Mammals that live in the Arctic Ocean have a large amount of blubber, which is a fatty tissue just beneath the skin. Which statement best relates why these animals have so much blubber?

The correct answer should be something along the lines of keeping warmth in the cold environment or fats keep them warm or something like that. They have these lipids that insulate them from the heat and it envelops and protects their vital organs and this way they can survive the immense cold and the freezing water.
