Sperm whales use bubbles while resting, study reports
Sperm whales are the only whales known to rest vertically, floating steadily just below the ocean’s surface. Scientists had hypothesized that the animals release air bubbles to help maintain neutral buoyancy, and new research reportedly demonstrates how that process works while the whales rest.
Sperm whales are the only whales known to rest vertically, floating steadily just below the ocean’s surface, according to the supplied report.
Scientists had hypothesized that the whales release air bubbles to help them remain neutrally buoyant. The research is described as demonstrating the mechanism for the first time.
