There is a variety of animals that you could find in the Tundra such as Polar bears and a Red Fox

 

There are 8 main types of animals that live in the Tundra. 

 There is Red Foxes that you could find in every continent except for Antarctica. They are completely red except for the tip of its tail is white. They  are more active at night.

The second type of Animal is a Wolverine. This Wolverine is one of the most dangerous animals.  It looks like a grizzly bear. 

The third type of animal is a Canada lynx .They have long legs and broad paws which has been proven to help them walk through the snow easier. 

 Another species found in the tundra is the Beluga whale. They live in a range from the Alaska, Canada, Greenland, and Russia. They have been now classified as endangered animals.

. The fifht species in the Tundra is a Atlantic Puffin. They are found in part of Maine, Europe, and the Arctic Circle. They are carnivores .  
  

Arctic Hares are found in Alaska, Canada, and Greenland. These animals are interesting because they change their coat to white in the winter to be able to blend in with the snow. They are mammals and are Omnivores.

The Polar Bear. They have been classified as dangerous. They usually feed on seals. They are mammals and carnivores. 

They have also been known to be great swimmers.

Narwhals are sea animals that live in cold climates. They have a interesting nickname that is unicorn of the sea because of their long tusk. They can been found in Greenland and Canada. 

The Caribou its like a reindeer. Caribou can be found in northern and southern Alaska, Canada, Russia, and Greenland. They are mammals and herbivores. They are endangered. 

There are also biomes similar to those of tundra due to the effect of height (moorland), as in Tibet and at various levels of mountains around the world, as occurs in tropical areas of Peru and Bolivia.

VEGETATION
Plant life is exposed to low temperatures which makes it difficult for it to survive due to the difficulty in obtaining water, which is frozen for most of the year. Furthermore, the

mineralized organic material is very poor due to the low decomposition rate of the organic material. In tundras where temperatures are below 10 ° C in the coldest month and annual periods without ice for less than 3 months, tree growth is impossible, so common plants are mosses and lichens, which do not exceed 10 cm. high, thanks to strong winds that make them stay close to the ground.

Typical Arctic vegetation is made up of deciduous grasses and dwarf shrubs from the ericaceae family, along with moss and lichen associations. These plant communities are adapted to strong winds and ice disturbances in the soils. They can all photosynthesize at low temperatures and with low light intensity during long periods of daylight in the tundra.

Mountain plant communities are made up of tangled plants that do not occur in the Arctic. These plants adapt to gusty winds, heavy snowfall and large thermal fluctuations. They photosynthesize under very intense light during short periods of sunlight.

FAUNA
The fauna, in the tundras, has the need to protect themselves from the cold, for this the different organisms have different ways to protect themselves from the cold depending on their temperature regulation. Thus, some animals develop a dense coat and accumulate a large amount of subcutaneous fat, their surface volume ratio is as small as possible in order to isolate themselves from the cold. Among the animals we can find herbivores, such as caribou, reindeer, musk ox, arctic hare, snow goat and lemming, and carnivores, such as the white bear (in the extreme north) wolf, gyrfalcon, kodiak bear and the snowy owl; salmon are, to a large extent, the base of the food web for the fauna of this biome. Animal life is particularly sensitive to the destruction of its environment, being directly affected by excessive hunting, which can lead to the extinction of any animal or plant species in this fragile and interdependent biological community.

CLIMATE
The tundra's climate is characterized by its harsh winters, low temperatures, little rain or snowfall and short summers. For example, the monthly average of Baffin's Earth temperatures ranges from 7 ° C to -31 ° C and the annual average is -12 ° C. In the interior of the continents the temperatures tend to be extreme, so there is no variation in the annual averages.
The combination of frozen soil and flat surfaces of the tundra prevents the drainage of water, which stagnates on the surface or saturates the upper layer of the terrain. Lagoons and swamps are formed that provide moisture to the plants, which compensates for the low rainfall.

Periodic freezing and thawing of the soil in the best-drained places produces regular cracks in the soil that form polygons. Where drainage is worse, rough, irregular shapes appear, with mounds, frozen nodules and earth cords. In summer, the melting of the slopes can cause the soils to slide and produce terraces caused by solifluction or landslides.

All these models described for the arctic tundra appear on a smaller scale in the alpine tundra. The landscape of bare rock covered with lichens is also common, which is called the paramo. These landforms promote a series of small habitats that give variety to the landscape of the tundra.

A large amount of large-sized herbivores live in the savannah: zebras, antelopes, giraffes, rhinoceroses, elephants.
The carnivores of the savannah are:
 lions, hyena-dogs, hyenas and jackals. They hunt in groups according to specific strategies. 

The savannah is also inhabited by large birds: the Ratitae (ostrich, rhea), great bustard, guinea-fowl and marabou. Also, in the savannah, we can find many insects like: ants, termites and grasshoppers. These animals feed on local vegetation.
