Salpa and Doliolum belong to

Options

A. Cephalochordata
B. Hemichordata
C. Tunicata
D. Cyclostomata

Answer

**Step-by-Step Solution:**

1. **Identify the Organisms**: The question asks about Salpa and Doliolum. These are both marine organisms that belong to a specific classification within the animal kingdom.

2. **Understand the Classification**: To determine the correct classification, we need to look at the different groups within the phylum Chordata. The main groups include Cephalochordata, Hemichordata, and Tunicata.

3. **Examine Cephalochordata**: This group includes organisms like Amphioxus, which have a notochord that extends from head to tail. However, Salpa and Doliolum do not belong to this group.

4. **Examine Hemichordata**: This group includes organisms that exhibit both chordate and non-chordate characteristics, such as Balanoglossus. Salpa and Doliolum are not classified here either.

5. **Examine Tunicata**: This group, also known as Urochordata, includes organisms where the notochord is present only in the tail region during their larval stage. Salpa and Doliolum fall under this category.

6. **Conclusion**: Based on the classification, Salpa and Doliolum belong to the phylum Tunicata.

**Final Answer**: Salpa and Doliolum belong to the phylum Tunicata.
