我们研究了意义的沉默裸露的牙齿显示在一组圈养的山海关（山海关狮身人面像）。我们观察到的显示主要是在积极的互动，在这种情况下，他们可以宣传发送者的和平意图，虽然有时他们也发生作为一种回应侵略。我们没有发现激动相互作用的方向和显示之间的关系。这两种变体的显示，与关闭或打开的下巴，表现出大多数对称的模式。这种闭齿型和开齿型的进化趋同可能与山鸡的优势型有关。
We studied the meaning of silent bared-teeth displays in a captive group of mandrills (Mandrillus sphinx). We observed the displays mostly in positive interactions, in which case they could advertise the sender's peaceful intentions, though at times they also occurred as a response to aggression. We found no relationship between the direction of agonistic interactions and the display. Both variants of the display, with closed or open jaws, exhibited mostly symmetrical patterns. The evolutionary convergence of the closed and open bared-teeth displays might be related to the dominance style of mandrills.
