How do the sea lions adapt to the polar regions?

Sea lions, particularly the Arctic species like the Steller sea lion, adapt to polar regions through several physiological and behavioral traits. They have a thick layer of blubber that provides insulation against the cold temperatures, while their fur helps to keep them warm and dry. Additionally, sea lions are social animals, often found in large groups that can help conserve heat. Their diet is also adapted to local conditions, as they hunt for fish and other marine life available in polar waters.
