The video explains how the moon's gravitational pull affects tides, influencing the life cycles of certain animals like the grunion fish. Grunion fish, found along California's coast, uniquely breed on land during specific moon phases. They lay eggs in the sand during high tides, which hatch when the next high tide occurs, allowing the young fish to return to the sea. This cycle is intricately linked to the moon's phases, demonstrating the profound impact of celestial bodies on earthly life.
