The sea mammals may actually be able to sense the amount of oxygen in their blood—something we humans can't do. A new study suggests gray seals (Halichoerus grypus) can sense the level of oxygen in ...

Diving is physiologically challenging for marine animals. Long and deep dives can trigger "anaerobic" (oxygen-less) metabolism in organs other than the heart and brain that causes lactic acid to ...

ITHACA, N.Y. -- New research in biomechanics measures the impact of head-first, hand-first and feet-first diving and the likelihood of injury at different diving heights, providing data-driven ...

Spending hours underwater reveals details most divers never notice. Long underwater diving sessions push limits on focus, air management, and physical endurance. As time passes, marine life behavior ...
