What is the difference between warm-blooded and cold-blooded animals?

Cold blooded animals are animals whose body temperature is regulated by the surrounding environment, while warm blooded animals are animals whose body temperature is kept relatively constant by the internal mechanism In addition to differences in body temperature, another major difference between the two groups is that warm blooded animals need more food The words "cold blood" and "warm blood" are misleading, because cold-blooded animals are not necessarily cold, but change based on the temperature of the environment In fact, we should replace "cold blood" with "variable temperature", and replace "warm blood" with "endothermic" or "constant temperature" Another way to call a real cold-blooded animal is "variable temperature animal", which means that animals have different body temperatures Examples and exceptions most mammals and birds are warm blooded, and almost all reptiles, fish, insects, amphibians and arachnids are cold blooded But there are some exceptions, and some animals have two characteristics For example, bats and moles are mammals, but their body temperature can change according to the environment, especially when they are not active Some insects, including hawkmoths and some bees, can raise their body temperature by flapping their wings Some fish have internal mechanisms that prevent the brain and eyes from weakening as they get too cold One obvious difference between warm-blooded and cold-blooded animals is that warm blooded animals usually need 3-10 times as much food to survive because they have to produce their own body heat Based on this, these endothermic animals must get 3-10 times of food, so the level of metabolism and evolution is also very different Cold-blooded animals can rely on sunlight and other environmental factors to provide heat, and do not need to produce heat by themselves, so the body needs less food Advantages and disadvantages of each animal warm blooded animals have many advantages, such as stronger endurance, only a group of body enzymes to optimize the setting temperature, and the ability to increase body temperature in cold weather Spiders will freeze into solid when encountering heavy snow, but human beings have at least a chance to survive Cold blooded animals need to maintain multiple sets of enzymes for biological processes (because enzymes are sensitive to temperature), but warm blooded animals only need to maintain one set The biggest advantage of warm blooded animals is their endurance Compared with cold-blooded animals, warm-blooded animals can better avoid the initial attack Warm blooded predators can escape being prey to cold blooded animals, and they can look for food for a long time Some people might say that warm blooded animals are better because they have better endurance, but they don't erupt as fast in a short time as cold blooded animals, and they are more likely to starve than cold blooded animals.
