- Peripatus has a worm-like body that is segmented, which is a defining feature of Annelida.
- It has a non-chitinous cuticle, which is also a characteristic of annelids.
- **From Arthropoda:**
- It possesses jointed legs, which are a primitive characteristic of arthropods.
- Peripatus has compound eyes, another trait associated with arthropods.
- It also has a tracheal system for respiration, which is typical in arthropods.

4. **Conclusion:**
- Given the combination of these characteristics, Peripatus is identified as a connecting link between Annelida and Arthropoda.

5. **Final Answer:**
- Therefore, the correct answer to the question is that Peripatus is a connecting link between Annelida and Arthropoda.
