What is the opposite of ectotherms?

The opposite of ectothermic is endothermic. Ectotherms maintain their body temperature by behavior rather than metabolism. Endotherms maintain a warm, consistent body temperature with the use of energy.


Are horses endotherms or ectotherms?

Endothermic.


Which is better adapted to cold water an endotherm or ectotherm?

Endotherms are significantly better adapted to cold water and cold environments in general than ectotherms. This is because endotherms can operate at a temperature that is maximally efficient for the function of their enzymes.


What do scientist call warm-blooded and cold -blooded animals?

Scientists classify warm-blooded animals as "endotherms," which can regulate their body temperature internally, maintaining a stable temperature regardless of external conditions. Cold-blooded animals are referred to as "ectotherms," meaning their body temperature is largely determined by the environment. Examples of endotherms include mammals and birds, while reptiles, amphibians, and most fish are considered ectotherms.


What animals are both endotherms and ectotherms?

ectotherms, endotherms, warm-blooded, artery, internal, cold-blooded, shivers, calories, maintain, riverbank, environment, contrast, such, control, beaver, shiveringOne trait that distinguishes the major groups of vertebrates from one another is the way in which they control their body temperature. Most fish, amphibians, and reptiles have body temperatures that are close to the temperature of their environment.2 Fish, amphibians, and reptiles are ectotherms. An ectotherm is an animal whose body does not produce much internal heat. Its body temperature changes depending on the temperature of the environment. For example, when a turtle is lying in the sun on a riverbank, it has a higher body temperature than when it is swimming in a cool river. Ectotherms are sometimes called "cold-blooded," but that is misleading. The blood of ectotherms is often quite warm.3 In contrast to the turtle, a beaver would have the same body temperature whether it was in cool water or on warm land. The beaver is an endotherm. An endotherm is an animal whose body controls and regulates its temperature by controlling the internal heat it produces. An endotherm's body temperature usually does not change much, even when the temperature of its environment changes. Mammals and birds are endotherms. They have a stable body temperature that is typically much warmer than their environment. Endotherms are often called "warm-blooded" animals.
