The color is pale (from white to dirty beige), but the dorsum seems transparent, often greenish grey with yellowish margins, with sometimes darker transverse stripes and a delicate yellow ring. The opening is wide and white, with pronounced denticules. The mantle of the live animal is mottled with black and off-white.
