Like all lemurs, the ruffed lemur has special adaptations for grooming, including a toilet-claw and a toothcomb. Red ruffed lemurs dedicate a significant amount of their time to grooming themselves and each other. The lower incisors of the teeth grow forward together in a line with light spacing, to create the toothcomb, which enables them to groom their long, soft fur. The toothcomb has also been implicated in playing a secondary role in olfaction (Cuozzo & Yamashita, 2006, p. 75-76). The toothcomb may function to stimulate and distribute olfactory secretions throughout the body, directing such secretions to the vomeronasal organ (Cuozzo & Yamashita, 2006, p. 75-76). The red ruffed lemur toothcomb may be seen in picture below.
