Antarctica is primarily an ice sheet and does not support Tundra vegetation in the same way as the northern circumpolar regions.

At higher altitudes in the Himalayas, the climate becomes cold enough to support coniferous forests, which are characteristic of the Taiga biome.

Tundra vegetation is found in the northern parts of Asia, Europe, and North America, but it is not a characteristic biome of South America.

The Tundra biome is characterized by a short growing season and cold temperatures, which limit vegetation to low-growing plants like mosses, lichens, and small shrubs.

Seals and walruses are marine mammals adapted to the cold, icy waters associated with the Tundra and polar regions.

Musk-oxen and snow foxes are animals adapted to the extremely cold climate of the Arctic Tundra. Other regions listed do not support these specific species.

The natives of the North-American tundra are known as The Eskimos.

The northern part of the continents within the polar region is known as the Tundra region. Tundra regions are found in the northern and southern hemispheres between the ice-covered poles and the coniferous forests. In the north, this biome stretches across northern Canada and Alaska, Siberia and northern Scandinavia, on or close to the Arctic Circle. There are also areas of tundra in coastal Antarctica.

Due to the cold, the upper soil surface of the tundra region is frozen into a rock-like state all through the year. This is called permafrost. It comprises 24% of land in Northern Hemisphere. A massive amount of carbon is found in permafrost. Structurally, permafrost is important. Erosion, disappearance of lakes, landslides, and ground subsidence is caused by the melting of permafrost. It also causes changes in composition of plant species at high altitudes.

Tundra has cold and dry Climate. It is covered with snow and is very cold throughout the year. There is no sunshine in the winter season of the year, both days and nights are dark. In the month of February-March, the sun begins to shine. Sun shines for the whole day and night. This tundra region is also known as the land of the midnight sun. There are nearly six months' day and six months' night in the tundra region.
