π³ Sperm whales use bubbles to stay underwater
Scientists discovered that sperm whales use bubble releases to manage their buoyancy while resting beneath the ocean surface. This behavior was observed in sperm whales off the coast of Norway. The study tracked them using tags and found bubbles counter the natural tendency to float due to spermaceti oil. This action helps them remain almost weightless in the water, counteracting gas expansion. Future research will explore if this release is conscious and if they sleep with one brain half at a time.
