Description
The size of the shell varies between 30 mm and 70 mm. The shells are oblong, barely arched, and slightly convex. They sport many colours in irregular bands or splotches along the outside of the shell, colours include: lime-green, bright white, and purple-maroon brown. The left side of the shell has many elevated holes set equally distant from each other, and are formed due to the breathing process. These sea snails breath through tubular filaments protruding from each hole, as such, the number of holes in an individual's shell does not change much though its several stages of growth.
Distribution
This species occurs in the Western Indian Ocean from the Red Sea south through most of the eastern coast of Africa, and east to Réunion and Mauritius.
