what is blubber
Blubber is more vascularizedârich in blood vessels âthan other adipose tissue. Blubber has advantages over fur (as in sea otters) in the respect that although fur can retain heat by holding pockets of air, the air pockets will be expelled under pressure (while diving).Blubber, however, does not compress under pressure.It is effective enough that some whales can dwell in temperatures as low as 40 Â°F (4 Â°C). While diving in cold water, blood vessels covering the blubber constrict and decrease blood flow, thus increasing blubber's efficiency as an insulator.lubber from whales and seals contains omega-3 fatty acids and vitamin D. Without the vitamin D, for example, the Inuit and other natives of the Arctic would likely suffer from rickets.
