In a study in the journal Science, McKnight and his colleagues report they may have found the answer: Seals can directly perceive how much oxygen is circulating in their body and act accordingly. It's ...

Seals store oxygen efficiently as well as possess a unique cognitive ability to sense blood oxygen levels. This helps them dive longer and avoid drowning. “The study provides compelling evidence ...

A new study from researchers at the University of St. Andrews’s Sea Mammal Research Unit in Scotland suggests that some seals can cognitively perceive their blood oxygen supply and plan their diving ...

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

As this video proves, encounters with seals while diving are not uncommon. We’re sure this diver didn’t expect so much affection, but the big question is this: Are all seals this loving toward ...

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.

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 ...

Marine mammals can dive for remarkably long periods because their bodies have evolved to adapt to the underwater environment. Elephant seals, in particular, can hold their breath for about two hours.
