Answer: Toothcomb

These unique teeth can be found in the mouth of a colugo, a gliding mammal found in Southeast Asia. There are only two modern species of colugo: Malayan and Philippine. They are also known as a flying lemur, since they are arboreal and spend the majority of their lives in the trees.  

These specialized teeth are bottom incisors used for grooming, but may also be used to obtain food. For colugos, their toothcombs are individual incisors that are serrated with many fine lines in each tooth that are used to divide hairs. There may even be up to 20 of these sharp points in a single tooth.
