How does blubber deal with water?

Blubber, a thick layer of fat found in marine mammals like seals and whales, helps to conserve body heat in cold water environments. It also plays a role in buoyancy and energy storage. Additionally, blubber aids in water regulation by minimizing water loss through the skin, which is crucial for maintaining hydration in a saline ocean environment. Overall, blubber is essential for thermoregulation and overall water balance in these animals.
