Red chut-chut snail
Cerithidea obtusa
Family Potamididae
updated Oct 2016
Where seen? This snail with a distinctive shape is often seen in our mangroves, on tree trunks and on the mud near trees.

Features: 3-5cm long. Shell squat (not so elongated) with ribs of fine beads. Tip usually broken. Shell opening wide usually with a thick flaring lip. Operculum round 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 (Cerithidea quadrata) and Belitong (Terebralia sulcata). 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.
