    “Under” the full moon means nothing other than “when there happens to be a full moon”. Sharks don’t understand or care about the full moon.

      That’s what we used to think but then this article came out and changed everything we thought we knew about the relationship between sharks and Earth’s largest satellite. Sharks are, according to the article, the most lunarly attuned fish. Hammerhead sharks have been observed exhibiting behavior that is suggestive of an ability to predict eclipses. These sharks care enough about the moon to line their burrows with shells oriented along the path the moon takes through the sky.

            For that to make sense wouldn’t a week need to be 7.3826475 days long? Maybe add a leap day every two weeks, except every 8th, but do every 128th, skip every 5120th…
