While lunar rhythms are commonly documented in plants and animals living in terrestrial and shallow-water environments, deep-sea organisms have essentially been overlooked in that respect. This report describes evidence of lunar periodicity in the reproduction of 6 deep-sea species belonging to 2 phyla. Occurrences of gamete release in free spawners and larval release in brooders exhibited significant peaks around the new and full moons, respectively. The exact nature of this lunar period (endogenous or exogenous rhythm) and its adaptive significance in the deep sea remain elusive. Current knowledge suggests that proxies of moon phases at depth may include fluxes in particulate matter deposition, cyclic currents, and moonlight for species living in the disphotic zone.
虽然月球节律在生活在陆地和浅水环境中的植物和动物中被广泛记录，但深海生物在这方面基本上被忽视了。本报告描述了属于两个门的 6 种深海物种繁殖中的月球周期性的证据。自由生殖者的配子释放和育幼者的幼虫释放分别在新月和满月前后出现明显的高峰。这种月球周期的本质（内源性或外源性节律）及其在深海中的适应意义仍然难以捉摸。目前的知识表明，深度处月相的替代物可能包括颗粒物质沉积、循环流和生活在弱光层的物种的月光的变化。
