Penguins don’t soar through the air, but they fly into our hearts with their endearing awkwardness and remarkable adaptations.

This set of 15 cute, true penguin facts will have you grinning, astounded, and perhaps a little bit in love with these waddling wonders.
1. Penguins Ask for Hands in Pebbles

Adélie and Gentoo penguins are accustomed to wooing their partners by presenting them with the most refined pebble they can discover. When the female penguin agrees to the pebble, they put it together in their nest—nature’s most adorable engagement! These pebbles are treasured, and some sneaky penguins even pilfer them from neighboring penguins.
2. Emperor Penguin Fathers Are the Best Babysitters

Once the female has laid her egg, she departs to feed for two months, while the male incubates the egg. He rests it on his feet, folds it into his brood pouch, and suffers freezing gusts of -60°C. For the entire duration, he does not eat at all—typical fatherly commitment!
3. Penguins Have Built-In Sunglasses

Penguins possess a unique gland near the back of their eyes that removes excess salt, allowing them to cope with saltwater. Their eyes are also specialized to view the underwater world clearly and cope with bright glints of snow—it’s as if they have a built-in pair of polarized sunglasses!
4. Penguins “Fly” Underwater

Although they cannot fly in the air, penguins are remarkable swimmers, employing their flippers as wings. They’re capable of zooming through water at speeds of up to 22 mph (35 km/h), particularly when porpoising—jumping in and out like dolphins. It’s an underwater ballet that’s both strong and elegant.
5. Some Penguins Have Pink “Eyebrows”

The Northern Rockhopper penguin wears flashy, crazy yellow and pink tufts of feathers above its eyes, giving it a permanently surprised expression. It deploys these fancy feathers in courtship routines and to establish dominance. They’re the penguin equivalent of punk rockers.
6. Penguins Are Hopeless Romantics

Most penguin species, such as the Macaroni and Royal penguins, are monogamous and mate with the same partner every year. They know each other by distinctive vocalizations, such as individual love songs. Their reunion dances are swoon-inducing ceremonies of flippers flapping and soft preening.
7. Penguins Waddle for Efficiency

That adorable, clumsy waddle actually saves energy, up to 80% more efficient than walking around in snow normally. Their side-to-side gait stores and releases energy with every step. It’s cute and functional!
8. Baby Penguins Have Fuzzy Coats Called “Down”

Chicks emerge covered in soft, fuzzy gray or brown feathers that provide insulation until waterproof adult feathers develop. During this period, they remain in a crèche (group) for protection as the parents go hunting. They resemble walking fluffballs with beaks!
9. Penguins Sing Duets

Penguin parents sometimes have special calls to recognize each other among thousands of colony members when it is loud. For Emperor penguins, the duo does a duet to strengthen their relationship. These are very complex vocalizations—essentially singing penguin opera!
10. They Can Drink Seawater

Penguins can filter out salt from the sea they inhabit, thanks to a special supraorbital gland. They kick out excess salt through their beaks or sneeze it out—cute, dramatic sneezes, at that! This helps them survive where fresh water is not available.
11. Penguins Enjoy Sliding

When they travel over ice, penguins frequently toboggan belly down and propel themselves with flippers and feet. This is quicker, enjoyable, and energy-conserving for extended walks to the sea. Visualize an army of little sledders gliding over Antarctica—it’s a blast.
12. They Have Built-In Tuxedos

Penguins’ tuxedo-like black-and-white plumage is not only stylish—it’s survival gear. Their dark backs match the ocean depths from above, and their white bellies blend with the light surface from below. Nature provided both style and functionality!
13. Some Penguins Live in Warm Climates

Not every penguin is an Antarctic bird—Galápagos penguins inhabit the equator! They adapt to hot weather by panting, stretching out their flippers, and resting in shaded crevices. Yes, there are tropical penguins basking in the sun, too.
14. Penguins Are Expert Divers

Emperor penguins dive more than 1,800 feet (550 meters) deep and hold their breath longer than 20 minutes. Their bodies hold oxygen in muscles, not blood, and they decrease their heart rate to save energy. They are essentially feathered submarines.
15. Penguins Create “Penguin Highways”

As time passes, penguins wear out pathways in the snow as they move between the ocean and their breeding grounds. These routes, referred to as “penguin highways,” are so heavily traveled they resemble small roads! Seeing a line of determined waddlers on their daily commute is as adorable as it gets.
