Scopimera globosa是一种小型的半足纲蟹，当它不与另一个个体直接互动时，它会有节奏地抬起或放下它的身体和两个螯，以摆动的方式展示。为了确定挥动是否是一种社会信号，并推断其可能的功能，我们在野外围栏中控制了螃蟹的性别和密度，并记录了雄性螃蟹挥动的频率。周围有很多雌性邻居的雄性比周围有很多雄性邻居的雄性挥手的频率要高得多。被关在笼子里的雄性很少挥手。因此，雄性在雌性在场的情况下，尤其是在高密度的情况下，挥动的次数最多，而在其他雄性在场的情况下，挥动的次数最少，这表明挥动可能在雌性获得中起作用。
Scopimera globosa, a small ocypodid crab, rhythmically raises and lowers its body and both chelae in a waving display when it is not interacting directly with another individual. To determine whether waving is a social signal and to deduce its possible function, we manipulated the sex and density of crabs in a field enclosure and recorded the waving frequency of males. Males with abundant female neighbors waved significantly more often than when the same males were caged with abundant male neighbors. Males caged with fewer neighbors of either sex seldom waved. Thus, males waved most in the presence of females, especially at high density, and least in the presence of other males, suggesting that waving may function in female acquisition.
