Explanation

To determine which of the following organisms eats its prey: leech, sepia, or starfish, we can analyze each option step by step.

### Step-by-Step Solution:

1. **Analyze the Leech**:
- Leeches are known to be parasitic organisms. They attach themselves to a host and feed by sucking blood or bodily fluids.
- **Conclusion**: Leeches do not eat their prey; they survive on their host.

2. **Analyze the Sepia**:
- Sepia, commonly known as cuttlefish, are carnivorous marine animals. They actively hunt and consume their prey, which typically includes small fish and crustaceans.
- **Conclusion**: Sepia does eat its prey.

3. **Analyze the Starfish**:
- Starfish are also carnivorous. They feed on mollusks, such as clams and oysters, by prying open their shells and everting their stomachs to digest the prey externally.
- **Conclusion**: Starfish do eat their prey.

4. **Final Conclusion**:
- Since leeches do not eat their prey, but both sepia and starfish do, the correct answer to the question is that sepia and starfish eat their prey.

### Answer:
The organisms that eat their prey are **sepia and starfish**.
