mode of feeding in tunicates is

Options

A. Mixotrophic
B. Parasitic
C. Macrophagous
D. Ciliary feeders

Answer

### Step-by-Step Solution:

1. **Understanding Tunicates**:
- Tunicates, also known as sea squirts, are marine animals that typically attach themselves to surfaces like rocks or the undersides of boats.

2. **Identifying Feeding Mechanism**:
- The mode of feeding in tunicates involves the use of a specialized structure known as the endostyle, which is located on their ventral surface.

3. **Role of the Endostyle**:
- The endostyle secretes a mucous net that captures food particles from the surrounding water.

4. **Ciliary Movement**:
- Tunicates utilize cilia (tiny hair-like structures) to create water currents that draw in seawater, allowing them to filter out planktonic particles for food.

5. **Classification of Feeding**:
- Due to their method of feeding, which relies on the movement of cilia and the capture of suspended particles, tunicates are classified as ciliary feeders.

6. **Conclusion**:
- Therefore, the mode of feeding in tunicates is best described as "ciliary feeders."
