ScienceBlowing bubbles may help resting sperm whales stay submerged
Scientists think sperm whales may use bubbles to remain suspended beneath the ocean surface while resting. Their massive heads contain oil, wax and air, features that might otherwise make them drift upward. By releasing bubbles, the whales may counter that tendency and remain underwater. The finding offers a possible explanation for how they rest below the surface.
