"the little penguin is so arrogant, Ali Ali, wearing that black dress with a white belly", this children's song is a very vivid introduction to the appearance of penguins, which was the first time I knew about penguins when I was a child. Later, I saw real penguins on TV. They are very cute, waddling and always in groups. Let's take a look at what kind of animal penguins are. What kind of food do you usually eat?

What kind of animals are penguins?

Penguins are marine birds, and like the ostriches we are familiar with, they are flightless birds. However, according to Xanguan data, penguins used to fly. In order to adapt to life in the ocean, their wings slowly degenerated into swimming flippers, which is what penguins we see today.

Why are penguins birds? We know that birds are egg-laying vertebrates, which have feathers and can be divided into three categories:

First, birds that can walk but can't fly, similar to ostriches.

Second, it can swim and dive, but it can't fly, just like penguins.

Third, there are developed wings that can fly freely in the sky, that is, the common flying birds, swallows, sparrows and so on.

Penguin is a very typical seabird. it can swim at a height that other birds cannot reach. Because many waterbirds swim and dive by rowing in the water with very long flippers. Although the penguin also has this kind of web, it only plays the role of controlling the direction, as long as it relies on its wings when rowing in the water, so that it can constantly swim in the water.

What kind of food do penguins usually eat?

Penguins feed mainly on plankton in the ocean, such as Antarctic krill. Of course, they also prey on small fish, squid and wrist creatures.

Penguins have a very good appetite, penguins can eat almost one and a half jin of food, they are also good helpers to maintain the food chain in the ocean. Antarctic krill are basically preyed on by penguins, accounting for a large part of whales' prey on krill.

It is understood that penguins are very old swimming birds, and they were found in Antarctica before the ice armor was put on. Antarctica has more land and a wide sea level, and their eyes have very flat corneas, so they can see things under the water clearly. Their eyes can transmit the influence to the brain and can be used as a telescope integration to make it have a farsighted effect. Although penguins have no teeth, it does not prevent them from eating food, because penguins have barbs on their tongues and upper jaws and can play their role in swallowing food.

The above is the answer to what kind of animal penguin is and what food it usually eats. I hope it will be helpful to you.
