What is the difference between a Poikilotherm and an Ectotherm?
ectotherm: An animal that relies on external environment to regulate its internal body temperature. poikilotherm: An animal that varies its internal body temperature within a wide range of temperatures, usually as a result of variation in the environmental temperature.
What does the word Poikilotherm mean?
: an organism (such as a frog) with a variable body temperature that tends to fluctuate with and is similar to or slightly higher than the temperature of its environment : a cold-blooded organism.
What are Poikilotherms give one example?
An animal whose body temperature varies with the temperature of its surroundings; any animal except birds and mammals.
Are humans Poikilotherm?
Humans for example are in a critical condition if the temperature of their blood falls below 27 degrees Celsius. Fish, amphibians or reptiles are not greatly impacted by a slight drop in body temperature. They are among the poikilothermic organisms or ectotherms.
What does the term Endotherm mean?
Endotherm, so-called warm-blooded animals; that is, those that maintain a constant body temperature independent of the environment. The endotherms primarily include the birds and mammals; however, some fish are also endothermic.
Which classes are poikilothermic?
> Some examples of poikilotherms are fish, reptiles and amphibians and sloth. > Poikilotherms get heat from the environment and are called ectothermic animals.
Why are fish poikilotherms?
Fish, amphibians and reptiles belong to a group called ectotherms meaning that these animals do not produce heat to maintaining a constant and normally high body temperature (as is the case for birds and mammals). Instead they rely on the environment and their own behaviour to control their temperature.
Is a horse a Poikilotherm?
Cold-blooded animals are those animals that are not able to regulate their temperature of the body based on the surrounding temperature. Therefore, these animals are not able to survive at extreme temperatures. They are called the poikilothermic organism that includes Sea horses, Flying fish, and some reptiles.
