Penguins are the North Pole of Antarctica.

There are no penguins in the Antarctic and Arctic!

The climate in the North Pole and the South Pole is equally cold and snowy. Why are there no penguins in the Arctic? In fact, a long time ago, the "Arctic Penguin" once lived in the Arctic, but now it is extinct.

"Arctic Penguin" is a gentleman with a height of 60 cm, a brown head and black back feathers. They lived in Scandinavia, Canada, what is now northern Russia, and all the Arctic and subarctic islands, and their number once reached several million.

About 1000 years ago, the vikings discovered giant penguins. From then on, the bad luck of the big penguin came. Especially after the16th century, the arctic exploration fever rose, and giant penguins became the hunting targets of explorers, navigators and aborigines. Long-term hunting and indiscriminate killing led to the extinction of the giant penguins in the Arctic.

The ancestors of penguins living in the Antarctic today developed in areas south of the equator. Scientists speculate that the reason why they don't continue to push north to the northern hemisphere may be that penguins can't stand warm tropical waters. The northernmost boundary of their distribution range is very consistent with the area where the annual average temperature is 20℃. The equatorial warm current and high temperature form a natural barrier, which prevents penguins from crossing the equator to the north. They can only live in the waters where Antarctic ice and snow melt water or colder water in the deep sea passes.
