There are a lot of strange animals in the world, most of which you've never heard of, on land and under the sea. One such critter is the Aye-Aye, a googly-eyed member of the lemur family and strangely cute.
They are nocturnal lemurs with a very unusual build, and have large ears and rat-like teeth that perpetually grow! Aye-Ayes are the world's largest nocturnal primates. They tap on trees to locate insects based on percussion feedback, bore a hole with their teeth and use their long middle finger to extract and eat the insects.
Classified as an endangered species, the Aye-Aye is native to Madagascar. In the United States, you can find them at the Philadelphia Zoo and the Duke University Lemur Center.
