Study Finds grey Seals Can Track Blood Oxygen to Prevent Drowning

A study has revealed that grey seals can monitor their blood oxygen levels to determine when they need to surface for air. Researchers tested seals in controlled environments, exposing them to different oxygen and carbon dioxide levels. The findings confirmed that higher oxygen led to longer dives, while reduced oxygen shortened them. Surprisingly, increased carbon dioxide had no effect on dive times. Experts believe this discovery provides new insights into marine mammal physiology and could help understand how deep-diving species regulate their breathing.
