The World’s 25 Strangest Animals

Aye-Aye

Due to its bizarre appearance and unusual feeding habits, the aye-aye is considered by many to be the strangest primate in the world. It is the world’s largest nocturnal primate. Its unusual physical characteristics include incisors that are continually growing (unique among primates), extremely large ears, and a middle finger which is skeletal in appearance, which the animal uses as its primary sensory organ.
