Quizplus · Accepted Answer

Poikilothermic organisms, also known as cold-blooded organisms, are animals whose internal temperature varies with the temperature of their environment. Fish are an example of poikilothermic organisms as they typically have the same temperature as the water they live in. Homeothermic organisms (choice A) have a relatively constant internal body temperature regardless of the external environment, also known as warm-blooded animals. Endothermic (choice D) means the organism generates heat internally. So, none of these options fit for fish. Therefore, the correct answer is C.
