1. Blubber in marine mammals contains blood vessels and is adapted to serve as an adjustable warming and cooling mechanism.

2. The distribution of blubber in certain areas provides some marine mammals a more streamlined and hydrodynamic body shape.

3. Blubber serves as a source of water for marine mammals, which is crucial during fasting periods!

4. For keeping warm in cold water, blubber is much more effective than fur. Fur relies on trapping pockets of air among hairs to create a layer of insulation, but this air is lost during deep dives. In the ocean, blubber is the way to go.

      Hi Tiffany, I double checked the Encyclopedia of Marine Mammals and there is no mention of how much blubber on marine mammals weighs. Sorry I wasn’t able to help more.
