? Cold-blooded animals refer to animals whose body temperature is not constant. The body temperature of these animals will change with the temperature of the external environment. The opposite is the homeotherm, refers to the body temperature has been kept stable animals, higher animals are generally homeotherm, such as man is a very typical homeotherm. Dolphin is also a kind of higher animal. Like human, it is a mammal. Its body temperature is constant. It is a warm-blooded animal, not a cold-blooded animal. The body temperature of
dolphins does not change with the temperature of the outside sea water. Some people think that they are cold-blooded animals because their body surface feels cool, which is actually a misunderstanding. The body surface of dolphins is relatively cool, because of long-term exposure to sea water, in fact, their internal important organs, such as the brain, heart and other important internal organs are thermostatic, belonging to a more typical warm-blooded animals, not cold-blooded animals.
above, dolphins are warm-blooded animals, not cold-blooded animals. For cold-blooded animals, because their body temperature is not constant, it will change according to the surrounding environment, and when winter comes, their activity will become very low, so that they enter a state of hibernation. Hibernation is a characteristic of many cold-blooded animals. Because dolphins are not cold-blooded animals, they do not have the habit of hibernation. When winter comes, the dolphin's body temperature is still constant and does not have much effect on their activity.
