Answer

To determine which of the given options has paddle-like limbs, we can analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Paddle-like Limbs**:
- Paddle-like limbs are adaptations that allow animals to swim efficiently. These limbs are typically flattened and modified into flippers.

2. **Analyzing the Options**:
- **Crocodile**:
- Crocodiles are reptiles that are semi-aquatic, meaning they can live both on land and in water. However, their limbs are not modified into paddles; they have more traditional limbs suited for walking and swimming but not specifically for paddling.
- **Conclusion**: Incorrect option.

- **Tortoise**:
- Tortoises are primarily terrestrial reptiles. They have limbs that are adapted for walking on land. While tortoises and turtles belong to the same order (Testudines), tortoises do not have adaptations for swimming.
- **Conclusion**: Incorrect option.

- **Turtle**:
- Turtles are primarily aquatic and have limbs that are modified into flippers, which are paddle-like. This adaptation allows them to swim efficiently in water.
- **Conclusion**: Correct option.

- **Sea Snake**:
- Sea snakes are limbless reptiles. They do not have any limbs at all, as they have adapted to a fully aquatic lifestyle without the need for limbs.
- **Conclusion**: Incorrect option.

3. **Final Answer**:
- The animal with paddle-like limbs is the **Turtle**.
