- The phylum Arthropoda is characterized by:
- **Segmented Body**: The body is divided into segments, typically including a head, thorax, and abdomen.
- **Exoskeleton**: They possess an exoskeleton made of **chitin**, which provides structural support and protection.
- **Jointed Appendages**: Arthropods have jointed appendages that are adapted for various functions such as locomotion, feeding, and reproduction.

4. **Identify the Common Feature**:
- From the characteristics of Arthropoda, we can conclude that the common feature among silverfish, scorpion, dragonfly, and prawn is the presence of a **chitinous exoskeleton** and **jointed appendages**.

5. **Final Answer**:
- The common feature in silverfish, scorpion, dragonfly, and prawn is that they all have a **chitinous exoskeleton** and **jointed appendages**, which are characteristic of the phylum Arthropoda.
