Step-by-step explanation:
The animals best suited to life at the North Pole are Arctic mammals like polar bears and seals.
These animals have specific adaptations that enable them to survive in the extreme cold conditions of the North Pole. For example, polar bears have thick fur and a dense layer of fat under their skin, which helps them to maintain their body temperature and reduce heat loss.
Seals, on the other hand, are adapted to living in icy waters and have streamlined bodies and flippers for efficient movement in the water, as well as a thick layer of blubber for insulation.
