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.

In order to avoid getting overheated they move slowly and rest often.
A strong sense of smell helps them in catching a prey.

Adaptations 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.
Other Animals Living in Polar Regions:-
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.
