Seal is a mammal. How can it survive in the cold polar seas when a human would die in a few minutes?

Seals have several adaptations that allow them to thrive in cold polar seas, including a thick layer of blubber that provides insulation and energy reserves. Their fur also helps to trap heat, while their ability to regulate blood flow keeps vital organs warm. Additionally, seals can slow their metabolism and have specialized circulatory systems that minimize heat loss, enabling them to withstand extreme cold for extended periods.
