5 Things You (Probably) Didn’t Know About Penguins

We all know penguins are adorable, waddling wonders of the Southern Hemisphere — but there’s far more to these tuxedoed charmers than meets the eye. Beyond the myths and beyond the fluff, penguins are fascinating, resilient, and, at times, downright surprising.

Here are 5 things you probably didn’t know about penguins — and no, none of them involve dancing or happy feet.

1. Penguins Have Knees — Seriously

It’s hard to believe when you see them waddle, but penguins do have knees. Their legs are tucked so close to their bodies, and hidden beneath feathers and blubber, that they appear stumpy. But beneath it all is a fully articulated knee joint. Their comical walk isn’t due to a lack of flexibility — it’s just biomechanical efficiency in icy terrain.

2. Some Penguins Are Surprisingly Loud

Penguins don’t just make cute squawking sounds — they have full-on vocal identities. Each penguin has a unique call, which is how mates and chicks recognize one another in noisy colonies of thousands. Emperor penguins use deep trumpeting tones, while others, like the Adélie, sound almost like high-pitched braying. It’s like a penguin opera out there.

3. Penguins Can Drink Saltwater

Unlike humans, penguins don’t need fresh water to survive. Thanks to a special gland above their eyes, they can filter out the salt from seawater. This means they can dive, feed, and hydrate all from the ocean — no snow cones required.

4. They Can Leap Like Olympians

You’d never guess it from the way they move on land, but penguins are seriously athletic underwater. Some species, like the Adélie, can leap up to 2 metres (over 6 feet) out of the water when returning to ice. It’s called “porpoising,” and it’s both adorable and impressive — like an avian Cirque du Soleil.

5. Penguins “Propose” with Pebbles

Yes, it’s true — many penguins are romantics at heart. During mating season, species like the Gentoo present carefully selected pebbles to potential mates. If the recipient accepts, the pebble becomes part of their nest. If not… back to the dating pool. It’s like the penguin version of a shiny engagement ring, but colder and way more charming.

Penguins are full of surprises — just like Antarctica itself. At Vintage Antarctica, our Penguin Collection celebrates not just the cute, but the clever and courageous spirit of these iconic birds.
