Diaphoresis, sweating
convection
No, fat associated with skin prevents heat loss. Keratin and sebum associated with skin prevent water loss.
They dilate at the surface of the skin to release heat into the atmosphere, and they can also constrict to reduce heat loss through the skin.

For what?It requires a heat gain for the water,but a heat loss for whatever the water is in contact with.
The primary site of heat loss from the body is the skin. Its not necessarily the head or feet. It is just the skin. "The skin is the primary site of heat loss. the circulating blood brings heat to the skin's surface, where small connections between the arterioles and the venules lie directly below the skin surface. Other heat losses occur through evaporation of sweat, through warming and humidifying of inspired air and through the elimination of urine and feces."

Penguins have a counter current heat exchange mechanism. The warm blood entering their flippers flows past cold blood leaving. This warms the cold blood and cools the warm blood thus reducing heat loss from the flippers.

Heat is produced in several of the body's major organs, such as the Liver, Stomach and Heart. This heat is transferred throughout the body via the blood stream. Heat is lost via exhaling, and is commonly lost from our bodies through our skin, especially on hot days when the capillaries beneath the surface of our skin dilate to release more heat in order to cool down the body. We also lose heat when we sweat, via the same mechanism I just described with the capillaries, as well as when we urinate. I hope this has been helpful.
No, it drys out there skin and then they die from the heat and loss of moisture in there body.
The SUBCUTENOUS FAT LAYER which is made ou of fatty tissue that prevents the quick loss of heat and promote quick absorption of heat
