马蹄蟹Limulus polyphemus在墨西哥湾东北部最高涨潮时的桑迪上产卵，埋在水面以下约18厘米处。当它们孵化时，幼虫必须从埋藏的巢穴转移到海洋环境中。在野外，幼虫的巢移到沙面，并在满月之夜的春季高潮出现。它们也可能被与风暴有关的巨浪释放。没有释放发生在春季高潮与新月。在实验室中，幼虫被认为是积极的，无论是在环境和DD光周期。在满月和新月的时候活动达到高峰，幼虫在除新月之外的所有月相都是正趋光的。一个模型来解释所观察到的领域的行为，根据实验室的活动和光响应。
The horseshoe crab Limulus polyphemus lays its eggs on sandy beaches at the level of the highest high tide in the northeastern Gulf of Mexico, buried approximately 18 cm below the surface. When they hatch, the larvae must move from the buried nest site into the marine environment. In the field, nests of larvae move to the sand surface and emerge at the spring high tide on the night of full moon. They may also be released by heavy surf associated with storms. No release occurs on the spring high tides associated with new moon. In the laboratory, larvae are seen to be nocturnally active, both under ambient and DD photoperiods. Activity peaks at times of full and new moons, and larvae are positively phototatic at all lunar phases except new moon. A model to account for observed field behavior in light of laboratory activity and light responses is presented.
