Scorpion snails are 95-220 millimeters long and are dioecious. The shell is spindle shaped. The height of the spiral tower is moderate, and its layers are weakly keel shaped. The sliding layer of the shell axis is well-developed, and there are usually finger like protrusions on the outer lip. The most distinctive feature is the well-developed eyes, with long and pointed tentacles on the eye stalks that can be freely extended and retracted. The surface of the shell is decorated with rich and colorful carvings. The shell mouth is often narrow and long, with front and rear water pipe grooves, wide and thick outer lips, and a siphon channel at the front end. The serrated edge near the front end of the shell is called the "Phoenix Snail Scar", which is a channel through which the right eye of this snail extends to observe changes in the external environment. Small keratinous pores with serrated edges.
