Habitat: Can be found in high densities in Characteristics: The shell reaches 28 mm and is white or cream colored with spiral rows of orange-brown to black-brown spots. The operculum is orange-brown at the center and fades to translucent yellow towards the margin. The soft parts of the animal are mostly white with mottled brown on the upper surface. The apex of the adult shell is usually eroded. Juveniles have a 2.5-whorled protoconch. The whorls are very small, white and convex. Flat-topped spiral ridges separate evenly spaced spiral grooves on the early straight-sided teleoconch whorls. The row of most prominent nodules is located just below the suture. Rows of nodules of varying size are separated by very fine spiral threads.
