Whales Rest Upside Down for Energy | Science News

Southern right whales are doing something wild—chilling upside down—and scientists think moms are doing it to save energy and call the shots on feeding. Using drones, researchers tracked mom-calf pairs off South Australia for 75 hours, finding moms spent 33% of their time resting, often floating on their backs or flipping over (just 2% of the time). This rare move lets moms control when calves get milk and might help them cool off. Why some moms do it and others don’t? Maybe it’s learned from moms or peers. A fascinating glimpse into whale parenting and survival. Listen in comfort:Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn.
