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

Occurrences. Zavora, Paindane, Nuarro and Vamizi Island.

Geographic distribution. Indo-west, central Pacific. Hawaii ( Kay & Young 1969), Guam ( Carlson & Hoff 2003), Japan ( Stimpson 1855), Australia ( O’Donoghue 1924; Burn 2006), Thailand ( Mehrotra & Scott 2015), India ( Apte 2009), Gulf of Oman ( Fatemi &Attaran-Fariman 2015), Red Sea ( Debelius 1996), South Africa ( Gosliner 1987) and Mozambique ( Macnae & Kalk 1958).

Remarks. Preliminary molecular analysis (Deneb Ortigosa, pers. communication) suggests that this taxon is a complex of species. Three colour-morphotypes were found: (1) a black dorsum with white spots and bluish foot edge ( Fig. 22 B ), (2) a black dorsum with yellow submarginal spots ( Fig. 22 C ), (3) a reddish mantle and foot ( Fig. 22 D ). All specimens exhibited white-tipped rhinophores.
