Subtropical tidal reefs and rocky reefs. Occurrences. Zavora. Geographic distribution. Indo-west Pacific. Japan (Gosliner et al . 2008), Papua New Guinea , Philippines ( Pola et al. 2008 ), South Africa ( Gosliner 1987 ) and Mozambique . Remarks. Often found feeding on the ascidian Eudistoma caeruleum (Sluiter, 1909) , this species is very similar to the description of N. yonowae , although it was only based on external morphology and no type material exists ( Goethel & Debelius 1992 ). Since species of the genus Nembrotha can be highly variable in colour, it is difficult to confirm this identification. Moreover, Pola et al . (2008) note that, so far, there are no clear differences between N. nigerrima , N. cristata and N. yonowae . Therefore additional studies are needed to clarify this potential complex.
