One 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.

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 starfish ectotherms or endotherms?
A starfish is a ectotherm. (ectotherm means cold blooded)
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 are ectotherms?
Ectotherms (from Latin for outside heat) are animals whose body temperature is controlled by their behavior or by their external environment. The term is generally applied to "poikilotherms" whose temperature fluctuates directly with the ambient temperature of their surroundings.Formerly referred to as "cold blooded", ectotherms include reptiles, fish, and amphibians. "Warm-blooded" animals are also called "homeotherms" (Latin same temperature) and use their metabolism to heat and cool themselves.
Are puffins endotherms or ectotherms?
They are endotherms
Are grizzly bears endotherms or ectotherms?
The black bear is endothermic
Are toy poodles endotherms or ectotherms?
All mammals are endothermic (warm blooded). Ectotherms are cold blooded animals like snakes and lizards.
What is another name for coldblood?
Cold-blooded animals are poikilotherms (or ectotherms), while warmblooded animals are homeotherms (or endotherms).
Are doves endotherms or ectotherms?
endothermic
Are mice ectotherms or endotherms?
Endotherm.
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 sea turtles endotherms or ectotherms?
Ectotherms their body temperature changes with the environment
Are amphibians endotherns or ectotherns?
Endotherms are warmblooded, ectotherms are coldblooded, so amphibians are ectotherms.
Are Salamanders ectotherms?
Salamanders are endotherms.
Are dolphins ectotherms?
No, a dolphin is a mammal and all mammals are endotherms.
How do metabolic rates of ectotherms and endotherms compare?
Ectotherms have lower metabolic rates than endotherms because they rely on external sources of heat for regulating their body temperature, while endotherms generate heat internally. Endotherms have higher metabolic rates to maintain their body temperature within a narrow range, compared to ectotherms whose metabolic rates can vary more with environmental temperature.
