Where
seen? This snail with a distinctive squat shape is often seen
in our mangroves, on tree trunks, leaves and on the mud near trees.
Features: 3-5cm long. Shell thick squat
(not so elongated) with ribs of fine beads. Tip usually broken. Shell
opening wide usually with a thick flaring lip. Operculum circular and
dark. In addition to a pair of eyes on tentacles, the snail has a
third eye: called the pallial eye on its mantle margin. Other
Malay names include 'Mata merah' which means 'red eyes'. The
living snail does indeed have red eyes! As well as a reddish margin around the foot.
Sometimes confused with the Black
chut-chut and Belitong. More on how
to tell these snails apart. |

Human uses: Chut-chut are eaten in Singapore. They are
boiled and eaten by biting off the tip of the shell and sucking out
the animal. They are also collected for food in other parts of Southeast
Asia. |
