How does a narwhal survive in the cold waters?

Narwhals survive in cold waters primarily due to their thick layer of blubber, which provides insulation and energy reserves. They have also adapted to their environment with a unique circulatory system that helps regulate body temperature. Additionally, narwhals rely on their echolocation abilities to navigate and find food in dark, icy waters, allowing them to thrive despite harsh conditions. Their specialized diet of fish and squid, along with their ability to dive deep, further aids their survival in frigid habitats.
