Sperm Whales Sleep Vertically Using Bubbles | Sheffield News

Sperm whales just got a whole lot cooler—they sleep vertically, head-up just below the surface, using gas bubbles to control buoyancy and save energy. Discovered since 2008, they’re the only whales known to do this, staying near the surface to avoid rough waves. Scientists tracked them off Norway with special tags, catching bubble sounds and movement data that confirmed the theory: those bubbles help manage gas buildup from deep dives, letting them stay put while napping. It’s a wild, deep-sea adaptation that proves marine mammals live by totally different rules than us landlubbers. Listen in comfort:Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn.
