欧洲招潮蟹把泥球放在它们的洞口周围。雄性和雌性都放置了泥球，但在泥球行为上，两性之间存在着重大差异，这表明雌性的泥球是挖洞的副产品，而雄性的泥球可能有额外的功能。实验中去除雄鱼的泥球后，雄鱼间相互作用的数量和强度显著增加。实验中，视觉隔离的雄性花更长的时间做泥球，更少的时间挥手。在二元选择测试中，与没有泥球的虚拟雄性相比，雌性更有可能接近有泥球的虚拟雄性，在这些雄性附近待的时间更长，更有可能进入它们的洞穴。同样的模式在有30个而不是20个泥球的男性身上也很明显。这些结果与坦格里泥球的双重功能是一致的：减少邻近雄性之间攻击性相互作用的数量和强度，并吸引雌性。版权所有1998动物行为研究协会。版权所有1998动物行为研究协会。
European fiddler crabs place mudballs around their burrow openings. Both males and females placed mudballs, but there were major differences between the sexes in mudballing behaviour, suggesting that the female's mudballs were a by-product of digging out the burrow whereas the male's may have additional functions. When the male's mudballs were removed experimentally, the number and intensity of male-male agonistic interactions increased significantly. Experimentally visually isolated males spent longer making mudballs and less time waving. In a binary choice test, females were more likely to approach dummy males with mudballs, spent longer near these males and were more likely to enter their burrows than dummy males without mudballs. The same pattern was apparent for males with 30 rather than 20 mudballs. These results are consistent with a dual function for mudballs in U. tangeri: to reduce the number and intensity of aggressive interactions between neighbouring males and to attract females.
