Aye Aye

True Wild Life | Aye Aye | The aye aye is a subspecies of lemur found on the south eastern African island of Madagascar. The aye aye are the biggest nocturnal primates in the world with some aye aye weighing more than 3kg! The aye aye is also one of the few solitary species of primate and therefore hunts alone for grubs and insects.

The aye aye has rodent-like teeth and a long, thin middle finger that fills the same ecological niche as a woodpecker. The aye aye taps on trees to find grubs, then gnaws holes in the wood and inserts its long middle finger into the hole to pull the grubs out. The aye aye is considered to be a near threatened species, possibly even endangered with very few aye aye left in the wild . The second subspecies of aye aye is thought to have become extinct at some point in the past 1,000 years.

The aye aye inhabits the forested and jungle areas of the east side of Madagascar, but the aye aye is also commonly found in bamboo thickets and are occasionally found hunting on the ground.

The adult aye aye has black or dark brown fur covered by white guard hairs on the neck of the aye aye. The aye aye's tail is bushy and shaped similar to the tail of a squirrel. The aye aye is also thought to have a rodent like face that is similar in shape to the face of a raccoon. The aye aye also has big, bright, beady, luminous eyes that help the aye aye to see better in the dark. The aye aye has very large teeth that grow continuously throughout the aye aye's lifespan.

The aye aye's rodent like features contrasted with the aye aye's monkey like body are probably the reason why scientists originally classed the aye aye as a rodent and then re-classed the aye aye as a primate after further studies.
