Which of the following is incorrect match between organism and its larval form?

Options

A. Antedon-Doliolaria
B. Holothuria-Doliolaria
C. Ophiura- Ophiopluteus
D. Echinus-Echinopluteus

Answer

To determine which of the following is an incorrect match between an organism and its larval form, we will analyze each option provided.

1. **Option 1: Antidome - Dolyloria**
- The organism is Antidome and its larval form is Dolyloria.
- This is a correct match as Dolyloria is indeed a free-swimming larva associated with Antidome.

2. **Option 2: Holotheria - Dolyloria**
- The organism is Holotheria and its larval form is Dolyloria.
- This is an incorrect match. The correct larval form for Holotheria is Auricularia, not Dolyloria.

3. **Option 3: Ophiuria - Occiputus**
- The organism is Ophiuria and its larval form is Occiputus.
- This is a correct match. Occiputus is indeed the larval form of Ophiuria, which is a type of brittle star.

4. **Option 4: Echinus - Echinoplutus**
- The organism is Echinus and its larval form is Echinoplutus.
- This is a correct match. Echinoplutus is the planktonic larval form of Echinus.

After analyzing all options, we conclude that the incorrect match is:

**Answer: Option 2 (Holotheria - Dolyloria)**
