Polar Bear

  

Polar Bear (English: polar bear) or in its scientific name Ursus maritimus is a large mammal in the rules of the family of Ursidae biology.  He belongs to the circumpolar species found around the northernmost continent of the earth, the Arctic continent and is among the most carnivorous bears among other bear families.  Polar bears are sometimes also classified as marine mammals.

 Male polar bears weigh between 400-600 kilograms and can sometimes reach more than 800 kg with heights reaching more than 2.5 meters.  While female polar bears are only half the weight of male bears weighing between 200 - 300 kg and about 2 meters high.  Polar bears have a very sharp sense of smell.  they can smell whales or seals from 20 miles away.

 Polar bears are good swimmers because they can swim for 60 miles without stopping.  They use their front legs for swimming and their back legs as a steering wheel.  The oil glands on her skin can oil her fur well so that it is waterproof and keeps her body dry during swimming.

 In the summer in the Arctic, especially in May - June, thick bear feathers begin to fall to keep body temperature stable.

 Food

 The main food Polar bears are fish and seals.  They are animals who are patient when hunting, waiting for prey (seals) who are diving for hours until the target jumps to the mainland and then immediately pounced on a bear.  The paralyzing force of its prey is in the bear's sharp claws and the powerful punch from its front legs.

 An adult polar bear needs an assumption of 2kg of fat per day to survive in cold temperatures.  A seal weighing 55kg can meet food reserves for polar bears to survive for 8 days.

 Reproduction

 The mating season for polar bears occurs in the summer at the North Pole, which is between March - June.  Then babies polar bears will be born in December - January, usually they will give birth to 2-3 babies.

 

 During pregnancy, the mother bear will dig the nest in the snow and even sleep throughout the winter in the nest until the baby bears are born.  Even so, the mother bear does not feel dehydrated or lacking food to feed the baby bears that have been born.  The babies will live in the nest for approximately 28 months.  Newborn polar bears are only as big as rats. They do not have fur, are blind, and are weak at all. A female polar bear is proven to be the mother of the most devoted mammals in terms of looking after their children.

 Habitat of Life

 In general, polar bears live individually.  However, female polar bears will live in groups to protect one another when they are pregnant and when they are looking for food.

 Female bears will usually live along the Arctic coast, while male bears live on chunks of ice and float in the sea about 180 miles away from the coast.

 Polar bears are basically animals that are active and not at all afraid of human presence.
