people think they bring bad luck so they kill them 
Evil Eye of the Aye-Aye
In their native land of Madagascar, they were killed on sight for years. In fact, no sensible person would even venture out at night for fear of encountering the dreaded aye-aye. Not that the tiny, shy, nocturnal lemur was likely to attack, but it was an accepted belief that just seeing one would bring death.
The myth, unfortunately, was all too true for the unlucky aye-aye who has been nearly exterminated by farmers and villagers in fear of their demonic powers. Their fears don't seem so far-fetched, considering their unearthly appearance, which zoologist Gerald Durrell describes vividly in "The Aye-aye and I":
"In the gloom it came along the branches toward me, its round, hypnotic eyes blazing, its spoon-like ears turning to and fro like radar dishes, its white whiskers twitching and moving like sensors; its black hands, with their thin fingers, the third seeming terribly elongated, tapping delicately on the branches as it moved along."
The bizarre appearance and behavior are all easily and logically explained. The oddly tapping finger is locating the aye-ayes favorite meal of tasty grubs, who live just inches below the branch's surface, and the radar-dish ears are honing in on the hollow sound that gives them away. Chisel-sharp teeth will then tear away the layers of wood, and the long, bony middle finger is used to fish out the mouth-watering delicacy.
