2. They operate as a good insulator and prevent heat loss from the body.
3. Cold-blooded animals and cold-water fish have a thicker layer of subcutaneous fat to keep heat in their bodies and maintain body temperature.
4. The less heat is lost from the body, the thicker the layer of subcutaneous fat is.
