Answer

To determine which of the following matching pairs is wrong, we need to analyze each option carefully.

### Step-by-Step Solution:

1. **Identify the Options**:
We need to look at the pairs provided in the question. The question mentions "shellfish vs fishes" as the first option.

2. **Analyze the First Option**:
- **Shellfish**: This term refers to a variety of aquatic animals that have shells. Shellfish include organisms from the phylum Mollusca (like clams and oysters) and Echinodermata (like sea urchins).
- **Fishes**: These are typically defined as members of the class Actinopterygii or Chondrichthyes, which are true fish.
- **Conclusion**: Since shellfish are not true fish, this pair is a wrong match.

3. **Analyze Other Options**:
- **Silverfish**: This is an insect belonging to the class Insecta (Arthropoda). It is not a true fish. This pair is correct.
- **Cuttlefish**: This is a marine animal belonging to the class Cephalopoda (Mollusca). Despite its name, it is not a true fish. This pair is correct.
- **Starfish**: This is an echinoderm and not a true fish. This pair is also correct.

4. **Determine the Wrong Match**:
After analyzing all the options, the only incorrect matching pair is "shellfish vs fishes".

### Final Answer:
The wrong matching pair is **shellfish vs fishes**.
