How does the aye aye adapt?

The aye-aye has evolved an unusual set of adaptations to extract food from structurally defended resources. It's rodent-like front teeth allow it to chew through hard surfaces, such as nuts and wood. To find insect grubs burrowed in trees, the aye-aye has a skinny finger that it uses to tap with and bat-like ears that is uses to hear the resulting vibrations. This allows it to find the hollow spots in the wood. It then uses those teeth to create an opening in the tree and then fishes out the grub with its skinny, highly-dexterous finger.
