What animals live in the Arctic?

Arctic animals include: polar bear, grizzly bear, Arctic fox, Arctic wolf, Arctic hare, beluga, narwhal, seal, walrus, Arctic water sloth, Arctic owl, puffin, Arctic grouse , Arctic falcon, Arctic bald eagle, grayling, gray trout, herring, smelt, long body cod, etc.

The animals that live in the Arctic mainly include animals that live in the Arctic tundra zone and marine animals in the Arctic Ocean. Among them are whales and polar bears. Due to the rise in global temperatures, the ice floes in the Arctic have gradually begun to melt. The former home of polar bears has been damaged to a certain extent. They are likely to become extinct in the near future and require human protection.

The Arctic tundra is a vast frozen swamp zone between the Arctic Ocean coast and the Taiga, with a total area of ??13 million square kilometers. Its biggest feature is that it has a very thick layer of permafrost, up to 488 meters thick, and the thickest can be more than 600 meters. Therefore, the Arctic tundra can also be collectively referred to as the tundra along with the plateau tundra in other parts of the world.

The tundra climate is a desert climate, with annual precipitation of only 200 mm, which is similar to arid areas such as the Loess Plateau in my country. But if you take a plane over the tundra in the summer, you will be surprised to find that the tundra area is intertwined with water networks, densely covered with lakes and swamps, and the water area appears to be far more than the land area. Waterbirds are playing on the water, and flowers are blooming on the land, just like a landscape of a water country. This is mainly due to low temperatures and slow evaporation of water. And there is permafrost a few centimeters below the surface, which prevents normal leakage and drainage. By winter, the entire tundra is covered in ice and snow, making it desolate. Plants on the southern boundary of the tundra have a growing period of about 90 days per year, while those on the northern boundary only grow for 20 days. Further north, lichens on islands in the hinterland of the Arctic Ocean can only grow for 1 to 2 days per year, or not at all.
