Find out incorrect match between animals and their features .

Options

A. Pseudocoelomates : Ancylostoma and Ascaris
B. Radiata : Asterias and Ascidia
C. Metagenesis : Obelia and physalia
D. Bioluminescence : pleurobranchia and Ctenoplana

Answer

To solve the question of finding the incorrect match between animals and their features, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the First Option: Pseudosilomids - Chylostoma and Ascaris**
- Chylostoma (hookworm) and Ascaris (roundworm) both belong to the phylum Aschelminthes, which consists of pseudocoelomates.
- **Conclusion:** This match is correct.

2. **Identify the Second Option: Radiata - Asteriasis and Acidia**
- Asteriasis (starfish) belongs to the phylum Echinodermata, while Acidia (sea squirt) belongs to the phylum Urochordata (or Eurocordata).
- **Conclusion:** This match is incorrect as both belong to different phyla.

3. **Identify the Third Option: Metagenesis - Obelia and Pheizelia**
- Metagenesis refers to the alternation of generations, which is characteristic of the phylum Cnidaria. Obelia and Pheizelia (Portuguese man of war) are both members of this phylum.
- **Conclusion:** This match is correct.

4. **Identify the Fourth Option: Bioluminescence - Pleurobrachia and Tenoplana**
- Bioluminescence is a property of the phylum Ctenophora. Both Pleurobrachia and Tenoplana are examples of organisms that exhibit bioluminescence.
- **Conclusion:** This match is correct.

### Final Conclusion:
The incorrect match is found in the second option: Radiata - Asteriasis and Acidia. Therefore, the answer to the question is option number 2.
