When sperm whales need a nap, they take a deep breath, dive down about 45 feet and arrange themselves into perfectly-level, vertical patterns. They sleep sound and still for up to two hours at a time between breaths, in pods of 5 or 6 whales, presumably for protection. No one knew whales slept vertically until a 2008 study documented the behavior. And no one captured really good photography of it in the wild until 2017.

@globalmuseum Saw someone else once comment that if medieval monks saw this they'd either levitate in ecstasy, or draw an incomprehensible picture of this in the margins of The Gospels while saying something like "The Lord maketh the Leviathan to gaze upon Heaven from whense their salvation came."
