Spicules are found in

Options

A. Herdmania
B. Sycon
C. Salpa
D. Both (1) & (2)

Answer

To answer the question "Spicules are found in," we need to analyze the options provided and understand where spicules are typically found in the animal kingdom.

### Step-by-Step Solution:

1. **Understanding Spicules**:
- Spicules are small, needle-like structures that provide support and protection to certain animals. They are commonly found in the exoskeletons of some organisms.

2. **Analyzing the Options**:
- **Option 1: Herdmania**:
- Herdmania is a genus of urochordates (tunicates). These organisms do have spicules, specifically calcareous spicules made of calcium carbonate, which contribute to their structure.

- **Option 2: Cyclone**:
- Cyclone is a member of the phylum Porifera (sponges). Sponges are known for their spicules, which can be made of silica or calcium carbonate. Therefore, spicules are present in this organism as well.

- **Option 3: Salpa**:
- Salpa is another type of urochordate. However, unlike Herdmania, Salpa does not have spicules; they lack these structures.

- **Option 4: Both 1 and 2**:
- Since both Herdmania (urochordate) and Cyclone (porifera) have spicules, this option is correct.

3. **Conclusion**:
- Based on the analysis, spicules are found in both Herdmania and Cyclone. Therefore, the correct answer is **Option 4: Both 1 and 2**.

### Final Answer:
Spicules are found in both Herdmania and Cyclone.
