The aye-aye (Daubentonia madagascariensis) is the sole member of its prosimian genus. It is a largely nocturnal animal, and lives in the wild in two small forest areas on the island of Madagascar. When full grown, the aye-aye has a body length of 45 cm, with a bushy tail 10 cm in length. Its main food source is beetle larvae. The aye-aye knocks on tree bark until it hears a hollow sound with its enlarged ears. It then bites through the bark and wood to locate the larvae. It uses its extended and slender middle finger to extract larvae from the interior. The aye-aye is now extremely rare, due to the destruction of its forest home, and is on the verge of extinction. The individual in the clip has been relocated to a protected island off north eastern Madagascar. The island has 7 aye-ayes, which roam freely but their diet is supplemented to enable the rangers to monitor these animals when they visit the feeding stations.
