Aye-ayes: specialists on structurally defended resources.

During the course of a 2-year field study on aye-ayes (Daubentonia madagascariensis), data were collected on dietary composition, food acquisition and structural properties of food resources. Aye-ayes in this study sampled remarkably few species from a variety of food types. A majority of these resources were heavily structurally defended and therefore difficult of access for other mammals. Aye-ayes used their modified finger and anterior teeth to harvest most of these resources.
