Poikilotherms are organisms that cannot regulate their body temperature internally and instead rely on external sources to maintain their body temperature. This means that their body temperature fluctuates with the temperature of their environment. Poikilotherms are also known as ectotherms.
Most reptiles, amphibians, fish, and invertebrates are poikilotherms. They are able to survive in a wide range of temperatures, but their activity levels and metabolism are influenced by the temperature of their surroundings. Poikilotherms often bask in the sun or seek shade to regulate their body temperature.
In contrast, homeotherms, or endotherms, are organisms that can regulate their body temperature internally and maintain a relatively constant temperature regardless of external conditions. Birds and mammals are examples of homeotherms.

Poikilotherms, also known as ectotherms or cold-blooded animals, are organisms that rely on external sources of heat to regulate their body temperature. They are unable to generate their own body heat and must rely on the environment to maintain a stable internal temperature.
Characteristics of Poikilotherms:
1. External Heat Regulation: Poikilotherms cannot internally regulate their body temperature and rely on external sources such as sunlight, warm air, or water to maintain their body temperature.
2. Cold-Blooded: Due to their dependence on external heat sources, poikilotherms are often referred to as cold-blooded animals, even though their body temperature may vary widely depending on the surrounding environment.
3. Environmental Dependence: Poikilotherms are highly influenced by their external environment. Their body temperature fluctuates with changes in ambient temperature, and they may become inactive or hibernate during cold periods.
4. Behavioral Adaptations: To maintain their body temperature, poikilotherms exhibit various behavioral adaptations, such as basking in the sun, seeking shelter in warm areas, or burrowing underground to escape cold temperatures.
5. Activity Patterns: The activity patterns of poikilotherms are often influenced by temperature. They may be more active during warmer periods when their body temperature is higher and less active during cooler periods when their body temperature drops.
Examples of Poikilotherms:
1. Reptiles (snakes, lizards, turtles): Reptiles are classic examples of poikilotherms, often basking in the sun to absorb heat and regulate their body temperature.
2. Amphibians (frogs, toads): Amphibians also rely on external heat sources to maintain their body temperature, often inhabiting warm and humid environments or seeking shelter in water bodies.
3. Fish: Most fish are poikilothermic, utilizing the temperature of the water they inhabit to regulate their body temperature.
4. Insects: Insects are small, poikilothermic animals that rely on external heat sources to maintain their body temperature. They often seek shelter in warm areas or bask in the sun to increase their body temperature.
5. Some Plants: Certain plants may also exhibit poikilothermic characteristics, responding to changes in ambient temperature by altering their growth, metabolism, or flowering patterns.
