Latimeria swims by means of

Options

A. Flapping movement of its pectoral and pelvic fins
B. Rotational movement of its pectroal fins
C. Flapping movement of pectoral fins and rotational movement of pelvic fins
D. Rotational movement of tail fin

Answer

**Step-by-Step Solution:**

1. **Identify the Organism**: The question asks about Latimeria, which is a rare genus of fish known as coelacanths.

2. **Understand the Swimming Mechanism**: Latimeria is known for its unique swimming method. It was previously thought to be extinct until a specimen was found in 1938.

3. **Recognize the Types of Movement**: There are different types of fin movements in fish, including flapping and rotational movements.

4. **Determine the Correct Movement**: Latimeria swims primarily by using the rotational movement of its pectoral fins. This is a distinctive feature that sets it apart from many other fish that use flapping movements.

5. **Eliminate Incorrect Options**: The other options, such as flapping movements of the pectoral and pelvic fins, and rotational movement of the tail fin, do not accurately describe how Latimeria swims.

6. **Conclude the Answer**: Therefore, the correct answer to the question is that Latimeria swims by means of the rotational movement of its pectoral fins.

**Final Answer**: Latimeria swims by means of the rotational movement of its pectoral fins.
