Animals range in colour from orange to red with mottled patches of ornage or yellow. Some specimens can have varying amounts of white dusting, especially on the mantle skirt. The rhinophore clubs can be entirely red or translucent yellow with a red tip. The gills are usually red, tipped with white, but can in smaller specimens be translucent yellow with red tips. In general shape it is very similar to H. sanguineus from the Indo-West Pacific.
