Question

A baby dolphin is born into the ocean, which is a fairly cold environment. water has a high heat conductivity, so the thermal regulation of a newborn dolphin is quite important. it has been known for a long time that baby dolphins' blubber is different in composition and quantity from the blubber of adults. does this make the babies better protected from the cold compared to adults?

Answer 1

Ans.

Blubber is a fat-storage organ in mainly water-living mammals. It stores a large amount of brown fat tissue (brown adipose tissue) in young animals as compare to the adults that provides extra thickness to it. The extra amount of brown adipose tissue provides heat that acts as an effecient thermal insulator and helps on thermal regulation.

Thus, the blubber in baby dolphin shows a different composition of fat storage tissues that helps to survive them in cold temperature of ocean in their early stages of development.
