There are 18 species of penguins in the world, most of which are distributed and live in the southern hemisphere. On land, it looks like a gentleman in a tuxedo, walking and rocking.

But in the water, the penguin's short wings become a pair of powerful "paddles."

Penguins are not the short legs we imagined. The researchers found that their legs were hidden under thick layers of fat. The legs are about the same length as the body.

Here are some interesting facts about penguins.

Penguins can't fly.

Despite their beauty and the fact that they are birds, these creatures cannot fly.

They are excellent swimmers and divers. Their feet and body shape make it easier for them to swim underwater. This also makes them wobbly on land.

Sleep at sea.

Penguins usually take a short nap in the water, which could also be explained by predators wandering around corners in search of food, allowing penguins to survive on the ice.

Use sign language.

Penguins actually communicate with each other in sign language. This can be seen when they wave their flippers and head movements to communicate with the penguins.

The habits of penguins.

1. Food.

Each penguin consumes an average of 0.75kg of food per day, mainly Antarctic krill. Therefore, penguins play an important role as predators in the Southern Ocean food chain.

2. Character.

Penguins are friendly to humans and are very cute little animals. When someone approaches, it will not run away directly, but is very curious.

3. Sleep time.

If there is light 24 hours a day and the temperature is around 0.8 degrees, the 24-hour sleep time of emperor penguins accounts for 45.1%. There are also special cases.

4. Swimming.

Penguins are birds, but they don't fly. They swim very well, and penguins have webbed feet, but they only act as rudders to steer. The power to move forward is entirely dependent on the paddle-like wings.

Penguins often swim in dolphin style, that is, snorkeling for a certain distance, and after breathing out of the water, dive down to continue swimming.

It is considered the most hardy bird in the world.

Penguins are known as "boats of the ocean" and are one of the oldest swimming birds. They may have settled in Antarctica long before Earth donned its ice armor.

They can survive and reproduce in the freezing cold of -40°C.
