Crocodile swins in water by means of

Options

A. Laterally compressed tail
B. Webbed hind limbs
C. Wedded fore limbs
D. Both A and B

Answer

To determine how a crocodile swims in water, we need to analyze its anatomy and swimming techniques. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding Crocodile Anatomy**:
- Crocodiles have a unique body structure that aids in swimming. They possess a long, laterally compressed tail that is crucial for propulsion in water.

2. **Role of the Tail**:
- The crocodile uses its tail to create a wave-like motion. This lateral movement of the tail helps the crocodile push against the water, propelling itself forward.

3. **Leg Positioning**:
- While swimming, crocodiles tuck their legs against their bodies. This positioning minimizes drag and allows for more streamlined movement through the water.

4. **Webbed Limbs**:
- Crocodiles have webbed hind limbs. Although these limbs are not primarily used for propulsion, they assist in maneuvering, making quick turns, and stabilizing the crocodile while swimming.

5. **Evaluating the Options**:
- The options provided are:
- A) Laterally compressed tail
- B) Webbed hind limbs
- C) Webbed forelimbs
- D) Both option A and option B
- Based on our analysis, both the laterally compressed tail and webbed hind limbs contribute to the crocodile's swimming ability.

6. **Conclusion**:
- Therefore, the correct answer is option D, which states that the crocodile swims in water by means of both the laterally compressed tail and webbed hind limbs.

### Final Answer:
- The crocodile swims in water by means of both the laterally compressed tail and webbed hind limbs (Option D).
