在日本南部冲绳岛的堀川礁滩，研究了栖息在岩石中的巨蟹（Macrophamus boteltobagoe）的蜕皮和繁殖周期之间的时间关系。每天对蜕壳和雌蟹进行取样，以调查野外的蜕皮和繁殖周期。雌性螃蟹在实验室中饲养，以研究蜕皮和繁殖事件之间的时间组合。人们发现，野外种群中的大多数雌性在新月前后产卵，在下一次满月前一天孵化幼虫，并在幼虫释放后几天蜕皮。然而，在圈养条件下，也观察到连续育雏而没有中间的蜕皮。在成熟体型的雄性中，每月发生两次蜕皮高峰，而雌性每月仅出现一次蜕皮高峰。
Temporal relationships between molting and breeding cycles of the rock-dwelling ocypodid crab, Macrophthalmus boteltobagoe, were studied at Horikawa reef flat, Okinawa Island, southern Japan. Daily sampling of exuviae and female crabs were carried out to investigate molting and breeding cycles in the wild. Female crabs were reared in the laboratory to study the temporal combination between molting and breeding events. Most females of the field population were found to oviposite around the new moon, to hatch larvae on the day immediately prior to the following full moon, and to molt a few days after larval release. In captivity, however, consecutive brooding without intervenient molting was also observed. In mature-sized males, two peaks of molting occurred per month, in contrast with the females which showed only one peak of molting per month.
