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

cold -blooded animals are animals whose body temperatures are regulated by their environment and warm bleeds are animals whose body temperature is maintained by relatively constant internal mechanisms. Along with how their body temperatures differ, another main difference between these types of animals is that warm -blooded animals require more food. The terms "cold -blooded" and "thermally distorted" are misleading because the blood of animals of cold -blooded animals is not necessarily cold, it varies only depending on the environmental temperature. More accurate terms are "ectotermic" instead of "cold-blooded" and "endothermic" or "homeothermic" instead of "warm-red". Another term for ectotermic animals is "Poikiloterms", which means animals that have different body temperatures.

The vast majority of mammals and birds are warmly distorted, and almost all reptiles, fish, insects, amphibians and arachnids are cold -blooded. However, there are some exceptions and some animals that have the properties of both thoseMight. For example, bats and a mole rats are mammals, but their body temperatures may vary according to their environment, especially if they are not active. Certain insects, such as hawk moths and some bees, can increase body temperatures by beating their wings. Some fish have internal mechanisms that help prevent their brains and eyes from being too cold, which could disrupt their function.

food requirements

One of the significant differences between warm -blooded and cold -blooded animals is that warm -blooded animals usually need to survive three to 10 times as much food because they have to create their own body heat. In accordance with this, these endothermal animals must be well in obtaining food three times to 10 times, placed on another metabolic and evolutionary level. Ectotherms can rely on sunlight and other factors of the life of a heat rather than withI create it yourself, so their bodies need less food.

some advantages and disadvantages of each

There are several advantages that are endothermic - greater stamina, which has only one set of body enzymes that optimally operate at the set temperature and the ability to increase body temperature in freezing weather. Spider, who is caught in a blizzard, freezes firmly, but a human being has at least a chance of survival. Ectotermic animals must maintain several sets of enzymes for their biological processes because the enzymes are temperature sensitive, but endothermic animals can maintain one set.

The most useful advantage is endothermic is greater stamina. The endothermal creature can overtake a cold -blooded predator if it avoids the initial attack. Warm predators can overtake their ectotermic prey and endothermal animals can forage for a longer period of time. Some people could say that endothermal creatures are better because they tend to have more stamina butThey cannot move faster than cold -blooded animals for short explosions and starve more easier than ectotermal creatures.
