Differentiate between Homoeothermal and poikilothermal animals

Explanation

### Step-by-Step Solution

1. **Definition of Terms**:
- **Homeothermal Animals**: These are also known as warm-blooded or endothermic animals. They have the ability to maintain a stable internal body temperature regardless of external environmental conditions.
- **Poikilothermal Animals**: These are referred to as cold-blooded or ectothermic animals. Their internal body temperature varies with the external temperature.

2. **Thermoregulation**:
- **Homeothermal Animals**: They can regulate their body temperature through various physiological mechanisms. This allows them to keep their internal environment constant, which is crucial for optimal metabolic functioning.
