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.
