1992年在韩国江华岛观察到的巨蟹Ilyoplax pingi通过堆放从洞穴中挖出的泥土，在洞穴入口处筑起一个土堆。这些土丘是由挥舞的和不挥舞的雄性、产卵的和非产卵的雌性建造的。有土丘的螃蟹最宽处的洞穴直径往往比无土丘的螃蟹大，但它们之间的洞穴深度没有差异。在暴露后期，当螃蟹的表面活性下降时，堆密度增加。土堆拆除和重建实验表明，土堆的存在具有阻止邻近螃蟹的作用。
The ocypodid crabIlyoplax pingi, observed in Kanghwa I., Korea in 1992, builds a mound at the burrow entrance, by piling mud dug out from the burrow. The mounds were made by both waving and non-waving males, and by both ovigerous and non-ovigerous females. The burrow diameter at the widest part tended to be larger in crabs with mounds than in crabs without mounds, whereas the burrow depth was not different between them. The mound density increased in the late exposure period, when the crabs' surface activities declined. Mound removal and rebuilding experiments revealed that the presence of the mounds has the effect of keeping neighboring crabs away.
