The correct answer is b. thick layer of blubber.
Blubber is a fat layer made of adipose tissue. It is present beneath the skin covering entire body except in fins, flippers in all marine animals such as seals, whales and walruses. Blubber layer is thick that stores energy in the form of fats and proteins. It insulates heat it means fat layer keep marine animals warm in very cold water. Thus, blubber not help an animal to move through water.
Blubber refers to a thick sheet of fat which is also known as adipose tissue and is directly present under the skin of all the marine mammals.
Further Explanation:
The thick sheet of fat refers to blubber and is often observed in marine animals. This layer of fat mainly shields the whole body of animals like whales, seals, and walruses. It is a vital segment of the marine mammals anatomy. It is responsible for storing energy, elevates buoyancy, and also insulates the heat.
Energy is stored within the thick and oily sheet of fat and it involves both proteins as well as fats. The capability of this sheet to use these stored nutrients indicates that marine mammals are not enforced to look for source of food for a longer period of time. This sheet also insulates the animals and helps them to be warm in icy waters.
This insulation is essential for their survival. Mammals are known to be warm-blooded animals and their body temperature remains around the same irrespective of what the temperature is outside the body. Blubber aids in keeping the animals buoyant or float. It is usually less dense as compared to the ocean water around it and so the animals float naturally.
