Sir Isaac Newton’s theory of gravity speaks that every particle attracts every other particle with a force that depends on their masses and the distance between them. The moon constantly attracts the earth behaves like a loose garment that can be pulled out from the body to fall back again. It implies that every day, when the moon is directly overhead, the water of the earth flows out towards the moon, and causes high tide. Hence, during the full moon, the attraction is greater than the normal. Dr. Lyall Watson writes in Supernature (London, 1973, p. 49) that, “Every drop of water in the ocean responds to this force, and every living marinal animal and plant is made aware of the rhythm. The lives of those that inhabit the margins of the seas depend entirely on this awareness.”
Sir J.G. Frazer has discussed the influence of the new moon and propounded that it brings fertility and causes growth in agriculture (The Golden Bough, London, 1956, p. 128). Sir Frank Browne writes in his remarks in 1964 that, “The life of the oyster has a marked rhythm that corresponds to the tidal rhythm of the waters. The fascinating thing; however was that the behaviour of all the oysters had altered in exactly the same way, and they were still keeping time with each other. The oysters had adopted a new rhythm and now opened up at the time of tide. This is the first piece of scientific evidence to show that even an organism living away from the ocean tides could be influenced by the coming out of new moon” (Living Organism, London, 1969, p. 12).
The small silver fish, known as Grunion survives on its response to the lunar cycle. Shortly after the new moon from March to August, the Grunion appears on the surface on the shores of California. The Grunion leave their eggs buried in the wet sand undisturbed for two weeks, because the waves of water will not come until new moon. When the spring tide occurs, the larvae have completely developed and they break out of the eggs and swim away through the surf. The ability of the Grunion to reproduce is thus controlled by the new moon.
