How Do Whales Stay Warm?
Whales are warm-blooded mammals that can survive in water temperatures as frigid as the low 40s F. How do they manage to stay warm, even in the ice-cold waters of the Atlantic?
By wearing a thick layer of fat, called blubber, just beneath the skin. How does the whale acquire this fat layer? Food! An adult right whale, for example, may eat 2,000 lbs of food each day. In this experiment, you will find out how a whale’s blubber keeps them warm.
