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.

and top shell snails. |
