Black-lipped conch
Canarium urceus

Family Strombidae
updated Sep 2020

if you learn only 3 things about them ...
A lively snail that hops instead of creeping along the surface.
Many of its features are adaptations to this hopping lifestyle: flared shell, large eyes.
It is listed among the threatened animals of Singapore.

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.
