The gremlin-like, endangered aye-aye makes its home in the tropical forests of Madagascar, a large island off the coast of Africa. These nocturnal lemurs use their big ears to listen for squirming grubs (young beetles) beneath the bark of trees. Once an aye-aye hears that a tasty meal is close by, it uses its sharp teeth and long middle finger claw to dig for it. Sounds like a tasty snack!
