A pair of Masked Threefins at a depth of 11 m, Split Solitary Island, New South Wales, 29 January 2010.
Males can be recognised by the dark-coloured posterior half of the body and densely dotted head and 'chest'. Females are greyish green with pinkish scale margins and a dark bar crossing the interorbital (faint in image). They have white bars dorsally on the body that often end in a spot on the lateral line.
The species name 'similis' refers to the similarity in colour and habitat of this species to Enneapterygius hemimelas.
