Options

A. Mollusca
B. Crustacea
C. Fishes
D. Insecta

Answer

**Step-by-Step Solution:**

1. **Understanding Shellfish**: Begin by recognizing what shellfish are. Shellfish are aquatic invertebrates, meaning they lack a backbone and are primarily found in water.

2. **Identifying the Taxonomic Groups**: Familiarize yourself with the taxonomic groups mentioned in the question:
- Mollusca
- Crustacea
- Fishes
- Insecta

3. **Analyzing Each Group**:
- **Mollusca**: This phylum includes animals such as snails, clams, and octopuses, which often have shells.
- **Crustacea**: This class includes crabs, lobsters, and shrimp, which are also considered shellfish but are not classified under the term "shellfish" in the broader sense.
- **Fishes**: These are vertebrates with gills and fins, which do not include shellfish.
- **Insecta**: This class includes insects, which are not aquatic and do not have shells like shellfish.

4. **Identifying the Correct Taxon**: Since shellfish are primarily associated with the phylum that includes animals with shells, the correct answer is **Mollusca**.

5. **Conclusion**: Therefore, shellfish are members of the taxon **Mollusca**.

**Final Answer**: Shellfish are members of the taxon **Mollusca**.
