Who is a penguin's favorite family member? Aunt Arctica! 

We kid! But seven of the 17 species of penguins can be found on the southernmost continent. Here are 20 more fun facts about these adorable tuxedoed birds. 

1. All 17 species of penguins are found exclusively in the Southern Hemisphere.

2. Emperor Penguins are the tallest species, standing nearly 4 feet tall. The smallest is the Little Blue Penguin, which is only about 16 inches.

3. The fastest species is the Gentoo Penguin, which can reach swimming speeds up to 22 mph.

4. A penguin's striking coloring is a matter of camouflage; from above, its black back blends into the murky depths of the ocean. From below, its white belly is hidden against the bright surface.

5. Fossils place the earliest penguin relative at some 60 million years ago, meaning an ancestor of the birds we see today survived the mass extinction of the dinosaurs.

6. Penguins ingest a lot of seawater while hunting for fish, but a special gland behind their eyes—the supraorbital gland—filters out the saltwater from their blood stream. Penguins excrete it through their beaks, or by sneezing.

7. Unlike most birds—which lose and replace a few feathers at a time—penguins molt all at once, spending two or three weeks land-bound as they undergo what is called the catastrophic molt.

8. All but two species of penguins breed in large colonies of up to one thousand birds.

9. It varies by species, but many penguins will mate with the same member of the opposite sex season after season.

10. Similarly, most species are also loyal to their exact nesting site, often returning to the same rookery in which they were born.

11. Some species create nests for their eggs out of pebbles and loose feathers. Emperor Penguins are an exception: They incubate a single egg each breeding season on the top of their feet. Under a loose fold of skin is a featherless area with a concentration of blood vessels that keeps the egg warm.

12. In some species, it is the male penguin which incubates the eggs while females leave to hunt for weeks at a time. Because of this, pudgy males—with enough fat storage to survive weeks without eating—are most desirable.

13. Penguin parents—both male and female—care for their young for several months until the chicks are strong enough to hunt for food on their own.

14. If a female Emperor Penguin's baby dies, she will often "kidnap" an unrelated chick.

15. Despite their lack of visible ears, penguins have excellent hearing and rely on distinct calls to identify their mates when returning to the crowded breeding grounds.

16. The first published account of penguins comes from Antonio Pigafetta, who was aboard Ferdinand Magellan's first circumnavigation of the globe in 1520. They spotted the animals near what was probably Punta Tombo in Argentina. (He called them "strange geese.")

17. An earlier, anonymous diary entry from Vasco da Gama's 1497 voyage around the Cape of Good Hope makes mention of flightless birds as large as ducks.

18. Because they aren't used to danger from animals on solid ground, wild penguins exhibit no particular fear of human tourists.

19. Unlike most sea mammals—which rely on blubber to stay warm—penguins survive because their feathers trap a layer of warm air next to the skin that serves as insulation, especially when they start generating muscular heat by swimming around.

20. In the 16th century, the word penguin actually referred to great auks (scientific name: Pinguinus impennis), a now-extinct species that inhabited the seas around eastern Canada. When explorers traveled to the Southern Hemisphere, they saw black and white birds that resembled auks, and called them penguins.

What’s Better Than a Dog in a Sweater? A Sweater That Shows an Image of Your Dog in a Sweater

If you think the sight of someone walking their sweater-clad dog is just about the cutest thing in the world, you’re absolutely correct. But what if that person was wearing a sweater that showed an image of their dog wearing a sweater? If you think that sounds even cuter, you’re in for a treat.

According to People, New York-based apparel company Sweater Hound will knit you a sweater that displays an image of your dog in a sweater—all you have to do is submit your favorite photo of your dog. And, because not all dogs love wearing sweaters in real life, your dog doesn’t have to be wearing a sweater in the photo you upload.

Each sweater is made from a combination of acrylic and recycled cotton, and will prove to your pet that you truly do love them more than anyone else (unless you already own sweaters emblazoned with the faces of your friends and family).

The sweaters, which cost $98 each, come in both child and adult sizes, and you can choose between cream, navy, black, and gray. The options don’t stop there—Sweater Hound offers sweaters that show your dog wearing just a bow tie, a bow tie and a sweater, a Santa hat and scarf, reindeer ears and a sweater, or even a “Super Dog” cape and domino mask outfit.

If sweaters aren’t really your style, there are also hoodies and sweatpants decorated with a smaller, logo-sized image of your dog. Or, you could snuggle with your prized pooch underneath a warm blanket bearing a rather giant image of said pooch.

While the company does specialize in creating dog-related products, they’ll do their best to accommodate people who love salamanders in Santa hats, birds in bow ties, and other pets wearing clothes. You can email them at Hello@Sweaterhound.com to discuss your options.

If you’re hoping to get someone a gift from Sweater Hound this holiday season, you should act fast: You have to place your order by December 4 in order to guarantee delivery before Christmas, and that date will likely change as the days go by.

Adorable, customizable clothing is just one of the many perks of being a dog owner—here are 10 more scientifically proven benefits.

Move Over Dogs, Goats, and Peacocks: Llamas Are the Hot New Therapy Animal

Possibly because Dasher, Dancer, Prancer, and the rest of the reindeer are pretty busy at this time of year, Kimpton Hotel Monaco in Portland, Oregon, is offering guests the chance to hang out with a few jolly llamas instead.

The Washington Post reports that the friendly, festively dressed llamas belong to Mountain Peaks Therapy Llamas and Alpacas, which usually brings them to hospitals, rehabilitation centers, senior communities, hospice care, special-needs organizations, and even schools. According to the organization’s website, the visits help “alleviate loneliness, lower blood pressure, and reduce stress.”

And, though the clinical benefits to the Kimpton’s guests haven’t been proven, hotel manager Travis Williams confirms that everyone definitely loves spending time with the quirky quadrupeds. Last year, after overwhelmingly positive reactions to the llama visits, the hotel decided to bring them back.

“Once we saw the joy that it brought people, we just kept going,” Williams told The Washington Post.

While it might seem like the use of llamas for therapy is a characteristically Portland-ish idea, it’s not the only place you can find them. The New York Times reports that 20 llamas and alpacas are registered with Pet Partners, a national nonprofit organization for therapy animals, and many others are owned and trained by private family farms across the country.

Jeff and Carol Rutledge, for example, have 13 llamas and alpacas on their property in Stockdale, Texas, outside San Antonio. Three of them are registered therapy animals, having passed a test that includes being touched by strangers and staying unaffected while people argue near them.

During their visits to assisted living facilities, veterans’ homes, and other events in the area, the Rutledges have observed the animals having a profound effect on residents’ behavior. One man, who is nonverbal and recovering from a motorcycle accident, will murmur as he grooms one of the llamas. And the Rutledges’ high-school-aged daughter, Zoe, even did a science experiment for her 4-H club that showed the residents’ blood pressure is lower after visiting with the llamas.

While there’s not a very high chance of seeing therapy llamas in airports just yet, you might be lucky enough to see something a little smaller—like LiLou, San Francisco International Airport’s first therapy pig.
