We saw several of these at night at Red Palm, Heidi's, and other sandy areas. Some consider this a young specimen of Atys naucum. While we did occasionally see both species (or forms) on the same night dives, we prefer to keep them separate for now, not only due to the difference in shell color but also because of the color of the animal.
In Atys naucum, the black and white pattern on the posterior animal seems very different.
