Marble taro snail shell

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