20 Interesting Penguin Facts: You Didn’t Know

Penguins are mainly a group of aquatic, flightless birds which live mostly in the Southern Hemisphere. These birds belong to the family of Spheniscidae. These dark and white colored animals are highly adapted for life in the water. 

These birds are speedy swimmers and also very cute animals as well. Also, these creatures live in some of the harshest and coldest environments on Earth. These birds have unique adaptations that let them survive in various extreme conditions. 

There are many fascinating facts that you can learn about this bird. So, in this article, we will explore some interesting and amazing facts about these unique birds, known as penguins.

Facts About Penguins

There are at least 17 penguins species:

According to scientists, there are mainly between 17 and 20 species of penguin birds. You can see these flightless birds everywhere, from Australia to Africa. Crested penguins, like the macaroni and rockhopper species, live in the sub-Antarctic region and also the Antarctic Peninsula.

However, the less-feathery and temperate penguins known as Humboldt and Magellanic species are native animals to South America. Only one species lives above the southern hemisphere, which is called the Galapagos penguin.

The smallest and largest ones:

The smallest penguin species are the Little Blue Penguins or the fairy penguins. These cute species of penguins can be 13 to 15 inches in height. Also, this penguin species does not weigh more than just 3 pounds.

In contrast, the largest penguin is the Emperor Penguin, which can grow up to 4 feet tall and weigh 90 pounds.

They have a thick layer of insulation.

Penguins have a very thick layer of insulating feathers that assist them in remaining warm and comfortable even in the harsh climate of the Antarctic region. These feathers are densely packed and even overlapping.

Moreover, these feathers are coated in a special oil that can make them waterproof. This certain kind of oil is produced by a particular gland located near the base of the penguin’s tail, and the bird spreads it over its feather with the help of its beak.

They are flightless birds:

Penguins are flightless birds, and their wings have evolved into soft flippers that are perfect for swimming in the water. These flightless birds are some of the best swimmers in the animal kingdom.

Some of them can even swim up to 22 miles per hour. These adorable birds use their flippers to ‘fly’ through the water. After that, they streamlined their webbed feet and bodies, which helped them to navigate quickly and efficiently.

They have short legs:

When penguins are on land, they must waddle awkwardly due to their heavy bodies and short legs. However, these birds are graceful and agile swimmers in the water. They use their flippers to steer properly and their feet to propel themselves through the cold water.

There was once a mega penguin:

In the year 2014, scientists discovered the 37-million-year-old remains of a ‘mega’ species of penguin on Seymour Island, Antarctic Peninsula. Based on the remains, researchers estimated that the massive penguin was 6.5 feet tall and more than 250 pounds in weight.

Penguins are social birds:

Penguins are social animals that live in large colonies, sometimes the number reaching the millions. These cute animals use a variety of vocalizations to communicate with each other.

Their vocalizations include braying sounds, trumpeting calls, and honks. These fascinating birds communicate through body languages, such as preening and bowing.

Penguins are monogamous:

Penguins are monogamous, meaning many species mate for life. They have complex courtship rituals involving different vocalizations, affection displays, and gifts of twigs and tones. The male penguin will often look for the pebble to give to his mate, which they will use to build their nest.

The male penguin takes care of the chicks:

Once the egg hatches, the male Emperor Penguin continues to care for the chick, while the female one returns to help with feeding. 

The male penguin will keep the chick warm by holding it on his feet and covering it with his belly feathers. He will also regurgitate food for the chick to eat.

They are unique parents:

Emperor Penguins are famous for their unique parenting strategies. After the female penguin lays her egg, she immediately transfers it to the male, who carries it on his feet and then covers it with a fold of skin to keep it warm. 

The female then returns to the sea to feed while the male remains on the ice to incubate the egg. He will not eat up for up to two months while he waits for the egg to hatch.

Penguins are excellent divers:

Penguins are expert divers, and some species of this flightless bird can dive to depths of up to 1800 feet. They can hold their breath for almost 20 minutes while searching for food, mainly krill and fish.

Some small-sized penguins can launch themselves almost 6 to 9 feet into the air by speedily swimming to the surface and bursting over the solid ice to make the leap back ashore.

Gentoos, the speediest of penguins, can swim at a speed of 10 to 20 miles per hour.

They have a special gland:

Penguins have a special gland that is located above their eyes that filters out excess salt from their bloodstream. They excrete this saltwater through their beaks, which can often give them a sneezy appearance.

They can stay warm in winter:

Penguins have a thick layer of blubber that aids them in conserving heat and also stay warm in cold temperatures. This layer of fat can even help them to stay buoyant in the water, which makes it a lot easier for them to swim.

The secret of their name:

The name “penguin” actually comes from the Welsh words “pen gwyn,” which means “white head.” This unique name was originally used to describe the Great Auk, a flightless bird that was hunted to extinction in the 19th century.

Some of them have unique adaptations:

Some penguins have unique adaptations that enable them to survive in particular environments. For example, Adelie Penguin has a special kind of gland above its eye that creates a fluid that can help them to remove salt from its feathers. 

This adaptation lets the Adelie live in areas where freshwater is scarce.

They are not afraid of humans:

Penguins are cute birds that are not afraid of humans and will sometimes approach them out of curiosity. However, it is crucial to remember that they are mainly wild animals and must not be approached or even touched.

In some areas, penguin encounters can be arranged through various eco-tourism companies that work under strict guidelines to protect the animals.

Their suits work as a perfect camouflage:

The black backs blend with the ocean water when watched from above. Also, the white-colored bellies of these animals match the bright surface when seen from below.

This disguises them from their predators, such as leopard seals, and helps them to catch prey, such as squid, fish, krill, and crabs.

The penguin fossil:

The oldest known penguin fossil is almost 60 million years old and was found in Antarctica. This shows that penguins have lived in the Southern Hemisphere for a long time.

Penguins are not the only flightless birds, as there are many other flightless birds, such as emu, kiwi, ostrich, etc. However, penguins are the only flightless birds that are adapted for life in the water.

They are threatened:

Many penguins are threatened by climate change, which is causing the ice in their habitats to melt. This reduces the amount of food available to them and makes it much harder for them to survive and breed.

Other threats are pollution, overfishing, and habitat destruction. There are many underway conservation efforts to protect the population of penguins. Some of those efforts include reducing greenhouse gas emissions, marine protected areas, etc. 

Penguins can become airborne:

Though penguins cannot fly, they can leap really high. Leaping in the air lets them escape the clutches of several predators, like orcas and leopard seals. Penguins depend on air bubbles while leaping.

They warp those air bubbles around their bodies and then propel themselves above the water like torpedoes and ships. The pint-sized Adele penguins can leap up to nine feet in the air.

So, penguins are fascinating birds with a variety of unique adaptations. Hence, at the end of this article, we learned about 20 amazing facts about penguins. These facts offer us a clear picture of this adorable bird in our ecosystem. To know more, you can see our website.
