15 Weird Penguin Facts That Will Make You Love Them Even More

Tuxedos, pebble proposals and naps that last four seconds.

Penguins can't fly, they walk like they're late for a meeting, and somehow they're one of the most fascinating birds on the planet. Here are 15 real penguin facts that sound totally made up.

1.Almost all penguins live south of the equator

Sorry, North Pole: no penguins. The Galápagos penguin is the one species that sometimes ventures just north of the equator.

2.The biggest penguin is nearly 4 feet tall

Emperor penguins can stand about 45 inches tall and are the largest penguins alive today. Basically a first-grader in a tuxedo.

3.The smallest is about a foot tall

Little penguins, sometimes called fairy penguins, live in Australia and New Zealand and stand only around 12 to 13 inches tall.

4.Emperor penguin dads babysit the egg on their feet

After the mom lays the egg, the dad balances it on his feet under a warm flap of skin for about two months in the Antarctic winter, without eating. Dad of the year, every year.

5.They take turns in the warm spot

To survive brutal cold, emperor penguins pack together in huge huddles and slowly shuffle, so birds on the chilly outside edge eventually get a turn in the cozy middle.

6.Gentoo penguins are seriously fast

Gentoos are often called the fastest-swimming birds, with speeds commonly reported at around 22 mph underwater. They're clumsy on land, but in the water they're rockets.

7.They can drink seawater

A special gland above their eyes filters extra salt out of their blood. The salty liquid drips out through the bill, and penguins shake or sneeze it away.

8.Some penguins propose with a pebble

In species like Adélie and gentoo penguins, nests are built from stones, and males bring pebbles to their partners. Pebbles are so valuable that some penguins steal them from the neighbors.

9.The tuxedo is camouflage

From above, a penguin's dark back blends in with the deep water. From below, its white belly blends in with the bright surface. It's called countershading, and it helps them hide from predators and sneak up on prey.

10.Emperor penguins are deep-diving champions

They can dive more than 1,500 feet below the surface and hold their breath for over 20 minutes. Most of us can barely manage the deep end of the pool.

11.They lose all their feathers at once

Once a year, penguins go through a big molt and replace their feathers all at the same time. They aren't waterproof during it, so they stay on land and can't go fishing until it's over.

12.They leap out of the water like dolphins

Some penguins "porpoise," jumping out of the water as they swim so they can grab a breath without slowing down.

13.Ancient penguins were giants

Fossils show some penguins that lived tens of millions of years ago were way bigger than today's. One species found in New Zealand is estimated to have weighed around 340 pounds.

14.Chinstrap penguins nap in four-second bursts

Scientists found that nesting chinstrap penguins take more than 10,000 tiny "microsleeps" a day, each lasting about four seconds on average. It adds up to hours of sleep while still guarding their eggs.

15.They can find their partner by voice

In a noisy colony of thousands of birds that look almost exactly alike, penguins recognize their mates and chicks by their unique calls.
