Rare in the Solitary Islands Marine Park. Found throughout the Indo-Pacific but considered uncommon. In Australia recorded from the Kimberley region of Western Australia and from central Queensland south to northern New South Wales.
Frequents rocky and coral reef, depth to at least 10 m.
Often difficult to recognise due to relatively small size, growth shape and the fact the dorsal surface will be covered in algal and other growth. Underside white with reddish-brown operculum. Feeds on tube worms and boring bi-valves. Grows to 55 mm.
