Documenting the World’s Animals, One Picture at a Time

For years National Geographic photographer Joel Sartore worked far away from home—documenting the astonishing wildlife of Bolivia’s Madidi National Park or scrambling up the three tallest peaks in Great Britain or getting too close to grizzly bears in Alaska. His wife, Kathy, stayed in Lincoln, Nebraska, and took care of the kids. “He never wanted to change diapers or be a stay-at-home dad,” she says.

You aren't alone in your nightly tossing and turning. Sea lions do it, too.  A new video by National Geographic details the strange ways different animals sleep. Walruses, for example, can sleep floating vertically in the water, their heads bobbing above the waves. When hippos sleep in water, some sleep under the water, occasionally popping up to take a breath.  The most disturbingly odd sleeping style in the animal kingdom is, of course, the human grandfather.

Emperor Penguin Photos Documented In National Geographic Magazine

When an emperor penguin swims through the water, it is slowed by the friction between its body and the water, keeping its maximum speed somewhere between four and nine feet a second. But in short bursts the penguin can double or even triple its speed by releasing air from its feathers in the form of tiny bubbles. These reduce the density and viscosity of the water around the penguin’s body, cutting drag and enabling the bird to reach speeds that would otherwise be impossible.
