Aye-Aye

Daubentonia madagascariensis

A strange-looking nocturnal lemur that taps on trees with a long, thin middle finger to find grubs inside.

About the Aye-Aye

Aye-ayes live across Madagascar in rainforests, dry forests and plantations, spending most of their time high in the treetops. They have long, coarse dark fur, large ears, yellow-orange eyes and a bushy tail. Their third finger is long, thin and bendy. They eat fruit, nuts and seeds, using that finger to scoop out the insides of fruit.[1]
