The Hooded Seal is a marine mammal found primarily in the North Atlantic Ocean and Arctic regions. Known for its distinctive large, inflatable nasal cavity, males develop a colorful hood during mating season, which they use to attract females. These seals can grow up to 2.5 meters long and weigh around 300 kilograms. Hooded seals primarily feed on fish and squid, diving to depths of over 200 meters to hunt. They are known for their strong swimming abilities and can hold their breath for up to 30 minutes. Their population is monitored by organizations like the International Union for Conservation of Nature to ensure their conservation.
