Atys naucum is the common large inflated white bubble shell found in tropical waters.
The brown colour of the shell of living animals is a thin periostracum covering the shell.
It soons dries and flakes off when the animal dies. In juveniles there are often sinuous thin brown lines across the shell.
All species of the genus Atys are herbivorous, related to Haminoea and Phanerophthalmus.
At present most species are tropical and have heavy well-calcified shells. In most cases the true foot is short and
the shell extends a considerable distance beyond its posterior end.
It is possible when more of the many tropical species are studied that they will be placed in other genera.
