Description
A globose, smooth-shelled marine snail, commonly known as a moon snail, found on sandy substrates. The shell in the image displays a low spire and a large body whorl, with a coloration ranging from pale brownish-pink to purplish-brown, accented by subtle axial growth lines and a darker apex. Its surface is smooth, typical of the Naticidae family, and it is partially covered with sand grains.
