Aye-Aye

Crouching on a tree branch, a hairy animal that looks like a cross between a raccoon and a rat lifts a long finger and taps on the trunk. It’s not politely knocking to see who’s home. Instead it’s trying to locate hollow spots beneath the bark where insects live. (It can tell that it’s found a cavity by the sound of the tapping.) Once it detects a hollow, the animal rips away the bark with its teeth and gobbles up the bugs. This curious creature is known as an aye-aye.
