* Insulation: Fur provides a layer of insulation, helping seals stay warm in cold waters. The thick blubber layer beneath their skin also contributes to this insulation.
* Camouflage: The color and texture of fur can help seals blend into their environment, making it easier to hunt prey and avoid predators.
* Protection: Fur can provide some protection from the elements, such as wind and rain. It can also help to prevent injuries from rocks and other sharp objects.
* Hydrodynamic efficiency: The smooth, streamlined fur of seals can help to reduce drag in the water, making it easier to swim.
Overall, fur is an important adaptation that helps seals survive in their aquatic environment.
