The polar bear is the largest terrestrial carnivore in the world, an animal of the bear genus Bears in the family Ursaceae, and an viviparous mammal, so it is not cold-blooded.
We go to the zoo to see many different areas of animals, including cute and dull polar bears, so it lives in such cold areas, is it a cold-blooded animal? Let me tell you next!
Details
01
Polar bears are also known as white bears. The skin is black, and the appearance is usually white due to the transparent hair, but also yellow and other colors. They are huge and ferocious. They are the largest terrestrial carnivores today. Adult polar bears stand upright up to 2.8 meters tall and have a shoulder height of 1.6 meters. Polar bears weigh 300 kilograms for males and 150 kilograms for females. They will accumulate a lot of fat before winter, and they can weigh more than 800 kilograms. Bear paws can reach 25cm wide, bear claws can exceed 10cm, polar bears can run at a speed of 40 kilometers per hour, and can swim 97 kilometers at a speed of 10 kilometers per hour in the sea.
02
Polar bears are so excellent swimmers that they were once considered marine animals. Polar bears spend most of their lives (about 66.6%) in a “static” state, such as sleeping, lying down, or waiting for prey. The remaining 29.1% of their time is spent walking or swimming on land or ice, 1.2% of their time is spent attacking prey, and the last remaining time is basically spent enjoying delicious food.
03
Polar bears have vision and hearing like humans, but they have a keen sense of smell, seven times as fast as dogs, and 60 km/h, 1.5 times faster than the world 100 m champion. Due to the rise of global temperature, the floating ice in the Arctic gradually begins to melt, the former home of polar bears has been damaged to some extent, and it is likely to become extinct in the near future, which needs human protection.
04
Although it is said that polar bears live in the cold Arctic, they are viviparous mammals. Generally speaking, mammals are warm-blooded animals, so polar bears cannot be cold-blooded animals.
