Among crabs, eggs are attached to the tail of the female and carried for a length of time that varies with the species. Egg hatching is precisely timed with respect to environmental cycles such as lunar, light-dark and tidal cycles. It is proposed here that egg hatching is controlled by the developing embryo rather than the female carrying the mass of embryos. Breakage of an initial few brings about the release of certain peptides and this provides a chemical clue inducing the female to bring about behavior which results in the synchronized release of crab larvae. The proposed research is designed to answer questions that will increase our understanding of the egg hatching process which is precisely timed to enhance the larval survival and transport in estuarine and coastal areas.

在螃蟹中，卵附着在雌性的尾巴上， 携带的时间长短因物种而异蛋 孵化是精确的时间相对于环境周期 例如月球、明暗和潮汐周期。这里提出 卵的孵化是由发育中的胚胎控制的， 而不是携带大量胚胎的雌性。断裂 最初的几个导致某些肽的释放， 提供了一个化学线索，诱导雌性 导致螃蟹同步释放的行为 幼虫 这项拟议中的研究旨在回答一些问题， 增加我们对鸡蛋孵化过程的了解， 精确地定时，以提高幼虫的存活率和运输， 河口和沿海地区。
