Where
seen? This narrow conch with black lips is sometimes seen
in seagrass areas on our shores. Elsewhere, they are found on sand
or sandy mud bottoms, sometimes associated with sparse algae. Often
occurring in colonies. Intertidal and sublittoral zones to a depth
of about 40 m. It was previously known as Strombus urceus.
Features: 3-5cm long. Shell heavy thick,
long and narrow, lip slightly flared quite wavy. The flared
shell protects the long proboscis as the animal sweeps the bottom
for titbits. Upperside smooth often covered in silt and sometimes with encrusting plants and animals. Shell opening
is shiny black, although in some, this may appear as just a black border
around the edges of the shell's underside. Body greenish
sometimes with white or with beige spots. Large eyes on
eyestalks, each eyestalk has a tentacle, the purpose of which is not known. Like other conch snails, it hops using the knife-like operculum at the tip of a long muscular foot. |

collected in the Philippines and often sold in the markets of northern
Luzon. Shell frequently used to make decorative items.
Status and threats: The Black-lipped
conch is listed as 'Vulnerable' on the Red List of threatened animals
of Singapore. It used to be abundant in the 1970s. |
