How do animals sleep? For this group of 30-some sperm whales 50 feet below the surface of the Indian Ocean, sleep looks spooky. These female adult whales can stay like this, without moving, for hours. Dolphins can shut off half their brains. Elephants snooze only two hours a night. Liz Langley explores why animals have such different ways of getting shut-eye.
What we could learn from chimps: The moms dote. The sons show affection back. For decades. “About a third of adult males are essentially best friends with their mothers,” Harvard’s Rachna Reddy, co-author of a new study on chimpanzee motherhood, tells Nat Geo. See these photos of moments between animal mothers and babies.
Are city squirrels bolder? That may be the wrong question, researchers say. It’s true that some squirrels have become more accustomed to humans, but studies have shown that their willingness to respond to all threats had not lessened, Discover magazine reports.
A horse, leading others to water: Credit wild horses and donkeys with helping other species in the U.S. southwest. New research from the Mojave Desert shows the animals dig down six inches or more to create “mini-oases” to quench their thirst—and that of 50-some other types of animals. Nat Geo’s Douglas Main employed that tactic himself in an Arizona desert when he was drenched with a foul-smelling chemical from a shimmery green beetle. “Too far removed from any faucet, I had to improvise. So I dug into the dry riverbed about a foot, until I hit water, and was able to wash the scent away,” Main wrote in this story.
All ants aren’t alike: Photographer Eduard Florin Niga shows (and tells) the bountiful variety of ants throughout the world—through images of their heads. Among the species collected in a new book is the giant turtle ant, Cephalotes atratus, sometimes called “the Darth Vader of the ant world.” We’ll have more on this effort in our Photography newsletter on Saturday, but for now, see the photos!
