Answer:
Climatic conditions in the polar region are always on the extreme side. There is extreme cold and most of the areas are covered with snow. The sunrise and sunset persist for 6 months. The winters are so cold that the temperature falls to -37 0c.
Adaptions of Penguins
Its white colour helps it blend in with the white background
Thick skin and a lot of fat protect it from cold
They huddle together in groups to keep themselves warm
They have webbed feet and they streamline their body while swimming which makes them good swimmers.
Adaptations of Polar Bear
Their white fur gets camouflaged against the white background of snow protecting it from predators and also helps them catch their prey.
Two thick layers of fur act as an insulator protecting them from the surrounding harsh climate.
The polar bear carries out physical activities like swimming in order to keep warm
In order to avoid getting overheated they move slowly and rest often.
A strong sense of smell helps them in catching a prey

Explanation :
The other animals living in polar regions include a variety of fishes, reindeers, seals, whales, foxes and birds. While fish are able to remain underwater for long periods of time and survive the cold weather, the birds cannot do that. They migrate to warmer regions till the winter gets over. India is amongst the favourite destination amongst these birds. An example of this is the Siberian crane that migrates to the regions of Bharatpur in Rajasthan as well as Sultanpur in Haryana. The wetlands of North East and some other parts of India also serve as their destination to escape from the extreme climates.
