Wissenschaftler entdecken, dass Pottwale beim vertikalen Schweben Blasen freisetzen, um den Auftrieb und den Schlaf zu regulieren

„The tags, which record sound and 3D animal movements, captured clear bubble sounds, while animal movement data was used to create a simulation taking in tissue density, drag through the water and gas volumes in the animals‘ bodies.
The simulation confirmed that the release of bubbles reduced the whales‘ positive buoyancy, enabling them to remain submerged while resting.“
