In a study in the journal Science, McKnight and his colleagues report they may have found the answer: Seals can directly ...

The sea mammals may actually be able to sense the amount of oxygen in their blood—something we humans can't do.

As seals dive more frequently—and for longer—than humans do, the range of carbon dioxide in their bodies varies more widely.

Scientists at the University of St. Andrews found that seals can detect blood oxygen levels, allowing them to plan dives and ...

Chris McKnight has spent much of his career studying the physiology of seals. But in 2019, the ecologist decided to test a new instrument for gathering data underwater on another kind of swimming ...

That's exactly what the researchers found. In contrast, the seals didn't really change their diving behavior in response to CO2, even when it was 200 times ambient levels. That was "a real ...

Monterey, California, is home to insatiably curious and playful harbor seals. Here's what it's like when they're zipping ...

What do elite Navy SEALS, world-class free-divers, and marine mammals have in common? They all push the limits of breath-hold ...

The seals’ ability to detect the amount of oxygen in their blood may help them make diving decisions and avoid drowning.
