Marble taro shell

The outline of the marble taro snail shell is generally straight, with a slight protrusion near the upper part. The shoulders are angular in shape, with strong nodules to almost smooth. The spiral tower is low to quite high, with contours ranging from slightly concave to slightly concave. The secondary snail layer has nodules ranging from strong to weak. The slope under the last layer of suture line of the adult shell is concave, with 2-4 weak spiral grooves and lines, and the spiral carving is often worn out. The snail layer near the bottom quarter to half usually has weak equidistant spiral ribs. The toxicity of the marble cone snail belongs to protein toxicity, similar to that of venomous snakes, but significantly stronger than that of venomous snakes by several times.
