About Thorunna daniellae (Kay & D.K.Young, 1969)
Adults of this species reach a body length between 13 mm and 20 mm. The body is opaque white, with a magenta line that circles the notum just inside the mantle margin. The stalks of the rhinophores are translucent; the rhinophore clubs are orange-red on their anterior side and opaque white on their posterior side. The gills are opaque white with orange-red tips. In very young individuals, the notum is translucent, and has a herringbone pattern of embedded white spicules that starts between the rhinophores and ends at the gills. This species is distributed across the Hawaiian Islands, Midway, and Kure, and is widely distributed throughout the Indo-Pacific.
