Peripatus is a connecting link between

Options

A. Ctenophora and Platyhelminthes
B. Mollusca and Echinodermata
C. Annelida and Arthropoda
D. Coelenterata and Porifera

Explanation

**Step-by-Step Solution:**

1. **Understanding the Concept of Connecting Links:**
- A connecting link in biology refers to an organism that exhibits characteristics of two different groups or phyla, indicating a common evolutionary ancestor.

2. **Identifying Peripatus:**
- Peripatus, commonly known as the velvet worm, is an organism that does not fit neatly into one specific phylum due to its unique characteristics.

3. **Analyzing Characteristics of Peripatus:**
- Peripatus displays features of both annelids (segmented worms) and arthropods (insects, arachnids, etc.).
- It shows segmentation similar to annelids, which includes a body structure divided into segments.
- However, it also possesses certain arthropod-like features, such as a cuticle covering its body.

4. **Determining the Phyla:**
- Based on the characteristics observed, Peripatus serves as a connecting link between:
- **Phylum Annelida** (which includes segmented worms like earthworms and leeches)
- **Phylum Arthropoda** (which includes jointed-legged animals like insects and crustaceans)

5. **Conclusion:**
- Therefore, Peripatus is recognized as a connecting link between the phyla Annelida and Arthropoda, illustrating the evolutionary relationship and common ancestry between these two groups.
