In our impression, the Arctic and the South Pole are both ice and snow, and the natural conditions are similar. Then why is there no penguin in the Arctic? In fact, a long time ago, the penguin survived in the Arctic, but it is now extinct.
The Arctic Big Penguin is 60 cm tall, with a brown head and black feathers on the back, which has reached several million. About 1000 years ago, the Vikings discovered the big penguins. After the 16th century, the Arctic expedition heats up. The big penguins were hunted and killed.
The penguins who live in the Antarctic today are the ancestors of the equator south of the equator. Because it couldn’t stand the equatorial currents and the higher temperatures, its ancestors did not choose to advance northward, but chose to live in the waters that flow from the cold waters of the Antarctic ice or the colder water that flows from the deep sea.
