Habitats. Subtropical tidal reefs, rocky reefs and tropical coral reefs.

Occurrences. Ponta do Ouro, Zavora, Nacala, Nuarro and Vamizi Island.

Geographic distribution. Indo-west, central Pacific. French Polynesia ( Pease 1871), Guam ( Carlson & Hoff 2003), Japan, Palau, Marshall Islands, New Zealand (Gosliner et al. 2008), Australia (Nimbs & Smith 2016), Philippines ( Debelius 1996), Thailand ( Mehrotra & Scott 2015), India ( Apte 2009; Bhave & Apte 2013), British Indian Ocean Territory ( Yonow et al. 2002), Red Sea, Tanzania, South Africa ( Debelius 1996), Mauritius (Gosliner et al. 2008) and Mozambique ( King & Fraser 2014).

Remarks. We found three-colour morphs in Mozambique. Morphotype 1 ( Fig. 10 F–G View FIGURE 10 ) had a distinctive purple-blue margin on the head and posterior end of the mantle with several white and dark bluish spots. The background colour varied from light-cream ( Fig. 10 F View FIGURE 10 ) to almost orange ( Fig. 10 G View FIGURE 10 ). Morphotype 2 ( Fig. 10 H View FIGURE 10 ) had an orange margin around the whole mantle edge, as well as white and purple spots. Morphotype 3 ( Fig. 10 I View FIGURE 10 ) lacked purple spots on the anterior mantle margin. The orange outer band is wider than morphotype 2. The evenly-spaced purple dots on the dorsum are larger than the other morphotypes. It is not clear if these morphotypes are mere colour variations or form part of a species complex. Gosliner et al. (2015) suggest that the morphotype 3 is a separate species.
