Earthworms can feel the vibrations of the gound by presence of

Options

A. Buccal receptors
B. Photoreceptors
C. Epidermal receptors
D. Chemoreceptors

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks how earthworms can feel vibrations in the ground. This requires knowledge of the sensory structures present in earthworms.

2. **Analyzing the Options**:
- **Buccal Receptors**: These are located in the buccal chamber and are involved in taste and smell (gustatory and olfactory functions). They do not play a role in sensing ground vibrations.
- **Photoreceptors**: These receptors are sensitive to light and are located on the dorsal surface of the earthworm. They help in detecting light intensity and duration but are not involved in sensing vibrations.
- **Epidermal Receptors**: These receptors are distributed throughout the epidermis of the earthworm and are involved in tactile sensations. They are more abundant on the lateral sides and ventral surface, allowing the earthworm to detect vibrations from the ground.
- **Chemoreceptors**: These receptors detect chemical stimuli in the environment, allowing the earthworm to taste substances in the soil. They do not specifically respond to vibrations.

3. **Identifying the Correct Answer**: Since the question specifically asks about the ability to feel vibrations, the epidermal receptors are the most relevant option, as they are responsible for tactile sensations and can detect vibrations from the ground.

4. **Conclusion**: Therefore, the correct answer is **epidermal receptors**.
