Marine mammals have a multitude of adaptations that allow them to survive in colder waters. Blubber is one such adaptation, serving as a thermal insulator to maintain body heat. Additionally, many marine mammals have a fur coating that provides an extra layer of insulation, as well as thick layers of skin to protect against the harsh elements.
Marine mammals survive in colder waters through:
1. Insulating blubber to retain body heat.
2. Counter-current heat exchange to minimize heat loss.
3. Thick fur or hair that traps air for additional insulation.
4. Decreased peripheral blood flow to conserve heat.
5. Diving adaptations to access colder waters and conserve energy.
6. Migration and seasonal movements to follow food sources in colder regions.

Marine mammals have adapted a variety of strategies to survive in colder waters. They have thick layers of blubber to help keep them warm, and they use their flippers to help them swim faster and conserve energy. They also have a layer of fur that helps to keep them warm, and they can dive to depths where the water is warmer. In addition, some species migrate to warmer waters during the winter months to escape the cold.
