mouth of dugesia is

Options

A. Anterior
B. Antero - dorsal
C. Mid- ventral
D. Antero -ventral

Answer

To answer the question about the location of the mouth of Dugesia, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Dugesia**: Recognize that Dugesia is a type of flatworm, commonly referred to as Planaria. Understanding its classification helps in visualizing its anatomy.

2. **Understand Flatworm Anatomy**: Flatworms, including Dugesia, have a body that is dorsally (top side) and ventrally (bottom side) flattened. This unique shape is a key characteristic of flatworms.

3. **Locate the Mouth**: In Dugesia, the mouth is not located at the anterior (front) end of the body. Instead, it is situated in a specific position on the ventral side.

4. **Pharynx Structure**: The mouth of Dugesia is formed by an averted pharynx, which means that the pharynx can be extended outward. This structure is crucial for feeding.

5. **Determine the Position**: The averted pharynx, which acts as the mouth, is located in the middle of the ventral side of the body. Therefore, it is not at the anterior end but rather in the mid-ventral position.

6. **Select the Correct Answer**: Based on the anatomical position of the mouth, the correct answer to the question is "midventral."

### Final Answer:
The mouth of Dugesia is located in the **midventral** position.
