Detailed explanation-1: -Poikilotherms are cold blooded animals which cannot maintain constant body temperature and are hence affected by temperature changes in environment e.g., reptile, amphibians.
Detailed explanation-2: -Cold-blooded actually means the animal’s body temperature is basically the same as its surroundings. A fish swimming in 40° F water will have a body temperature very near 40° F. The same fish in 60° F water will have a body temperature near 60° F.
Detailed explanation-3: -Cold-blooded animals do not maintain a constant body temperature. They get their heat from the outside environment, so their body temperature fluctuates, based on external temperatures. If it is 50 °F outside, their body temperature will eventually drop to 50 °F, as well.
Detailed explanation-4: -Cold-blooded animals can be defined as animals that cannot regulate their internal body temperature with the change in the environment. They cannot survive in extreme temperature conditions.
Detailed explanation-5: -ectotherm, any so-called cold-blooded animal-that is, any animal whose regulation of body temperature depends on external sources, such as sunlight or a heated rock surface. The ectotherms include the fishes, amphibians, reptiles, and invertebrates.
