 Where 
            seen? This large turban snail is sometimes seen on our 
            rocky shores. It is also sometimes called the Brown turban snail and 
            the scientific name is sometimes spelt as Turbo brunneus.
 
 Features: 3-5cm. Shell thick with 
            spiral cords made up of tiny scales which feel rough. Chalky operculum 
            is hemi-spherical with many tiny bumps, dark green with greyish and 
            white margins. Body 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.
