Marine animals have evolved circatidal rhythms, aligning activities with the 12.4-hour tidal cycle, complementing circadian rhythms.

Marine animals have evolved circatidal rhythms, aligning activities with the 12.4-hour tidal cycle, complementing circadian rhythms.

These rhythms are well known in marine animals that respond to tidal cycles. However, similar 12-hour patterns have been observed in recent studies in terrestrial animals, such as mice and humans.

Tides, influenced by the Moon, Sun, and Earth's rotation, impact navigation, marine life, and weather. They cause Earth's crust to deform and vary globally, with the Bay of Fundy experiencing the ...
