Footage has surfaced online showing seals sleeping underwater in shallow water. The animals sink to the seabed, fall asleep, and drift.
When sleeping underwater, seals float like logs. This occurs in shallow areas: they descend to the bottom and drift without waking up. This is made possible by unihemispheric sleep.
When a seal runs out of air, it swims to the surface—barely waking up—takes a few deep breaths, closes its nostrils, and dives back down. A level of tranquility worth aspiring to.
