Feared by some, revered by others, the Aye-aye (Daubentonia madagascariensis) is surely one of Madagascar's most bizarre lemurs. Unique among primates, the Aye-aye's front incisors grow continuously like a rodent, leading to the early belief that they were some sort of gigantic nocturnal squirrel. Equally unusual are its long bony middle fingers which are used by the animal to tap tree trunks for the sound of insect grubs inside and then extract them like a fish hook. Unfortunately, Aye-ayes have become gravely endangered from habitat loss and persecution by people: they are often killed on sight due to the superstition that they are an omen of death.
