lunar tidal rhythm

A lunar tidal rhythm refers to the periodic biological fluctuations in an organism that align with the cyclical environmental changes caused by the Moon's position relative to Earth. This rhythm is evident in the regular ebb and flow of oceans, which subjects coastal plants and animals to a predictable pattern of exposure and submersion. For instance, many shorebirds time their foraging to coincide with low tides when beaches are accessible.1

Reproductive cycles in some marine species are also synchronized with lunar phases, with specific events occurring during particular moon phases. This biological rhythm is a fundamental aspect of how many organisms interact with their environment, demonstrating a deep connection between celestial cycles and life on Earth.21
