对30多种螃蟹的视觉显示的研究允许对短吻类进行一些概括。显示器分为两组，侧Merus和前螯。每组包含三个主要的显示亚型，它们起源于强度的离散信号。在某些属中，侧Merus的几种特殊仪式已经进化出来。侧肢似短尾类的原始显示类型，至今仍存在于大多数蟹类中。据推测，前螯虫起源于一种专门的求偶展示，但在一些属中已被用于一般的争斗用途。
Study of the visual displays of more than 30 species of crabs allows some generalizations on the Brachyrhyncha. The displays fall into two groups, the Lateral Merus and the Chela Forward. Each group contains three major subtypes of display, which originated as discrete signals of intensity. Several special ritualizations of the Lateral Merus have evolved in certain genera. The Lateral Merus seems to be the primitive type of display in the Brachyura and still exists in most crabs. It is speculated that the Chela Forward arose from a specialized courtship display but has been adopted for general agonistic use in some genera.
