This species is characterised by the gold mantle border and the red outer edge to the gills and to the tip of the rhinophore clubs. It is similar to Thorunna furtiva but the border in that species is a brownish yellow, and the gills and rhinophores are coloured with brownish yellow. Like most species of Thorunna the gills wiggle rhythmically as the animal is crawling along.
