Semicircular canal in the internal ear is the feature of
(a) Herdmania
(b) Lancelet
(c) Myxine
(d) Sea squirt

Options

A. Herdmania
B. Lancelet
C. Myxine
D. Sea squirt

Answer

To solve the question regarding which organism has semicircular canals in the internal ear, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks which of the given organisms has semicircular canals in their internal ear. The options provided are Herdmania, Lancelet, Myxine, and Sea Squirt.

2. **Define Semicircular Canals**: Semicircular canals are fluid-filled structures in the inner ear that help maintain balance and spatial orientation. They are primarily found in vertebrates.

3. **Analyze Each Option**:
- **Herdmania**: This is a type of tunicate (sea squirt) and does not possess semicircular canals.
- **Lancelet**: Lancelets are primitive chordates and do not have a developed internal ear structure, including semicircular canals.
- **Myxine**: Myxine, also known as hagfish, is a jawless fish that possesses semicircular canals, which are crucial for balance.
- **Sea Squirt**: Similar to Herdmania, sea squirts are tunicates and do not have semicircular canals.

4. **Identify the Correct Answer**: Based on the analysis, the only organism among the options that has semicircular canals is Myxine.

5. **Conclusion**: Therefore, the correct answer is (c) Myxine.

### Final Answer:
(c) Myxine
