9 Polar Animals Story

A geographical pole means two points – the north pole and the south pole – on the surface of a planet or other rotating object. Which the spindle meets the surface of the object The north pole will be at an angle of 90 ° and above the equator. While the South Pole will be at an angle of 90 ° and below the equator. The pole may have a slight chance of moving slightly due to the rotation of the object itself. The true physical North and South Pole of the world may change its position within a few meters. The phenomenon is clear from the spin of the evolution of the world. Which degrees of the planet (Both the spindle and the surface are moving at the same time) may change position slowly over tens of thousands of years.

However, the scholars need to find polar coordinates that are accurate and do not change positions. Polar to map (cartographical poles or cartographic poles) are therefore fixed positions on Earth or other rotating objects at the approximate approximate position of the changing pole.

The weather

The North Pole and South Pole are extremely cold. Due to the orbit of the Earth around the sun Low concentration radiation The polar areas on both sides during the cold season are very cold. And the water freezes. And there is a strong wind that blows the snow down, known as Blizzards
plant. Because it is cold Therefore not many plants Some plants are highly durable. Sometimes it may sink under the snow. For years Before having the opportunity to grow again When summer arrives Durable grass and plants such as moss (Lossen) often have short shrubs.

Animal – animals in the Arctic
In the Arctic, a number of animals live throughout the year. But some are in warm season Most Arctic animals have thick fur for warmth, such as walruses, Musk oxen, polar bears and animals in the South Pole.

Oceans that surround the Antarctic Is the habitat of many animals But a few species that live in the Antarctic throughout the year, such as whales, seals, shrimp (Krill) bird. Penguins live only in the South Pole. Never appears in the North Pole. Most other birds live in the polar regions only during the summer, such as the white owl (Snowy owl).

There are mammals and empty animals. There are many types of eggs. Arctic is used to call the world’s northernmost oceans, including islands and surrounding coasts, all of which are geographically defined as the North Pole. Located at the point of Little Ursa (Ersar Minor) appeared in the sky With one star in this group called the North Star.

1. Walruses

Walrus “mammals Most of them live in the North Pole. And the Pacific Ocean There are many species together. Will be aggressive during the breeding season. Adult males may weigh up to 1,600 – 1,900 kilograms, or almost 2 tons, diving up to 90 meters deep, with their distinctive, long white tusks.

A musk cow is another herbivore that lives in this tundra. It weighs about four hundred kilograms, and the horns are long and formidable. The musk has two layers of wool, which will shed in the summer. The outer coat is a long, coarse hair, used for protection against cold weather. The inner coat is thick and short hair. Used for warming the body temperature They live in groups of tens of thousands and when being hunted by animals.

2. Reindeer

Reindeer have another name, Cariboo, which is a name people in Canada and the United States call. This type of deer has both male and female horns. They are avid travelers. Which will migrate for thousands of kilometers each year To find food and water sources.

3. seal

Name of large mammals in the Phocidae family. It has a mustache like a cat without ears, legs, like a pair of short front paws, a pair of backs along the trunk. Live along the coast Tricky food in warm or cold water.]
Sample: [The seals are snapping of everything thrown at it]

4. herbivore

Herbivore is smaller But there is an enormous amount of snow geese, which are both white and blue In the summer, millions of snow geese Will pair to build a nest and lay eggs in the tundra These geese have a few months to build a family and raise children. Before the cold season comes back Which at that time The young goose, large version, will fly back down to the warm south again.

5. Polar wolves

Polar wolves are the second predator in the ice land. Its main food is the tatami, the snow rabbit, the reindeer. But many times they attack musk cows, and weak and separated cows often become their food. Polar wolves live in pairs or in small groups that are most of the same blood. Male wolves are quite responsible for the family.

6. Beluga

Beluga looks like a big dolphin. Its skin is white. Therefore called white whales. They are four meters long. Like to live together as a family and be peaceful animals Like other types of whales in this land, such as arrowhead whales, right whales, gray whales and blue whales.

7. Gillemot birds

Gillemot birds along the coast cliff There are many kinds of seabirds nesting in the nest such as puffins that have strange beak. And the Gillermot bird that looks like a flying penguin The baby birds and the eggs become the food of the seagulls waiting for the opportunity to steal to eat. The eggs and some young birds that fell from the nest on the ridge. May become the food of the polar fox that eats below.

8. The whales

The whales in the cold waters are the blessed houses of the whales and beluga. Whales are whales and dolphins. The body is about three meters long. The male whale has a tooth on its upper limbs protruding outside its mouth. Looks like a unicorn twist. Make sometimes They are called The Unicorn of the Sea

9. Penguins

Classified in vertebrates, the poultry layer is inhabited in the South Pole Have flat wings for swimming paddles. Like to eat female fish, laying eggs for males to incubate Then the female will find food back The newborn penguin has a light gray fur, white face and a black head. Which the mother will recognize the child from the unique voice.
