Why are there no penguins in the Arctic? Why is there no bear in Antarctica?

Why only polar bears don't have Antarctic bears? And there are no penguins in the Arctic? I think many people don't know the answer to this question. Today, let's make it popular for you.

Why there are no penguins in the Arctic

Paleontological research shows that penguins have appeared in the Tertiary period as early as 50 million years ago, and it has been found that penguins have lived in the Arctic, because an extinct bird skeleton has been found in the Arctic region, known as the 'great Penguin'.

This' big Penguin 'has a body height of about 60 cm, a brown head, black back feathers and a white belly. They are as clumsy as other penguins when they walk on land, but they are also good at swimming in the sea. Penguins are mainly distributed in Scandinavia in Europe, Asia and North America, as well as some islands in the Arctic Ocean. However, three or four hundred years ago, Europe set off a wave of exploration to the Arctic. With the arrival of explorers and immigrants, the number of 'big penguins' has declined dramatically. When the last' big Penguin 'is killed, there will be no penguins in the northern hemisphere. That's why there are no penguins in the Arctic.

Why there are no bears in Antarctica

Antarctica was a continent surrounded by oceans long before the ancestors of bears appeared, not connected with other continents. The partition of the ocean makes it impossible for terrestrial bears to move there, so it is impossible to find polar bears in the Antarctic. In this 14 million square kilometer continent, there are no animals of continental fauna, all of which are classified as marine fauna
