Lunar rhythm

Japanese: 月周リズム - げっしゅうリズム（英語表記）lunar rhythm

It is also called lunar rhythm. Life phenomena related to the phases of the moon are widely seen in coastal organisms, and were already known in ancient Greece and China. Eunice fucata , a member of the family Euniceidae, which lives on the shallow seabed in Florida, performs reproductive schooling around the time of the waning quarter moon from late June to late July, and this has been known for a long time as the Atlantic palolo. Japanese tubular fish also perform reproductive schooling a few days after the new moon and full moon in October and November. On the sandy beaches of Southern California, large schools of grunion fish of the family Anserinidae come to spawn on the nighttime spring tides a few days after the new moon and full moon from March to September.

太陰リズムともいう。月の位相と関連した生命現象は海岸の生物に広く見られるもので，すでに古代のギリシアや中国で知られていた。フロリダ地方の浅海底に生息するイソメ科のEunice fucataは6月下旬から7月下旬の下弦の月のころに生殖群泳を行い，これは大西洋パロロpaloloと呼ばれ古くから知られている。日本産のイトメも10月から11月の新月と満月の数日後に生殖群泳を行う。南カリフォルニアの砂浜には3月から9月にかけて新月や満月の数日後，夜の大潮に乗ってグルニオンgrunionというトウゴロウイワシ科の魚が大群をなして産卵にくる。
