The silent bared-teeth display is described in a captive group of Moor macaques (Macaca maurus). It occurs with either closed or open mouth and is observed in both affinitive and playful interactions. It does not appear to convey specific information about the social status of partners and should be viewed as a signal advertising the emitter's peaceful intentions. This is consistent with what is known for other species of macaques on Sulawesi island.
