Sperm whales release bubbles to sleep floating vertically, scientists find

Scientists have discovered that sperm whales sleep while floating vertically in the water by releasing gas bubbles that help regulate their buoyancy. This fascinating adaptation allows them to rest without expending energy to stay afloat. This finding provides insight into the complex behaviors of these deep-sea giants and highlights the unique strategies marine mammals use to survive in their environment. Understanding such behaviors can enhance our knowledge of marine ecosystems and the adaptability of different species.
