Madagascar is a biodiversity hotspot, hosting a multitude of wildlife species found nowhere else on Earth. There are more than 100 taxa of lemurs; this, coupled with their island isolation, makes them a stunning example of diversification through evolution. The aye-aye is the largest nocturnal lemur, best known for its distinct appearance and unusual diet. The aye-aye has large radar-like ears and specialized middle fingers designed specifically for detecting and pulling out grubs from under tree bark. Its robust and ever-growing incisor teeth allow this uniquely adapted lemur to crack open hard objects, including nuts, in order to gain access to highly nutritious foods.
