See text Turbinidae, the turban snails, are a family of small to large marine gastropod molluscs in the superfamily Trochoidea.

This strong operculum serves as a passive defensive structure against predators that try to enter by way of the aperture or that would break the shell at the outer lip.

However, the scientific name Turbinidae is based on the genus name Turbo, which is Latin for spinning top, a child's toy.

However, this is a quite ancient group of gastropods, probably originating in the Permian period 298 to 250 million years ago.

Turbinidae belongs to superfamily Turbinoidea according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
