Type of body cavity (Coelom) in earthworm is:-

Options

A. Acoelomic
B. Schizocoel
C. Haemoicoelic
D. Enterocoelic

Answer

**Step-by-Step Solution:**

1. **Understanding Body Cavities**: Body cavities in animals can be classified into different types based on their formation and structure. The main types are acoelomate, pseudocoelomate, and coelomate.

2. **Identifying the Type in Earthworm**: Earthworms are classified as coelomates, meaning they possess a true body cavity. However, the specific type of coelom in earthworms is important to identify.

3. **Types of Coelom**: The types of coelom include:
- **Acoelomate**: No body cavity (e.g., flatworms).
- **Pseudocoelomate**: A body cavity that is not completely lined by mesoderm (e.g., roundworms).
- **Coelomate**: A body cavity that is completely lined by mesoderm.

4. **Schizocoelom**: In the case of earthworms, the body cavity is formed by the splitting of the embryonic mesoderm. This type of coelom is referred to as a **schizocoelom**.

5. **Conclusion**: Therefore, the type of body cavity (coelom) in earthworms is a **schizocoelom**.
