Family Turbinidae
updated Oct 2016

Where seen? Among the most commonly encountered of our turban snails on our shores, this chubby snail is often seen on rocky shores and on coral rubble near living reefs. There are suggestions that Turbo intercostalis=Turbo ticaonicus=Turbo bruneus.

3-5cm, up to 6cm. Shell thick with many smooth spiral cords. Chalky operculum is hemi-spherical and smooth, dark green centre with yellowish and white margins. There is a fine ridge on the outside of the operculum and perforation in the centre. Sometimes, the operculum of a dead snail is washed ashore. It is sometimes called a 'cat's-eye'. Body greenish with brown mottles, a pair of slender tentacles.

Sometimes confused with the Top shell snail (Family Trochidae) has a more pyramidal shell and a thin operculum made of a horn-like material. While the turban shell snail has a shell with more distinct whorls and a thick, chalky operculum. Here's more on how to tell apart turban and top shell snails.

Human uses: It is collected for food by coastal dwellers.
