Today the Department of Awesome Natural Phenomena shares a rare and incredible sight: a pod of sperm whales fast asleep, floating in a vertical position, some with noses pointed up towards the water’s surface, some pointed down to the ocean floor. It’s a haunting sight, something the whales are believed to do for only brief periods of about 12 minutes at a time. Quick, vertical power naps.
Researchers have observed sleeping sperm whales exhibiting the same sort of Rapid Eye Movement that’s associated with dreaming in humans. So now we’re wondering what sorts of awesome things whales dream about.
