Self - Protection Of Whales
A whale is a kind of warm - blooded animal, body temperature is always maintained at 37.d egree. C., and a human body temperature but almost , seawater is cool, especially in the Arctic, the water temperature is subzero Chang , seawater is cool, especially in the Arctic, the water temperature is subzero Chang .
Also, water absorbs heat much faster than the speed of the air, so whales have thick spongy layer of the skin layer and the insulating layer as a thick layer of fat below, in order to ensure the body heat is dissipated with minimum Also, water absorbs heat much faster than the speed of the air, so whales have thick spongy layer of the skin layer and the insulating layer as a thick layer of fat below, in order to ensure the body heat is dissipated with minimum . In addition, since the resistance of the water is much greater than that of air, so whales being set in motion that requires much more energy and stamina In addition, since the resistance of the water is much greater than that of air, so whales being set in motion that requires much more energy and stamina .

And, perhaps more importantly, although water resistance is great, but too large buoyancy, a whale of such behemoths, up to tens of meters, and weighing up to 100 tons, on land, would die without that, it is needless to say that the foraging, is also extremely difficult to come to life, so it's difficult to move And, perhaps more importantly, although water resistance is great, but too large buoyancy, a whale of such behemoths, up to tens of meters, and weighing up to 100 tons, on land, would die without that, it is needless to say that the foraging, is also extremely difficult to come to life, so it's difficult to move .
