Poikilotherms are organisms that cannot regulate their body temperature internally and rely on external sources of heat to maintain their body temperature. Their body temperature fluctuates with the temperature of their environment. Examples of poikilotherms include reptiles, amphibians, and most fish.
Homeothermic organisms, on the other hand, are able to regulate their body temperature internally and maintain a relatively constant body temperature regardless of the external temperature. This is achieved through physiological mechanisms such as shivering to generate heat or sweating to cool down. Mammals and birds are examples of homeothermic organisms.

Poikilotherms (or Ectotherms):
- Temperature regulation: Rely on external sources (e.g., sunlight, water) to regulate their body temperature.
- Body temperature: Varies with the environmental temperature.
- Examples: Reptiles, amphibians, fish, invertebrates.
- Advantages: Can adapt to changing temperatures, conserving energy in cold environments.
- Disadvantages: Limited activity in extreme hot or cold temperatures.
Homeotherms (or Endotherms):
- Temperature regulation: Maintain a constant body temperature internally, regardless of the external environment.
- Body temperature: Regulated through metabolic processes (e.g., shivering, sweating).
- Examples: Mammals, birds.
- Advantages: Can stay active regardless of environmental temperature, allowing for a wider range of habitats and activities.
- Disadvantages: Require significant energy expenditure to maintain body temperature.
Key Differences:
- Temperature control: Poikilotherms rely on external sources, while homeotherms regulate temperature internally.
- Body temperature: Poikilotherms have variable body temperatures, while homeotherms maintain a constant temperature.
- Energy expenditure: Poikilotherms generally expend less energy on temperature regulation, while homeotherms require more energy.
- Habitat range: Poikilotherms are typically found in environments with minimal temperature variation, while homeotherms can inhabit a wider range of habitats.
- Activity levels: Poikilotherms have limited activity levels in extreme temperatures, while homeotherms can maintain activity regardless of temperature.
