Sea otters exhibit an extraordinarily meticulous skin care routine that is vital for their survival in frigid ocean waters. These marine mammals spend a significant portion of their day grooming their dense, water-repellent fur, which is essential for insulation against the cold. Using their nimble paws, sea otters carefully scrub and smooth their fur, ensuring every inch remains clean and well-oiled. This grooming not only maintains the fur’s waterproof properties but also helps to trap air close to their bodies, providing crucial thermal protection. Their dedication to this daily ritual highlights the importance of fur maintenance in their harsh, aquatic environment.
