Seals are fat primarily due to a thick layer of blubber, which serves several essential functions. This fat layer provides insulation against cold water temperatures, helps with buoyancy, and serves as an energy reserve during periods of food scarcity. Additionally, the blubber aids in protecting vital organs and contributes to their streamlined shape for efficient swimming. Overall, being fat is crucial for their survival in harsh marine environments.
