Which animals are live in a cold place?(two)and about them

北極熊，又稱白熊，是在北極圈裡土生土長的熊，牠是陸上最龐大的肉食動物。在牠生存的空間裡，牠是食物鏈最頂層。牠擁有極厚的鯨脂及毛髮來保暖，其白色的外表在雪白的雪地上是良好的保護色，而且牠可以在陸上及海上捕捉食物，因此牠能在北極這種極嚴酷的氣候裡生存。

The polar bear (Ursus maritimus) is a bear native to the Arctic. Polar bears and Kodiak bears are the world's largest land carnivores, with most adult males weighing 300-600 kg (660-1320 lb); adult females are about half the size of males. Its fur is hollow and translucent, but usually appears as white or cream colored, thus providing the animal with effective camouflage. Its skin is actually black in color. Its thick blubber and fur insulate it against the cold. The bear has a short tail and small ears that help reduce heat loss, as well as a relatively small head and long, tapered body to streamline it for swimming.

A semi-aquatic marine mammal, the polar bear has adapted for life on a combination of land, sea, and ice,[2] and is the apex predator within its range.[3] It feeds mainly on seals, young walruses, and whales, although it will eat anything it can kill.

The polar bear is a vulnerable species at high risk of extinction. Zoologists and climatologists believe that the projected decreases in the polar sea ice due to global warming will reduce their population by two thirds by mid-century.[4][1][5][6] Local long-term studies show that 7 out of 19 subpopulations are declining or already severely reduced.[7][8] In the USA, the Center for Biological Diversity petitioned to up-list the legal conservation status of polar bears to threatened species in 2005.[9] This petition is still under review.

Penguin

Adults average 1.2 meters (4 ft.) in length and weigh 30 kilograms (75 lb) or more. The largest known individual was about 46 kg. The head and wings are black, the abdomen white, back bluish grey, and the bill is purplish pink. On the sides of the neck, there are two golden circular stripes. Like the King Penguin counterpart, a male Emperor Penguin has an abdominal fold, the "brood pouch", between its legs and lower abdomen.

The Emperor penguin has a thick coat of feathers that insulate the entire body, excluding only the legs and the undersides of the wings. The feathers provide a waterproof layer around the penguin's body.


Emperor penguin chick
Emperor penguin chicks are covered with a thick layer of light gray down. This covering ensures that they retain as much heat as possible, vital at this early stage when they are not capable of maintaining their body temperature. In addition, the infant emperor penguin's orbital area is covered in white downy feathers, unlike the all-black feathered head of the adult.

A distinguishing characteristic between males and females is their call. Each call is distinct. They also are related to the King and the chinstrap penguin.

Penguins (order Sphenisciformes, family Spheniscidae) are a group of aquatic, flightless birds living almost exclusively in the Southern Hemisphere.

The largest living species is the Emperor Penguin (Aptenodytes forsteri): adults average about 1.1 m (3 ft 7 in) tall and weigh 35 kg (75 lb) or more. The smallest penguin species is the Little Blue Penguin (also known as the Fairy Penguin), which stands around 40 cm tall (16 in) and weighs 1 kg (2.2 lb). Among extant penguins larger penguins inhabit colder regions, while smaller penguins are generally found in temperate or even tropical climates (see also Bergmann's Rule).

Most penguins feed on krill, fish, squid, and other forms of sealife caught while swimming underwater. They spend half of their life on land and half in the oceans
