How do penguins spend the winter?

Penguins are born in the winter. Penguins can live and breed in the cold of-60 ℃. Of course, after the Antarctic winter, companions will huddle together to keep warm.

The penguin, known as the "boat of the ocean", is one of the oldest swimming birds. Mainly living in the southern hemisphere, belonging to the order Penguin, Penguinidae. The characteristic is that you can't fly.

Penguins reproduce by laying eggs. The breeding cycle of the same species of penguins is also related to latitude. Some species migrate long distances to ancestral nests inland to lay eggs. Spotted-billed penguins and small blue penguins breed twice a year, while most species reproduce only once a year. King penguins breed twice in three years. Most penguins breed in spring and summer in the southern hemisphere.

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.
