Species Account:

        Aeolidiella indica is considered to be very rare on Okinawa as I have collected only five individuals; the five specimens were collected simultaneous from the intertidal zone at the perimeter of a small commercial boat basin. The area was composed of strewn rock rubble amid silty sand. The specimens were found beneath two separate rocks as they were being overturned; the rocks were covered with a dense growth of a leafy green alga (Ulva sp.). One of the rocks supported two individuals while the other had three. Ova were seen in close proximity to both animal groups.

        One of the synonyms of Aeolidiella indica is Aeolidiella takanosimensis, which was described by Baba (1930).
