye-aye, a species of lemur native (like all lemurs) to the island of Madagascar, off the eastern coast of Africa in the Indian Ocean.

Aye-ayes are the world’s largest nocturnal primate and they use their spectacularly long middle fingers, not to make equally spectacular rude gestures, but to find food:

The aye-aye taps on trees to find grubs, then gnaws holes in the wood using its forward slanting incisors to create a small hole in which it inserts its narrow middle finger to pull the grubs out. This foraging method is called percussive foraging.

The only other animal species known to find food in this way is the striped possum. From an ecological point of view the aye-aye fills the niche of a woodpecker, as it is capable of penetrating wood to extract the invertebrates within.
