In earthworms, sperms are received during copulation inside special apertures known as

Options

A. Female genital pore
B. Clitellum
C. Spermathecal apertures
D. Coelomic epithelium

Explanation

To answer the question regarding the special apertures in earthworms where sperms are received during copulation, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Earthworm Reproduction**:
- Earthworms are hermaphroditic, meaning they possess both male and female reproductive organs. This allows them to engage in copulation with other earthworms.

2. **Identifying the Relevant Structures**:
- During copulation, earthworms exchange sperm. The structures involved in this process are critical to understanding where the sperm is received.

3. **Recognizing the Specific Aperture**:
- The sperm is received through a special aperture known as the **spermathecal aperture**. This aperture is located on the female side of the earthworm's body.

4. **Location of the Spermathecal Aperture**:
- The spermathecal apertures are found in the intersegmental septum between specific segments of the earthworm. For example, they can be located between the 5th and 6th segments, and similarly between other segments.

5. **Differentiating Between Other Structures**:
- It is important to distinguish the spermathecal aperture from other structures such as the female genital pore (which is involved in egg release), the clitellum (which forms the cocoon), and the coelomic epithelium (which does not play a role in sperm storage).

### Final Answer:
In earthworms, sperms are received during copulation inside special apertures known as **spermathecal apertures**.
