For diving mammals, avoiding drowning is critical to survival. Even though diving mammals have adaptations to store ...

Unlike humans, marine mammals have evolved remarkable adaptations that allow them to hold their breath for extended periods, ...

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

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.

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

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

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

Gray seals may possess a secret sense that helps them survive at sea. The marine mammals adjusted their time spent underwater based on the amount of oxygen in the air they breathed before diving ...

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 ...
